WARNING: The RJ-45 ports are shielded RJ-45 data sockets. You cannot
use them as standard traditional telephone sockets, or to connect the
unit to a traditional PBX or public telephone network. Only connect RJ-45
data connectors, network telephony systems, or network telephones to
these sockets. You can connect either shielded or unshielded data cables
with shielded or unshielded jacks to these data sockets.
10BASE-T/ The 10BASE-T/100BASE-TX/1000BASE-T ports have RJ-45 connectors and
100BASE-TX/ are configured as Auto MDIX (cross-over).
1000BASE-T Ports
The default state for these ports is auto-negotiation enabled, where the
link’s speed, duplex, and flow control modes are automatically detected
to provide the highest available bandwidth with the link partner.
Download from Www.Somanuals.com. All Manuals Search And Download.
Switch 5500 Family — Front View
17
You can disable auto-negotiation. You can manually configure these
ports to 10 Mbps half duplex, 100 Mbps half duplex,
10 Mbps full duplex, or 100 Mbps full duplex. It is not possible to
manually configure a 1000 Mbps link because auto-negotiation is
mandatory in the 1000 Mbps standard. If you disable auto-negotiation,
Auto MDIX cannot function and the ports become fixed in MDIX
(cross-over) mode.
If you disable auto-negotiation on a 1000 Mbps port, the speed drops to
the highest available speed, which is 100 Mbps by default.
1000BASE-X SFP Ports The 1000BASE-X SFP (Small Form Factor Pluggable) ports support fiber
Gigabit Ethernet short-wave (SX), long-wave (LX), long-haul (LH70), and
copper (T) SFP Transceivers in any combination. This offers you the
flexibility of using SFP transceivers to provide connectivity between the
Switch and remote 1000 Mbps workgroups, or to create a high capacity
aggregated link backbone connection.
The default state for these ports is auto-negotiation enabled, where the
speed, duplex and flow control modes are negotiated. As the speed and
duplex modes are fixed by the media type, only the flow control is
disabled (except 1000BASE-T where auto-negotiation is mandatory) and
the flow control setting can be manually configured.
You can also use these ports for stacking the 5500 SI and EI. For
information about stacking these switches, see the section entitled
“Guidelines For Interconnecting Units” on page 78.
100BASE-X SFP Ports The Switch 5500-EI FX has 24 100BASE-X SFP ports. These are 100Mbps
(Switch 5500-EI FX ports that can use multi-mode fiber optic cables of up to 2km and
only) single-mode fiber optic cables of up to 10km.
You must manually configure duplex and flow control.
The Switch 5500-EI FX supports copper transceivers on the Gigabit SFP
ports only.
Console Port The console port allows you to connect a terminal and perform remote or
local out-of-band management. As the console port on the Switch is an
RJ-45 port, you must connect an RJ-450 to DB9 converter cable to a
standard null modem cable in order to connect a terminal.

information on using the Unit LED for problem solving, see “Solving
LEDs Table 5 lists the LEDs visible on the front of the Switch, and how to read
their status according to color. For information on using the LEDs for
problem solving, see “Checking for Correct Operation of LEDs” on

The Switch 5500 Family has a -48V DC Redundant Power Supply socket.
WARNING: Only properly trained and qualified personnel should install
the Redundant Power Supply (RPS).
WARNING: Make sure to read these instructions in conjunction with the
RPS flyer and the safety and installation instructions supplied with your
RPS.

CHAPTER 2: INSTALLING THE SWITCH
WARNING: When powering any Switch 5500 from an RPS, make sure
that the unit is earthed (grounded) by either connecting the power cord
to the unit or by connecting the earth terminal on the rear of the unit to
a reliable electrical earth (or by connecting both). Ensure that the earth
connection is made before connecting the DC supply from the RPS.
3Com switches that support -48V DC RPS inputs, and are PoE enabled,
can only be powered by an RPS that complies with the isolation
requirements of IEEE-Std 802.3af. Non PoE enabled switches do not have
this restriction.
WARNING: Do not use a standard 'positive-earthed' -48V redundant
power system suitable for use with telecommunications equipment with
the 3Com Power-over-Ethernet (PoE) network switches. In order to meet
the IEEE 802.3af (PoE) specification, the -48V output must be isolated
from earth (ground) and meet the isolation requirements in that
specification.
WARNING: Any RPS must be approved as a SELV output in accordance
with IEC 60950-1/UL 60950-1/EN 60950-1.
WARNING: The characteristics of the Switch 5500 DC supply input are
provided in Appendix C on page 127.
You can power the Switch 5500 using three methods:
■
■
■
AC Mains only — this does not offer any power redundancy. If the
AC mains supply or the AC power supply fails, the switch powers off.
AC Mains and -48V DC (primary supply) — the internal AC supply
acts as the backup in the event of a DC power failure.
DC only — the switch does not need an AC supply and the resiliency
is provided by the DC supply. This is useful in environments where only
DC power is available.
The RPS provides three main benefits:
■
Power Redundancy — if a switch is powered from the mains supply
unit, a failure of the internal power supply causes the switch to fail.
You can avoid this by connecting both the AC and DC RPS supplies to
the switch. You can also add redundancy to the DC power by using
(N+1) DC power supplies to further increase the availability of the
system.

Connecting a Redundant Power Supply
37
■
■
Uninterruptable Power — the system allows easy connection and
maintenance of batteries to the RPS shelf to further increase the
availability of the system.
Additional Power to PoE Ports — the PoE switch’s internal AC
Power Supply provides enough power for most network applications.
You can use the RPS to supplement power (up to a maximum of
15.4W), including full backups of all PoE devices on the network.
Table 13 outlines the behavior of the switch when changes occur to the
power system, such as removing the AC mains cable when the RPS is
attached. The responses to the different power inputs are controlled by
the switch’s internal power supply and not by the RPS.

CHAPTER 2: INSTALLING THE SWITCH
Specifying the 3Com’s redundant power solution allows you to use any off-the-shelf
Redundant Power -48V DC RPS that meets the requirements defined in Appendix C on
System page 127.
For an approved vendor list, more details about purchasing the 3Com
recommended RPS, and a full set of requirements go to:
http://www.3Com.com/RPS
The 3Com recommended RPS generates -48V DC power using power
together so that you can increase the total -48V power available by
adding rectifiers. For example, three 1500W rectifiers can provide up to
4500W. Hot removal or insertion of a rectifier does not affect the -48V
DC output voltage.
Table 14 shows an example of the total power available from several
1500W rectifiers.
A minimum of two rectifiers are required for each shelf to provide N+1
rectifier redundancy.

The unearthed -48V DC power distribution provides the mechanism to
connect to the Switch 5500. The distribution consists of several circuit
breakers and connection terminals for the positive (common) and
negative -48V outputs. Individually connect each Switch 5500 to a circuit
breaker terminal.
You can also connect a battery to battery terminals prior to the DC power
distribution to provide uninterrupted power and to be protected against
the loss of AC mains power.

3Com’s RPS solution uses -48V DC power distribution. The RPS system
provides bulk -48V DC power that is separately distributed to a number
of network switches.
Each RPS consists of a shelf that can house from one to six rectifiers, a
Distribution Module, and a Management Module.
Connecting the When connecting the RPS to the switch, the circuit breaker and 2-core
Switch to the cables need to be matched to the switch’s power rating. Table 15 shows

Using Power over The Switch 5500G-EI Power over Ethernet (PoE) units can supply power
Ethernet to any IEEE 802.3af compliant device through any of its front panel ports
over a Category 5 or Category 5e Ethernet cable. The same cable
connects the device to the network.
The Switch 5500 units can supply power through the 10/100 ports only.
Power over Ethernet is a self-configuring protocol. When you plug a PoE
compliant device into one of the ports on the switch, the switch supplies
the power required to the device, providing that the total power budget
for the switch is not exceeded.
A PoE switch combines the functionality of a standard Ethernet switch
with a single power supply that can power multiple devices. Using a PoE
switch has the following advantages over an non-powered network.
■
Reduced Cabling — a PoE (802.3af) compliant device that has its
power supplied over its Ethernet cable does not require a separate
power supply. If, for example, you use the switch to connect a 3Com
11 Mbps Wireless LAN Access Point 8500 to the network, then only a
network cable is required to provide both power and network
connectivity.
■
Increased Reliability — a device powered by a PoE switch can take
advantage of the facilities available to the switch. You can fit the
switch with a redundant power supply or uninterruptible power
supply to increase its uptime.
The switch supports resistor detection according to IEEE 802.3af and
pre-standard detection methods.

disconnecting the power cord.
Choosing the Correct All of the ports on the switch are Auto-MDIX, that is, they have a
Cables cross-over capability. These ports can automatically detect whether to
operate in MDI or MDIX mode. Therefore, you can make a connection to
one of the ports with a straight-through (MDI) or a cross-over (MDIX)
cable.
The Auto-MDIX feature only operates with auto-negotiation enabled.
If auto-negotiation is disabled, all the switch ports are configured as
MDIX (cross-over). If you want to make a connection to another MDIX
port, you need a cross-over cable. Many ports on workstations and
servers are configured as MDI (straight-through). If you want to make a
connection to an MDI port, you need to use a standard straight-through
cable. See Table 18.
3Com recommends that you use at least Category 5 twisted pair cable.
The maximum segment length for this type of cable is 100 m (328 ft.).

You can create a grounded port by connecting all wires at one end of a
UTP cable to an earth ground point, and the other end to a female RJ-45
connector located, for example, on a switch rack or patch panel. The
RJ-45 connector is now a grounded port.

Inserting an SFP To activate the SFP ports:
Transceiver
SFP transceivers are hot-insertable and hot-swappable. You can remove
them from and insert them into an appropriate SFP port without having
to power down the switch.
1 The SFP transceiver (shown in Figure 18) is keyed so that there is only one
way that you can install it correctly. Hold the transceiver so that the
connector is toward you and the product label is visible. Ensure that the
wire release lever is closed (in the upright position).
2 Gently slide the transceiver into the SFP port until it clicks. If the
transceiver does not click into place, remove it, turn it over and re-insert
it.
3 Remove the plastic protective cover, if fitted.
CAUTION: The dual personality ports on the Switch 5500G-EI enable you
to activate an RJ-45 port, an SFP port, or a mixture of both (for example,
on the 24 Port switch, you can activate the RJ-45 ports 23 and 24 and the
SFP ports 21 and 22 at the same time). If you try to activate the same dual
personality RJ-45 port and SFP port (for example, RJ-45 port 23 and SFP
port 23 at the same time), the SFP port takes priority.

CAUTION: To protect your switch from unauthorized access, you must
change all three default passwords as soon as possible, even if you do not
intend to actively manage your switch. For more information on the
default user names and changing the default passwords, see “Changing
the Default Passwords” on page 73.
IP Configuration You can use one of the following methods to provide IP information to
your switch. This step is essential if you wish to manage your switch over
the network.
Manual IP Configuration
When you configure the IP information, the switch retains that
information that you enter until you change it again.
You should use the Manual IP configuration method if:
■
■
■
you do not have a DHCP or BootP server on your network
you want to remove the risk of the IP address ever changing
your DHCP or BootP server does not allow you to allocate static IP
addresses. Static IP addresses are necessary to ensure that the switch is
always allocated the same IP information.
the switch’s IP information. This makes management simpler and more
reliable since it does not depend on a DHCP or BootP server. It also
eliminates the risk of the IP address changing.
To manually enter the switch’s IP information, refer to the section entitled
“Manually Configuring the IP Information” section on page 61.
Automatic IP Configuration using DHCP
By default, the switch automatically attempts to acquire its IP address
from a DHCP server on the network. If you are using this method, make
sure your DHCP server assigns the switch a static IP address so that you
know what that IP address will be at all times.
If you do not know what the IP address is and it will be difficult to
manage your switch. Most DHCP servers allow static IP address
configurations. Refer to your DHCP server documentation for
instructions.

CHAPTER 3: SETTING UP FOR MANAGEMENT
For a detailed description of how automatic IP configuration operates,
refer to the “Switch 5500 Family Configuration Guide” available on
3Com’s Web Site at www.3com.com.
You should use the automatic IP configuration method if:

Viewing Automatically Configured IP Information
67
You can now set up your switch management method. See “Methods of
Managing a Switch” on page 56 to determine which method is best for
you.
Viewing
If you allow the switch to automatically configure its own IP information,
you need to discover and view the IP information before you can begin to
manage the switch. You can discover the IP information in two ways:
Automatically
Configured IP
Information
■
Using 3Com Network Director to auto-discover the switch and display
the automatically allocated IP information assigned to the switch.
■
Connect a workstation using a console cable to the switch’s console
port. You can then view the IP information automatically assigned to
the switch using the command line interface (CLI).
Using 3Com Network To use the 3Com Network Director application (available from the 3Com
Director Web site) to discover the automatically allocated IP information:
1 Connect your switch to the network.
2 Power-up the switch and wait for two minutes.
3 Launch 3Com Network Director and run the Auto-discovery wizard.
3Com Network Director automatically discovers the new switch and
displays the IP information allocated to the switch.
Most DHCP and BootP servers allow you to configure static IP addresses
so that you know what IP address is given to the switch. Refer to the
documentation that accompanies your DHCP or BootP server for
instructions.
If your network does not have a DHCP or BootP server, the workstation

Viewing IP Information via the Console Port
To view the automatically-allocated IP information using the command
line interface:
1 Connect your switch to the network using the Ethernet cable. As soon as
a network connection is made the switch begins the automatic IP
configuration process.
The automatic IP configuration process usually completes within one
minute.
2 The command line interface login sequence begins as soon as the switch
detects a connection to its console port.

Setting Up SNMP
Management
Any network management application running the Simple Network
Management Protocol (SNMP) can manage a switch if the management
workstation is connected to the switch using a port on the management
VLAN. By default, the management VLAN is 1, and all ports on the
switch are in VLAN 1
You can use the 3Com Network Director, Device manager, EMC and the
OV integration kit (available from 3Com’s Web site) to provide SNMP
management for your switch. 3Com Network Director, Device manager,
EMS, and OV integration kit automatically loads the correct MIBs and
necessary files onto your workstation.
Prerequisites The default read community string is public. To change this setting, in
System View, enter display snmp community.

Changing the Default Passwords
73
The default write community string is private. To change this setting,
in System View, enter display snmp community.
To manage your switch using an SNMP network management
application, you need to specify the same SNMP community strings for
the users defined on the switch and the management application.
You can do this using the command line interface system
management snmp communitycommand. Refer to the command
line interface section of the “Switch 5500 Family Command Reference
Guide” for more information.
SNMP V3 is on as default. All commands are in the SNMP menu in System
View.
Changing the
Default Passwords
If you intend to manage the switch using the Web interface or the
command line interface, or to change the default passwords, you need to
log in with a valid user name and password. The switch has three default
user names, and each user name has a different password and access
level. These default users are listed in Table 22.
CAUTION: To protect your switch from unauthorized access, you should
change all three default passwords as soon as possible, even if you do not
intend to actively manage your switch.

Unit Numbering within the Fabric
How To
Interconnect Units
Up to eight 3Com Switch 5500 units can be interconnected to create an
XRN Stacking Fabric and then treated as a single manageable unit with
one IP address.
You can interconnect your switches to create an XRN Fabric using a
standard 1000 Mbps Ethernet connection. Table 23 lists the different
variants of the Switch 5500 family, how they physically interconnect and
the level of XRN support offered by the Fabric.
It is not possible to create a Fabric by interconnecting a 3Com Switch
5500 with any other 3Com device (such as a 5500G-EI) or mix Enhanced
Image (EI) Switch 5500 units with Standard Image (SI) units.
This section assumes you have either set up your units for management
as detailed in Chapter 3 “Setting Up SNMP Management”or that you are
using a console cable connected to the console port to set up and
allocate IP addresses and so on.
For more information on creating an XRN Fabric, refer to the Installation
Guides that accompany the stacking cable (3C17262) and the resilient
stacking cable (3C17263).

How To Interconnect Units
77
As with all Switch 5500 CLI commands, the format for entering a
number (in the case of the Switch 5500 this will always be 0), z = port
number.
3 Connect the Fabric-enabled ‘up’ port on one Switch 5500 unit to the
Fabric-enabled ‘down’ port on another Switch 5500 unit using the
4 To create a fully resilient Fabric: enable the spare Fabric ports on the
top-most and bottom-most units in the Fabric as described in the
previous steps. Then insert a cable into these two Fabric ports to create a
link between the top-most and bottom-most units in the Fabric, as shown
in Figure 31 on page 79.
This ensures that in the event of a unit failure within the Fabric, the Fabric
will continue working and no “Fabric split” will occur.
Save all configuration settings. From the User View, enter the save
command to save the configuration to your switch.
Stacking Switch 5500G-EI Units
1 Ensure that the switch units that you wish to interconnect have the latest
software agent installed. You can use the display version
command to check this.
2 Connect the stacking cable ‘up’ port on one Switch 5500G-EI unit to the
stacking cable ‘down’ port on another Switch 5500G-EI unit using a
stacking cable (3C17262) or a resilient stacking cable (3C17263).
Note the color code on the stacking cable connectors should match the
color code on the stacking ports, that is, blue for the ‘up’ port that is
that is connecting to the physically lower unit.
3 To create a fully resilient Fabric: using the ‘up’ stacking cable port on the
top-most and the ‘down’ stacking cable port on the bottom-most units
insert a stacking cable to create a link between the top-most and
bottom-most units in the Fabric, as shown in Figure 31 on page 79.
This ensures that in the event of a unit failure within the Fabric, the Fabric
will continue working and no “Fabric split” will occur.

CHAPTER 4: CREATING AN XRN STACKING FABRIC
Guidelines For
Interconnecting
Units
This section offers some guidelines for creating a Fabric. Using these
guidelines will help prevent problems arising when setting up your Fabric.
■
The maximum number of switch units that can be interconnected is
eight.
■
It is not possible to create a Fabric by interconnecting a 3Com Switch
5500 with any other 3Com device (such as a 5500G-EI) or mix
Enhanced Image (EI) Switch 5500 units with Standard Image (SI) units.
■
■
3Com strongly recommends that you upgrade all switches to be
interconnected to the latest software agent.
3Com recommends that you remove the configuration file from a
switch unit that has previously been used elsewhere in your network
before you interconnect to an existing unit. If you do not do this,
problems may be caused by conflicting switch configurations. Use the
dircommand from the User View to display the configuration files
stored on the switch and locate the [filename].cfgfile. Do NOT
under any circumstances remove the 3comoscfg.deffile (this is the
default configuration file).
For a detailed description of how XRN Technology operates and
implementation guidelines, refer to the “Switch 5500 Family
Configuration Guide” available on the 3Com Web Site at
www.3com.com.
Unit Numbering
within the Fabric
When a Fabric is created using the Switch 5500 the unit numbering can
be determined in two ways.
■
You can manually assign unit IDs 1 to 8 to specific units using the
change[self-unit, unit-id] to [1-8,
auto-numbering]command from the System View. If you
manually assign unit IDs to a switch via the changecommand the IDs
will be retained after a power cycle.
If you add a unit to a Fabric that has previously been manually
configured with a unit ID and this conflicts with an ID already within
the Fabric, then the switch with the lowest MAC address assumes the
ID in question and the other unit will automatically renumber.
3Com recommends that you manually assign the unit IDs within the
Fabric if you wish to have predictability of knowing which units have
which IDs at all times.
■
Fabric topology is ‘discovered’ and the units auto-number their IDs.
Download from Www.Somanuals.com. All Manuals Search And Download.
Unit Numbering within the Fabric
79
Adding and removing units from the Fabric does not cause any
renumbering to occur and the Fabric will continue to work normally.
Renumbering only occurs when the Fabric is next power cycled if the
units are configured to auto-number.
The unit LEDs will display the unit number in the Fabric, from 1 to 8.

CHAPTER 5: PROBLEM SOLVING
Solving Problems
Indicated by LEDs
If the LEDs on the switch indicate a problem, refer to the list of suggested
solutions below.
The PWR LED does not light
Check that the power cable is firmly connected to the switch and to the
supply outlet. If the connection is secure and there is still no power, you
may have a faulty power cord or an internal fault. Firstly, check the power
cord by:
■
testing it in another device.
■
connecting a working power cord to the ‘problem’ device then
contact your supplier for advice.
On powering-up, the PWR LED lights Red
The switch unit has failed its Power On Self Test (POST) because of an
internal problem. The fault type will be indicated on the unit LEDs.
Contact your supplier for advice.
On powering-up, the PWR LED is flashing yellow
A port has failed and has been automatically disabled. You can verify this
by checking that the Port LED is quickly flashing Yellow. If a port fails, the
switch passes its Power On Self Test and continues to operate normally.
A Port LED is flashing yellow
The port has failed and has been automatically disabled. The switch
passes its Power On Self Test and continues to operate normally, even if
one or more ports are disabled.
A link is connected and yet the Port LED does not light
Check that:
■
The switch and the device at the other end of the link (or cable) are
connected securely.
■
■
■
The devices at both ends of the link are powered-up
The quality of cable is satisfactory
Auto-negotiation settings are the same at both ends.
Download from Www.Somanuals.com. All Manuals Search And Download.
Solving Hardware Problems
83
Auto-negotiation problems will occur with 10BASE-T or 100BASE-T
where auto-negotiation is disabled and incorrect cables are being used
(cross-over or straight)
Auto-negotiation problems will occur with fiber if:
■
The Receiver (RX) and Transceiver (TX) cable connectors are
swapped
■
■
Fibers are broken
Auto-negotiation differs at either end (a link appears at the ‘fixed’
end and not at the auto-negotiation end)
Solving Hardware
Problems
In the rare event of your switch unit experiencing a hardware failure, refer
to the list of suggested solutions below.
A fan failure warning message is received
Your switch has a fan monitoring system that will generate fan failure
warning messages. Fan failure could potentially reduce the lifetime of the
switch. The monitoring system polls the fan status at periodic intervals
while the unit is powered up.
If one fan has failed in the switch, a warning message will be generated
in the following ways:
■
Unit LED — the seven segment display will show a green flashing ‘f’.
■
RMON Trap — if configured, an RMON trap is generated and sent to
the management workstation.
■
Command Line Interface — an indication of a general hardware
failure is provided through the Top level menu displayed when logging
on to the CLI. For more detailed information about the failure select
the display logbuffer command.
■
Web interface — an indication of fan failure is provided through the
Device Summary table for the specific unit. In addition all Summary
tables turn red to indicate the fan failure.
If a fan failure warning message is generated:
1 Power off the unit.
2 Check that the air vents are not obstructed.
Download from Www.Somanuals.com. All Manuals Search And Download.
84
CHAPTER 5: PROBLEM SOLVING
3 Power cycle the unit. To do this, remove and reconnect the AC mains
supply. If the unit has no AC main supply, remove and reconnect the DC
RPS supply.
4 If another fan failure warning message is generated via the Command
Line Interface or the Web interface, return the unit to 3Com.
Unit fails, no SNMP fan failure message is received
1 Power cycle the unit. To do this, remove and reconnect the AC mains
supply. If the unit has no AC mains supply, remove and reconnect the DC
RPS supply.
2 Check the command line interface (display logbuffer command)
to determine whether a thermal shutdown has occurred.
3 If no, return the unit:
If yes, check that:
■
The air vents are not obstructed.
■
The ambient temperatures and environmental conditions meet those
specified in Appendix C on page 127.
4 Power cycle the unit. If a further thermal shutdown occurs, and all
environmental conditions are satisfactory, return the unit to 3Com.
The switch has identified that the SFP does not meet the minimum
requirements for the switch and has disabled the port. To correct this
problem, completely remove the SFP and replace it with a 3Com
approved SFP. See “Approved 1000BASE-X SFP Transceivers” on page 47
and “Approved 100BASE-X SFP Transceivers” on page 48.
Error message indicating that the SFP transceiver is faulty
To correct this problem, completely remove the SFP and then reinsert it.
Alternatively, insert another identical SFP. If the problem persists, contact
3Com Technical Support.

■
■
If the switch is separated from your management application by a
router, ensure that the default gateway IP address within the switch is
the same as the IP address of the router.
The switch’s IP address has been entered correctly in your network
management application (such as 3Com Network Director).
The following is a brief overview of IP addressing, and how to obtain a
registered IP address.
IP Addressing
To be managed correctly, each device on your network (for example a
switch or Hub) must have a unique IP address. IP addresses have the
format n.n.n.n where n is a decimal number between 0 and 255. An
example IP address is 192.168.100.8.
The IP address is split into two parts:
■
■
The first part (‘192.168.100’ in the example) identifies the network on
which the device resides
The second part (‘.8’ in the example) identifies the device within the
network
The natural subnet mask for this example is 255.255.255.0.
If your network has a connection to the external IP network, that is, you
access the Internet, you must apply for a registered IP address.
How do you obtain a registered IP Address?
The IP registration system ensures that every IP address used is unique; if
you do not have a registered IP address, you may be using an identical
address to someone else and your network will not operate correctly.
InterNIC Registration Services is the organization responsible for
supplying registered IP addresses. The following contact information is
correct at time of publication:
World Wide Web site: http://www.internic.net
If your IP network is internal to your organization only, that is, you do not
access the Internet, you may use any arbitrary IP address as long as it is
not being used by another device on your network. 3Com suggests you

subnet mask of 255.255.255.0.
These suggested IP addresses are part of a group of IP addresses that
have been set aside specially for use ‘in house’ only.
A device is connected to a Switch 5500-EI PWR or Switch 5500G-EI
but power is not being supplied
If power is not being supplied to a device connected to a Switch 5500
PWR, you should do the following checks:
■
Check that the device is compliant with the 802.3af standard ref. [18].
The 5500-EI PWR will supply power through the front panel ports to
802.3af compliant and many pre-standard devices.
■
Check that power budget for the switch has not been exceeded.
If the power budget has been exceeded, then by default, the powered
device connected to the Power over Ethernet port with the lowest
priority port will lose power. However, if all the devices connected to
the switch have equal priority levels, then the port with the highest
number will lose power.
By default, the switch will allow a device to receive power as long as
Power over Ethernet power supply has 18 watts spare in its power
budget. If this much power is not available, the device will not be
powered (unless it has a higher priority than existing powered ports)
and a PoE fault will be reported for that port. If enough power
subsequently becomes available, the port will be powered.
■
Check that the port has not had a power limit imposed on it.
The Switch 5500 PWR units do not provide PoE on the Gigabit SFP ports.
Solving Fabric
Formation
Problems
If you are having problems with correctly forming a fabric, first ensure
that Spanning Tree is enabled. If it is enabled, do the following:
1 Power off all units in the fabric.
2 Check all the cable connections in the fabric.
3 Check the ports have been enabled as fabric ports.
4 Power on all units in the fabric.

Bundled files with the extension NetMan.zip, can be used to upgrade
your switch using the 3Com Network Director Agent Update. Any
attempt to upgrade individual .web, .btmor .appfiles using 3Com
Network Director will fail. These files should be used to upgrade your
switch as described below.
Any attempt to upgrade the switch directly with xxxxxxxx.exeand
xxxxxxxxNetMan.zipwill fail. The individual .web, .btmor .app
files should be used to upgrade your switch as described below.
Upgrading from the
Command Line
Interface
This section describes how to upgrade files to your switch from the
Command Line Interface (CLI).
Introduction Before upgrading the software to your switch from the CLI, it is important
to check the contents of the flash to ensure that there is enough space to
download the new files.
The flash space needed for the new files is approximately 5.5 MB.
1 To check the contents of the flash, logon to your switch either via a telnet
connection or directly via the console to display the User View in the CLI
and enter the following:
dir unit1>flash:
A file list similar to the following is displayed:

2 You can check the contents of the flash for the remaining units in the
fabric by entering:
dir unit2>flash:
dir unit3>flash:
dir unit4>flash:
dir unit5>flash:
dir unit6>flash:
dir unit7>flash:
The file list should contain one of each file type (.web, .def, .cfg
and .app).
3 Any additional files should be considered for deletion to allow maximum
space for downloading the new files. To delete a file from the list enter:
delete/unreserved unit1>flash:/filename
To delete files from the list for the remaining units in a fabric, replace
unit1with unit2(on the next line) and so on for each switch in the
fabric.
4 The /unreservedoption will cause the file to be deleted from both the
flash and the recycle-bin. To check that deleted files have been removed
from the recycle-bin enter the following:
reset recycle-bin unit1>flash:/
If the recycle-bin is empty the following is displayed:
% File can’t be found “unitN>flash:/”
To check that deleted files have been removed from the recycle-bin for
the remaining units in a fabric, replace unit1with unit2and so on for
each switch in the fabric.

CHAPTER 6: UPGRADING SOFTWARE
The following steps enable you to backup each switch in the fabric:
1 The default configuration file must have the name 3ComOScfg.def.
This file is only used if there is no active configuration file (.cfg) in the
flash file system. The default configuration file is the same for every
Switch 5500 of the same type (i.e Switch 5500 28-port) and is different
to the file for a Switch 5500 of a different type (i.e Switch 5500 52-port).
A sample default configuration file is provided by factory default with the
switch and is not supplied in this upgrade.
Enter the following command:
more 3comoscfg.def
The display similar to the following shows on the first line of the file:
#28-port 3com version 3.1.4
This file is infrequently changed, so the version number may not match
the application software version number.
The default configuration file can be created by saving the configuration
and renaming the xxx.cfgfile as 3ComOScfg.def.
To back up the default configuration file on each switch in the fabric,
enter:
copy unit1>flash:/3ComOScfg.def
unit1>flash:/030100cfg.def
Replace unit1with unit2and so on for each switch in the fabric.
2 The active configuration file can been given any name, provided it ends in
the extension .cfg. 3Com recommends that each fabric is given a
unique configuration file name so that when the file is saved to an
external TFTP server, it is clear which fabric the file belongs to.
To back up the active configuration file on each switch in the fabric,
enter:
copy unit1>flash:/3ComOScfg.cfg
unit1>flash:/030100cfg.cfg
Replace unit1with unit2and so on for each switch in the fabric.
3Com recommends that you save the active configuration file for each
switch in the fabric is also saved to an external storage device. To save the
active configuration file to a TFTP server in User View enter:
tftp aaa.aaa.aaa.aaa put unit1>flash:/3ComOScfg.cfg
3ComOScfg_1.cfg

(where aaa.aaa.aaa.aaa is the IP address of the TFTP server)
Replace unit1with unit2and _1.cfgwith _2.cfgand so on for
each switch in the fabric.
3 The Web user interface file and the application file must be the same on
all switches in the fabric. It is not necessary to backup these files because
they will have a new version number.
1 To download the application file, enter:
tftp aaa.aaa.aaa.aaa get s4a03_01_04s56.app
(where aaa.aaa.aaa.aaa is the IP address of the TFTP server)
