Preface  
The 3Com Switch 8800 Family of Routing Switches (referred to as the Switch 8800  
Family) are intelligent, multi-layer modular LAN switches and are ideal for  
enterprise environments where non-stop availability of critical applications and the  
highest performance, security, and granular control are required. The Switch 8800  
Family delivers high density Gigabit and 10 Gigabit switching in an integrated  
chassis platform. Built-in support for IPv6, MPLS, Power over Ethernet (PoE), and  
1.44 Tbps backplane capacity ensures unprecedented investment protection.  
Resilient Layer-3 routing, hot-swap modules, and redundant power, along with  
sub one-second fabric fail over on the Switch 8800, ensure (24 x 7) availability to  
support the most demanding enterprise core and campus environments.  
Advanced Quality of Service features such as bandwidth management and packet  
classification optimize quality for real-time voice and video applications. Intrusion  
prevention security capabilities such as IEEE 802.1X Network Login and Access  
Control Lists ensure that only authorized users can access network resources.  
The Switch 8800 is focused on delivering functionality towards the higher end of  
the large Enterprise, with a 4-port 10 Gigabit Module, high density 48-port  
Gigabit Modules, as well as a group of Advanced Modules with support for larger  
routing tables and/or MPLS. Power over Ethernet (PoE) is built into all Switch  
8800s.  
Application modules for the Switch 8800 provide the flexibility to add a firewall,  
IPsec encryption, network monitoring with NetFlow, and Layer 2 VPN networking  
using Virtual Private LAN Service (VPLS) by simply adding a module to the chassis.

PoE Power Supply The Switch 8800 Family supports Power over Ethernet (PoE). With this feature, a  
Switch 8800 Family switch equipped with an external PoE power supply and  
PoE-capable modules can deliver 48 VDC to its remotely powered devices (PDs,  
such as IP phones, WLAN APs and network cameras) through twisted pairs.  
The Switch 8800 Family can supply power to remote PDs through the Ethernet  
electrical ports on the I/O modules. Each I/O module can simultaneously supply  
power to up to 48 PDs with the maximum distance of 100 m (328.1 feet).  
Each Ethernet port can deliver up to 15.4 W to its PD.  
14  
CHAPTER 1: PRODUCT OVERVIEW  
A Switch 8800 supports up to 4500 W (220 V)/2250 W (110 V) power to its  
PDs. It determines whether to deliver power to a newly detected PD depending  
on the power it currently supplied.  
PoE entry area  
The PoE-supported Switch 8807/Switch 8810/Switch 8814 chassis has a PoE entry  
area between the two power supply units. You can insert a PoE 3C17510 Switch  
8800 PoE Entry Module into this area, and connect this module to a 3C17509  
Switch 8800 External PoE Power Rack so as to import the output power of the  
External Power Rack unit.

monitoring module reports the running information of the PSUs in the system to a  
fabric through RS232 or RS485 interface and indicates alarm status by the alarm  
LED (ALM). You can connect cables to the interfaces from the front as well as the  
rear of the frame.  
The external PoE power system for the Switch 8800 Family only supports the  
RS485 monitoring interface.

MBUS Introduction  
The MBUS is a service-independent maintenance and test bus. No service traffic  
goes through the MBUS. The shutdown and reset of the MBUS does not affect the  
services on the switch, and faults that have occurred on modules do not affect the  
MBUS.  
Through the MBUS, the system instructs the MBUS modules on individual cards to  
power on/off the cards one by one in turn, thus prevent power surging. The MBUS  
module software must support online upgrade.  
 
16  
CHAPTER 1: PRODUCT OVERVIEW  
Role and function  
The MBUS system is powered by 5 V from the MBUS on the fabric. The 5 V power  
on the two fabrics are redundant to each other.  
Each MBUS module is attached to the MBUS, which contains two control lines:  
MBUS0 and MBUS1.  
Each card has an independent MBUS module, those on the fabrics are primary  
MBUS modules, and those on application modules are secondary MBUS modules.  
When the fabrics operate in redundancy mode, the MBUS module on the active  
fabric is the active module, and the one on the standby fabric is the standby  
module.  
The MBUS uses a controller area network (CAN) bus as its control bus, that uses  
the 1:1 hot backup and transfers control information at 1 Mbps.  
Fan Tray  
The Switch 8807 uses one 25 W fan tray, which contains four 120 x 120 x 25.4  
mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two  
modes: fabric-controlled or temperature-controlled. They operate at -48 VDC  
supplied from the backplane.  
The Switch 8810 uses one 35 W fan tray, which contains six 120 x 120 x 25.4  
mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two  
modes: fabric-controlled or temperature-controlled. They operate at -48 VDC  
supplied from the backplane.  
The Switch 8814 uses two 25 W fan trays, each of which contains four 120 x  
120 x 25.4 mm (4.7 x 4.7 x 1.0 in.) axial fan units (and totally eight for the two  
fan trays). The fans can be governed in two modes: fabric-controlled or  
temperature-controlled. They operate at -48 VDC supplied from the backplane.

Safety  
Recommendations  
To avoid possible bodily injury and device impairment, please read the following  
safety recommendations carefully before installing the Switch 8800 Family. The  
recommendations do not cover every possible hazardous condition.  
General Safety  
Recommendations  
The Switch 8800 Family use redundant PSUs. Turn off all PSUs and remove all  
the power cords before opening the chassis.  
Keep the chassis clean and dust-free.  
Keep the chassis and installation tools away from walk areas.  
Safety  
Recommendations  
against Electricity  
Look carefully for possible hazards in your work area, such as ungrounded  
power extension cables, missing safety grounds, and moist floors.  
Locate the emergency power-off switch in the room before installation. Shut  
the power off at once in case accident occurs.  
Unplug all the power cords and external cables before moving the chassis.  
Do not maintain the equipment alone when it has been powered.  
Never assume but check each time that power has been disconnected from a  
circuit.  
Do not place the switch on a moist area and avoid liquid flowing into the  
switch.  
Safety The Switch 8800 Family are rather big and heavy, so follow the recommendations  
Recommendations in below when moving it.  
Moving the Switch 8800  
Family  
Remove all the external cables (including power cords) before moving the  
chassis.  
Do not move the switch alone. Work with another person.  
Move the switch slowly and stably. Never move suddenly or twist your body.  
Move the switch at stable and consistent paces with your peer. Keep balance of  
your body.  
CAUTION: You can only hold the handles at both sides of the chassis when  
moving the switch, but not the plastic panel of the chassis, the handle of the fan  
frame, the handle of the PSUs or the air vents of chassis.  
c
As these parts are not designed for bearing the weight of the entire chassis, any  
attempt trying to carry the switch with these parts may impair the switch and even  
injure yourself.  
     
50  
CHAPTER 3: INSTALLATION PREPARATION  
Wearing an To prevent the electronic components from being damaged by the electrostatic  
ESD-Preventive Wrist discharge (ESD), take ESD measures for the area where the switch is located and  
Strap note the issues below:  
Always wear an ESD-preventive wrist strap when installing the parts, especially  
the electric printed circuit boards.  
Hold the circuit board by the edge. Do not touch the components or the  
electric printed circuit.  
Take the following steps to use the ESD-preventive wrist strap.  
Step 1: Wear the wrist strap on your wrist.  
Step 2: Lock the wrist strap tight around your wrist to keep good contact with the  
skin.  
Step 3: Insert it into the hole peculiar to ESD-preventive wrist strap in the chassis  
or attach it to the grounding screw of the chassis the alligator clips.  
Step 4: Make sure that the ESD-preventive wrist strap is well grounded.  
CAUTION: For the sake of safety, check the resistance of the ESD-preventive wrist  
strap. The resistance reading should be in the range of 1 to 10 Mohm between  
human body and the ground.  
c
Safety Some I/O modules of the Switch 8800 Family have optical interfaces. In operating  
Recommendations status, it is dangerous to stare into the open optical interface because the laser  
against Laser being transmitted through the optical fiber produces a small beam of light which  
has very high power density and is invisible to human eyes; when a beam of light  
enters the eye, retina may be burned.  
CAUTION: The laser inside the optical fiber may hurt your eyes.  
c
Examining Installation  
Site  
The Switch 8800 Family can only be used indoors. To ensure that the switch works  
normally and to prolong its service lifetime, the following requirements should be  
met in terms of installation environment.  
Temperature/Humidity To ensure the normal operation and service lifetime of a switch, proper  
Requirements temperature and humidity should be maintained in the equipment room.  
Long-lasting high humidity in the equipment room is prone to poor insulation or  
even leakage of the insulating material. Sometimes, the mechanical performance  
deterioration, the rustiness and corrosion of some metal parts are also more likely  
to occur. If the relative humidity is too low, the captive screws may become loose  
due to the insulation washer contraction. Meanwhile, the electrostatic is likely to  
be produced in the dry environment, which will jeopardize the CMOS circuit of the  
switch. The higher the temperature, the greater the damage it will do to the  
switch. Long-lasting high temperature will speed up the aging process of the  
insulating materials, greatly lower the reliability of the switch, and therefore affect  
its service life seriously.  
 
Examining Installation Site  
51  
Cleanness Requirements Dust is a hazard to the operating safety of the switch. The indoor dust  
accumulated on the chassis can cause electrostatic absorption, which may result in  
the poor contact of the connector or metal contact point. This happens more  
frequently when indoor relative humidity is low, which will not only shorten the  
service life of the switch, but also cause communication failure.  
The required specifications on dust content and particle diameter in an equipment  
room are shown in the following table.  
Table 68 Limitation on dust content in equipment room  
Mechanical active material Unit  
Content  
Dust particle  
particles/m3  
3 x 104  
(No visible dust on desk in three days)  
Note: Dust particle diameter ‚5µm  
Besides the dust specifications, the equipment room of the switch should also  
meet the rigorous requirements for the content of salt, acid and sulfide in the air.  
These harmful gases could accelerate the metal erosion and the aging process of  
some parts. Incursion of harmful gases, such as SO2, H2S, NO2, NH3, and Cl2,  
should be prevented. The specific limitation values of these harmful gases are  
given in the following table.

Anti-Static Any possible interference sources, no matter outside or inside the system, affect  
Requirements the switch in use in a way of capacitive coupling, inductive coupling,  
electromagnetic radiation, common impedance (including the grounding system)  
coupling or conducting line (power line, signaling line and transmission line etc.).  
To prevent the interference, you should:  
Take effective measures against electrical net interference for power supply  
system.  
Separate the working ground of the switch from the grounding device of the  
power supply equipment or lightning-protection grounding device as far as  
possible.  
Keep the switch far away from the radio launcher, radar launcher, and  
high-frequency devices working in the high current.  
Adopt electromagnetic shielding if necessary.  
Grounding A good grounding system is not only the basis essential to the stable and reliable  
Requirements switch operation, but also an important guarantee of lightning protection,  
anti-interference and ESD-prevention. The user must provide good grounding  
system for the switch.  
52  
CHAPTER 3: INSTALLATION PREPARATION  
Power Supply The Switch 8800 Family adopts redundant PSUs for AC PSU:  
Requirements  
Rated voltage: 100 VAC to 240 VAC, 50 Hz or 60 Hz  
Maximum tolerance: 90 VAC to 264 VAC, 50 Hz or 60 Hz  
Maximum power output: 1200 W (Switch 8807)/2000 W (Switch 8810/Switch  
8814)  
Space Requirements For the sake of adequate ventilation and easy equipment maintenance, you are  
recommended to keep one meter of clearance between the rear/front of the  
switch cabinet and the wall surface or other devices. If the optional cabinet is  
desired, the clear height of the equipment room must be more than 3 meters  
inclusive.  
Cabinet-Mounting Before cabinet-mounting the switch, make sure that the cabinet meets the  
Requirements following requirements:  
Better mount the switch in an open cabinet. However, if you want to mount it  
in a closed cabinet, make sure of the availability of a good ventilation system.  
Make sure that the cabinet stands steadily enough to support the weight of the  
switch and the accessories.  
Make sure that the switch fits the cabinet size. Leave some clearance beside  
the left and right panels of the switch for chassis ventilation.

Mounting the Switch in Take the following steps to install the Switch 8800 Family in a 19-inch cabinet.  
the Cabinet  
Step 1: Confirm before installation  
Make sure that the cabinet has been well fixed. The layout inside the cabinet  
for switch installation has been well done and there is no obstruction inside or  
around the cabinet.  
Make sure that the switch is ready for installation and has been carried to a  
place convenient for further moving near the cabinet.  
Step 2: Mount a shelf inside the cabinet depending on the position where you  
want to put the switch.  
Step 3: Install the cabling rack and attach the mounting ears shipped with the  
switch onto the switch.  
Step 4: Carry the switch at both sides with another person to the place in front of  
the cabinet slowly.  
Step 5: Lift the switch a little higher than the cabinet shelf, put it on the shelf, and  
push it into the cabinet.

Step 6: Align the mounting ears with the square holes in the posts of the cabinet,  
and fasten the screws in the holes to fix the switch in the cabinet.  
Connecting PGND  
Wire and Power Cord  
Connecting PGND Wire  
CAUTION: For the safety of operators and equipment, the switch must be well  
grounded. The resistance reading between switch chassis and the ground must be  
less than 1 ohm.  
c
Common grounding environment  
Step 1: Remove the screw from the grounding hole in the switch chassis.  
Step 2: Wear the connector of the PGND wire accompanied with the switch on  
the grounding screw.  
Step 3: Insert the grounding screw into the grounding hole and screw it down.  
Step 4: Connect the other end of the ground wire to the ground bar of the switch.  
Generally, the cabinets installed in equipment rooms are equipped with ground  
bar. In this case, you can connect the PGND wire of the switch to the ground bar  
for it.

Other grounding environment  
Following are some methods for grounding the switch in different grounding  
environments that you are likely to encounter when installing the switch at  
different places.  
Rather than specifying the switch model or showing the actual location of the  
switch power input or grounding screw, the following figures are primarily  
intended for illustrating the switch grounding, either via grounding screw or  
power input, in specific grounding environments.  
If a ground bar is available, attach one end of the yellow-green PGND wire of  
the switch to a grounding bolt of the ground bar and fasten the captive nuts.  
Note that the fire main and lightning rod of a building are not suitable for  
grounding the switch. The PGND wire of the switch should be connected to  
the grounding device in the equipment room. (For the Switch 8800 Family, the  
grounding screw is on the rear panel. Connect it as illustrated in Figure 38).

If there is no ground bar but earth nearby and the grounding body is allowed  
to be buried, you can simply hammer an angle iron or steel pipe no shorter  
than 0.5 m into the earth. In this case, the yellow-green PGND wire should be  
welded with the angle iron (steel pipe) and the joint should be processed  
against eroding. (For the Switch 8800 Family, the grounding screw is on the  
rear panel. Connect it as illustrated in Figure 38).

Connecting console cable  
Take the following steps to connect the console cable, when configuring the  
switch on the terminal.  
Step 1: Plug the DB-9 or DB-25 female connector of the console cable into the  
serial port of the PC/terminal where the switch is to be configured.  
Step 2: Connect the RJ-45 connector of the console cable to the console port of  
the switch.  
 
68  
CHAPTER 4: SWITCH INSTALLATION  
The PC serial port is not hot-swappable, so you are not allowed to insert or  
remove the console cable into or from the PC serial port.  
n
When connecting the console cable, first connect the DB9/DB25 end to the PC  
serial port and then the RJ45 end to the console port of the switch. And removing  
the console cable is just in inverse order.  
When removing the console cable, first remove the RJ-45 end and then the  
DB9/DB25 end.  
Connecting AUX Cable You need an AUX cable when configuring the Switch 8800 Family with the remote  
modem dial-up approach.  
Introduction  
AUX cable is an 8-core shielded cable. At one end of the cable is an  
RS-232-compliant RJ-45 connector that can be plugged into the console port of  
the switch. At the other end are DB-9 (male) connector and DB-25 (male)  
connector. You can plug either of them into the DB-9 (female) or DB-25 (female)  
port of the modem as needed. The following figure illustrates the AUX cable.

Connecting category-5 shielded cable  
Step 1: Plug one end of the network cable into the desired Ethernet RJ-45  
connector on the switch.  
Step 2: Plug the other end of the cable into the RJ-45 port of the peer device.  
Connecting Fiber  
All the megabit and gigabit optical modules available for the Switch 8800 Family  
are SFP modules that provide LC user ports.  
n
Introduction to fiber connector  
When selecting a fiber network facility, make sure that the type of the  
connector and the fiber match the adopted optical port.  
n
Before connecting the fiber, make sure that the receive-end optical power does  
not exceed the upper threshold of the receiving optical power. Excessive  
receiving optical power is very likely to burn the optical module.  
Fiber connectors are indispensable passive components in an optical fiber  
communication system. Their application allows the removable connection  
between optical channels, which makes the optical system debugging and  
maintenance more convenient and the transit dispatching of the system more  
flexible. Among various fiber connectors, only LC connector will be introduced  
here.  
LC fiber connector  
70  
CHAPTER 4: SWITCH INSTALLATION  
Figure 51 LC connector  
Connecting fiber  
Step 1: Plug one end of the fiber into the SFP optical module of the Switch 8800  
Family.  
Step 2: Connect the other end of the fiber into the corresponding device.  
CAUTION: When the optical interface has not been connected with a fiber  
connector or its dust-proof mesh is open, there might be some invisible radiation  
emitted from the optical interface. So do not look into the optical interface  
directly.  
c
Cover the optical interface if there is no connector plugged in.  
Cable Routing  
Recommendations  
Freestanding Switch on For only selling an integrated chassis, you do not have to care about the cabling  
Tabletop inside or outside the cabinet. All the I/O module cables are routed from the left  
side of the chassis (along the cabling channel), and the chassis power cords  
(AC/DC power cords) are routed in the front of the chassis.  
Cabinet-Mounting If the switch is mounted in a 19-inch standard cabinet or B68-22 cabinet, the I/O  
Switch module cables are bound on the cabling rack at the left side of the chassis and are  
routed up or down to pass through the chassis top or the raised floor depending  
on the available equipment room condition (that is, the signal cables are routed  
into the chassis either from the cabling rack on the chassis top or from the cabling  
trough under the floor) of the exchange office. The power cords run along the  
left-front of the chassis and out of the chassis either from the top or the raised  
floor depending on the equipment room conditions (DC power distribution  
cabinet, lightning protection box, and terminal block, etc.) of the exchange office.  
Cable Management  
Cable Management  
Requirements  
Bundle and put the cables inside the cabinet in a straight and neat way. No  
intertwinement or bending is allowed.  
   
Cable Management  
71  
Figure 52 Cable bundling example I  
Intertwined  
Bent  
The bending radius of cable body cannot be less than twice of the cable  
diameter. The bending radius of the cable cannot be less than 5 times of its  
diameter at the place where it is led out of the connector;  
Different cables (power cord, signal cable, PGND wire, etc.) should be cabled  
and bundled separately rather than together in the cabinet. If they are close to  
each other, you can cable them in cross-shape. For parallel cabling, the space  
between power cord and signal cable should be no less than 30 mm (1.2 in);  
The cable binding rack and cabling channel inside and outside the cabinet  
should be smooth and without sharp edges or tips;  
The metal cable management hole should have a smooth and fully rounded  
surface or wear a insulating bush;  
Use the right type of ties to bundle the cables. Do not bundle cables with  
joined ties. 3Com Corporation provides the following types of ties: 100 x 2.5  
mm (3.9 in x 0.1 in), 150 x 3.6 mm (5.9 x 0.1 in), 300 x 3.6 mm (11.8 x 0.1 in),  
530 x 9 mm (20.9 x 0.4 in), and 580 x 13 mm (22.8 x 0.5 in);  
Cut the extra parts of the ties neatly after bundling the cables, leaving no sharp  
or angular tips. See the following figure:  
Figure 53 Cable bundling example II  
72  
CHAPTER 4: SWITCH INSTALLATION  
Bundle the cables wherever cable bending cannot be avoided. However, the  
cable ties cannot be placed inside the bending area in case of the likelihood of  
cable core break due to excessive stress. See the following figure.  
Figure 54 Cable bundling example III  
The spare cables or excessive cable parts should be folded and bundled and  
placed at a right place in the cabinet or on the cabling channel. A “right place”  
refers to the place where the cables will not affect the operation of the device  
or impair the device, or be damaged;  
The power cords cannot be tied on the guides of any mobile components;  
Reserve some redundancy for the cables connecting to the mobile parts, the  
PGND wire of the door for example, to free the cables from possible stress.  
Such a mobile part should be installed in such a way that the extra cable  
segments will be kept from contacting the heat source, sharp points or edges.  
Use high temperature cables near the heat sources;  
For the cable terminals fixed using screw threads, the screws or nuts should be  
securely fastened and prevented from loosing. See the following figure;  
Figure 55 Cable fixing example  
Flat  
washer washer

Nut  
Verifying the Installation  
73  
When using a hard power cord, fix it near its terminal so as to free the terminal  
and the cable from stress;  
Do not use tapping screws to fasten the connecting terminals;  
The power cords of the same type and in the same direction should be bundled  
together and kept neatly and straight;  
The following table lists the requirements in the bundling with cable ties.

No cable or bundle can tie a knot;  
The metal parts of the crimped cold-pressed terminal blocks (such as air switch)  
cannot stretch beyond the blocks.  
Verifying the  
Installation  
CAUTION: Confirm that you have turned off the power before checking,  
otherwise, improper connection will hurt people or impair the components of the  
switch.

SWITCH MONITORING AND  
MAINTENANCE  
6
Monitoring the Switch Although the Switch 8800 Family has undergone a comprehensive factory test  
before delivery, an improper installation may cause problems. This chapter  
describes how to troubleshoot the Switch 8800 Family.  
Troubleshooting Console If the system running properly, when you power on the switch, you will see the  
Terminal boot information on the console terminal. If the switch is configured incorrectly,  
the console terminal may display illegible output or nothing at all.  
If the console does not display anything after you power on the switch, check that  
the:  
Power system is working normally.  
Fabric is working normally.  
Console cable is connected to the console port on the fabric.  
If you find no issues with these items, the problem is most likely one of the  
following:  
The console cable is not connected to the right serial port. That is, the port in  
use is not the one configured on the terminal.  
There are console terminal parameter errors. (According to the parameter  
setting requirements, you should set the baud rate to 9600, data bits to 8,  
parity to None, stop bits to 1, flow control to None, and select VT100 as your  
terminal emulation protocol.)  
The console cable is not in good condition.  
If the terminal displays illegible characters, it is most likely a console terminal  
setting error. Check that you have set the baud rate to 9600, data bits to 8, parity  
to None, stop bits to 1, flow control to None, and select VT100 as your terminal  
emulation protocol.

CHAPTER 6: SWITCH MONITORING AND MAINTENANCE  
The following PSU faults may appear on the switch. Follow the instructions  
provided to resolve the problem.  
Display Power Command Indicates the PSU is Not in Position  
The Input LED (green) and Output LED (green) stay ON, but the display power  
command shows that the PSU is not in position (but the other PSU operates  
normally). This problem is likely caused by a poor connection (badly seated)  
between the PSU and the backplane. To correct this:  
1 Switch off the power supply  
2 Loosen the screws on the PSU  
3 Push the PSU into the chassis a little bit  
4 Tighten the screws  
5 Switch on the power supply to check that the normal state is resumed  
The Input LED (green) and Output LED (green) are OFF  
Check that the power cords are connected correctly, the power cords are in good  
condition, and the power switch has been put in the ON position.  
The Fail LED (red) is ON  
Check that the:  
Correct power voltage is in use (90 to 264VAC, 50-60 Hz for AC PSU).  
Air filter protecting the fan tray is clean. Excessive dust accumulated on the air  
filter may block the fan tray from free ventilation and can lead to power supply  
failure.  
If the problem persists, contact 3Com technical support engineers. Do not  
disassemble the PSU yourself.

Upgrading software XModem is a file transfer protocol used for its simplicity and performance. It  
through console port transmits files through serial interfaces, supporting 128 bytes and 1Kbytes in data  
(XModem) units, checksum and CRC checking modes, and multiple transmissions attempts  
(usually 10 attempts) when packet errors are found.  
XModem completes the transmission by the receiving program (receiver) and the  
sending program (sender). In XModem, the transmission begins by sending  
negotiation characters from the receiver for the purpose of check mode  
negotiation. After passing the negotiation, the sender is allowed to send the first  
data packet. Upon receiving the complete packet, the receiver checks the packet  
using the agreed upon check mode and sends an ACK if the packet has passed  
the check and a NAK if it did not. After receiving the ACK, the sender sends the  
next packet; if it receives a NAK, the sender retransmits the previously sent packet.  
To run the Xmodem application:

Upgrading the Software Trivial File Transfer Protocol (TFTP) transmissions are initiated by the client. When  
Using TFTP downloading a file, the client sends a read request packet to the TFTP server,  
receives the data packets from the server, and sends the ACK to the server. When  
uploading a file, the client sends a write request packet to the TFTP server, then  
sends the data packets to the server, and receives the ACK from the server. The  
TFTP transmission files have two forms; binary for program transmission and ASCII  
for text transmission.  
To upgrade the software using TFTP perform the following steps.  
This procedure uses a Switch 8814 work as the TFTP client.  
n
1 Connect the switch to a PC where the file is located using the  
management/upgrade Ethernet port. (You need the IP address of the PC. At the  
same time, connect the switch to an external PC (that can be the same one that  
contains the file) using the console port.  
2 Run the TFTP server program on the PC connected to the management/upgrade  
Ethernet port and specify the path for upgrading the application files.

CHAPTER 6: SWITCH MONITORING AND MAINTENANCE  
CAUTION:  
c
You must reboot the switch using the reboot command to validate the host  
program. If Flash memory space is not enough, you can delete some of the  
program files in Flash after completing the Boot ROM loading. (3Com  
recommends that you delete the host program that is no longer in use.) Then  
upload the host program to the switch using FTP.  
Make sure that you have saved other the configuration before rebooting.  
Do not power the switch off during the loading process.  
The Boot ROM and host program loading process is now complete.  
Using TFTP  
Using the CLI to upgrade using TFTP is similar to using FTP. The only difference is  
that you use the tftp get command to download software to the switch. In this  
case, the switch can only be used as a TFTP client to download the software to its  
Flash memory from the TFTP server. Once the download is complete all remaining  
steps are the same.

Installing a Lightning  
Arrester for the AC  
Power  
This appendix describes how to install the lightning arrester for the AC power (a  
socket strip with lightning protection)  
CAUTION: A lightning arrester is not shipped with the switch. You must purchase  
it separately, if needed.  
c
Make sure, when connecting an outdoor AC power cord directly to the switch,  
that you connect a lightning arrester to the AC power (a socket strip with  
lightning protection) before you plug the AC power cord into the switch. This  
helps to prevent damage in the event of a lightning strike. Install your lightening  
arrester according to its manufacturers instructions.

After inserting the switch’s AC power cord plug into the lightening arrester’s  
socket, if the green LED is on and the red LED does not alarm, it means that the  
lightning arrester’s power is running and the lightning protection function is  
active.  
Make sure that the red LED is on. If there is a problem, determine if the  
arrester’s ground wire is well grounded and the live and zero wires are

CHAPTER A: LIGHTNING PROTECTION OF THE SWITCH  
connected in right direction. When the red LED is on, use a multimeter to  
examine the polarity at the arrester’s power socket. If it is same as that of the  
power socket in the equipment room, it means that the arrester is not well  
grounded. If it is adverse to that of the power socket in the equipment room, it  
means that the arrester’s power socket is set to the reverse polarity. In this case,  
you should open the arrester’s power socket and correct the polarity. After  
that, if the red LED still alarms, it means that the arrester is still not well  
grounded.  
Installing a Lightning  
Arrester for the  
Network Port  
A network port lightning arrester is specifically designed for an 10/100M electrical  
interface (an RJ-45 connector in this case) Ethernet port.  
n
Make sure, when connecting an outdoor AC power cord directly to the switch,  
that you connect a lightning arrester to the AC power (a socket strip with  
lightning protection) before you plug the AC power cord into the switch. This  
helps to prevent damage in the event of a lightning strike. Install your lightening  
arrester according to its manufacturers instructions.  
Required tools  
Phillips screwdriver or flat-module screwdriver  
Multimeter  
Tilted wire cutter  
Installation procedure  
1 Remove the protection paper from one side of the double-faced adhesive tape,  
and stick the tape to the surface of the arrester. Remove the protection paper from  
the other side, and stick the arrester onto the switchs chassis as close to the  
grounding screw as possible.  
2 Cut the arresters ground wire to the length of the distance between the arrester  
and the switchs grounding screw so that you can securely tighten the ground wire  
to the switchs grounding screw.  
3 Use the multimeter determine if the arresters ground wire connects properly  
chassiss grounding screw.  
4 According to the instructions provided with your network port arrester, connect  
the arrester to switch using the cables (Make sure to insert the outdoor network  
cable into the arrester‘s IN end, and the cable that is connected to the switch into  
the arresters OUT end). Check that the arresters indicators display correctly.  
5 Use the nylon ties to bundle the cables neatly.
