CHAPTER 2
NETWORK REQUIREMENTS
This chapter contains general networking guidelines. Before attempting
to use the 8H02-16 or to install a Fast Ethernet Interface Module
(FE-100TX or FE-100FX), review the requirements and specifications
outlined in this chapter.
2.1
NETWORK REQUIREMENTS
The network installation must meet the guidelines included in this chapter
to ensure satisfactory performance of this equipment. Failure to follow
these guidelines may produce poor network performance.
Refer to the following sections that apply to your specific network
configuration.
2.1.1
10BASE-T Twisted Pair Network
When connecting a 10BASE-T twisted pair segment to any of the
8H02-16 ports (Interfaces 1 through 14), ensure the network meets the
following requirements:
Length
The IEEE 802.3 standard for 10BASE-T requires that 10BASE-T devices
transmit over a 100 meter (328 foot) link using 22–24 AWG Unshielded
Twisted Pair (UTP) wire. However, cable quality largely determines
maximum link length. If you use high quality, low attenuation cable, you
can achieve link lengths of up to 200 meters. Cable delay limits the
maximum link length to 200 meters.
Losses introduced by connections at punch-down blocks and
other equipment reduce total segment length. For each
NOTE
connector or patch panel in the link, subtract 12 meters from
the total length of the cable.

Chapter 2: Network Requirements
Impedance
Cabletron Systems 10BASE-T twisted pair products work on twisted pair
cable with 75 to 165 ohms impedance. UTP cables typically have an
impedance from 85 to 110 ohms. Shielded twisted pair cables, such as
IBM Type 1 cable with an impedance of 150 ohms may also be used.
Temperature
Multi-pair PVC 24 AWG telephone cables typically have an attenuation
of approximately 8–10 dB/100 m at 20°C (68°F). The attenuation of PVC
insulated cable varies significantly with temperature. At temperatures
greater than 40°C (104°F), use plenum-rated cable to ensure that
attenuation remains within specification.
2.1.2
100BASE-TX Twisted Pair Network
The 8H02-16 with an FE-100TX installed in ports 15 or 16 provides an
RJ45 connection that supports UTP cabling. The device at the other end
of the twisted pair segment must meet IEEE 802.3u 100BASE-TX
specifications for the devices to operate at 100 Mbps. Use Category 5
UTP cabling for networks operating at 100 Mbps. Use Category 3, 4, or 5
UTP cabling for networks operating at 10 Mbps.
The 8H02-16 with an FE-100TX installed is capable of
operating at either 10 or 100 Mbps. The FE-100TX senses the
NOTE
speed of the other device and adjusts its speed accordingly.
When connecting a 100BASE-TX twisted pair segment to port 15 or 16
with an FE-100TX interface module, the network must meet the
following requirements:
Length
The IEEE 802.3u standard for 100BASE-TX requires that 100BASE-TX
devices be capable of transmitting over a 100 meter (328 foot) link using
Category 5 UTP cable.
The IEEE 802.3 standard for 10BASE-T requires that 10BASE-T devices
be capable of transmitting over a 100 meter (328 foot) link using
Category 3, 4, or 5 UTP cable.

Network Requirements
Propagation Delay
Propagation delay is the amount of time it takes data to travel from the
sending device to the receiving device.
Total propagation delay allowed for a 100BASE-TX (100 Mbps) network
is 256 bit times or 2.56 microseconds (2.56 µs). If the total propagation
delay between any two nodes on a 100BASE-TX network exceeds
2.56 µs, then use bridges or other devices to further segment the network.
Total propagation delay allowed for a 10BASE-T (10 Mbps) network is
256 bit times or 25.6 µs. If the total propagation delay between any two
nodes on a 10BASE-T network exceeds 25.6 µs, then use bridges or other
devices to further segment the network.
Temperature
The attenuation of PVC insulated cable varies significantly with
temperature. At temperatures greater than 40°C (104°F), use plenum rated
cables to ensure that cable attenuation remains within specification.
2.1.3
100BASE-FX Fiber Optic Network
Ports 15 and 16 of the 8H02-16 support the Cabletron Systems FE-100FX
fiber optic interface module. The FE-100FX meets the IEEE 802.3u
standard. When connecting a fiber optic segment to the 8H02-16, the
network must meet the following requirements:
Cable Loss
Test the fiber optic cable with a fiber optic attenuation test set adjusted for
an 850 nm wavelength. This test verifies that the signal loss is within an
acceptable level. The maximum loss for a multimode cable is 11.0 dB.
Fiber Optic Budget and Propagation Delay
Determine the maximum fiber optic cable length by calculating the fiber
optic budget delay and total network propagation before fiber optic cable
runs are incorporated in any network design.
Fiber optic budget is the combination of the optical loss due to the fiber
optic cable, in-line splices, and fiber optic connectors.

Chapter 2: Network Requirements
Propagation delay (collision delay) is the amount of time it takes data to
travel from the sending device to the receiving device. Total propagation
delay allowed for the entire network is 256 bit times (2.56 µs). If the total
propagation delay between any two nodes on the network exceeds
2.56 µs, then use bridges or other devices to further segment the network.
2.2
100BASE-TX NETWORK CABLE LENGTHS
This section details the maximum network cable lengths specified by the
IEEE 802.3u standard. As stated in the previous sections, the physical size
of the network is limited primarily by propagation delay. The total
propagation delay cannot exceed 256 bit times or 2.56 µs.
A 100BASE-TX/FX network might use all copper (UTP) links, all fiber
links or a combination of both. The maximum length of any segment is
determined by the types and combination of links and by the type of
repeater (if any) between segments. IEEE 802.3u standards specify two
repeater classes (Class 1 and Class 2) and the maximum cable lengths for
each media type.
If this device is being installed in a 100BASE-TX/FX environment with
repeaters, use the repeater instruction manual to determine the maximum
cable lengths when laying out your network.
UTP Maximum Cable Lengths
An Unshielded Twisted Pair copper segment in a 100BASE-TX
environment may be no more than 100 meters in length.
The maximum length of a UTP segment may be no more than
100 meters.
!
CAUTION
Multimode Fiber Cable Lengths
The maximum length of a 100BASE-FX segment may be no more than
412 meters between Data Terminal Equipment (DTE to DTE) in half
duplex mode or 2 km (DTE to DTE) in full duplex mode.

RUNTIME IP ADDRESS DISCOVERY
Upon power up, the 8H02-16, through a function called Runtime IP
Address Discovery, sends out a RARP and BootP request over the
network to determine its IP address. This function allows the loading of
an IP address into NVRAM on the 8H02-16 without using Local
Management. For information on setting up a workstation to act as a
server to respond to a RARP or BootP request, refer to the specific
workstation documentation.

The following briefly explains each field of the High Speed Interface
Configuration screen.
Port Type (Read-only)
Displays the name of the interface (FE-100FX or FE-100TX) installed in
ports 15 and 16. Figure 6-13 shows that there is an FE-100TX interface
installed in Port 15 and no interface [N/A] in Port 16.
Link Status (Read-only)
Indicates whether or not there is a physical connection from this port to
another 10BASE-T or 100BASE-TX/FX device. One of the following
values appears:
•
Link – There is a 10BASE-T or 100BASE-TX/FX link signal present;
there is a valid physical connection from this port to another
10BASE-T or 100BASE-TX/FX device.
•
No Link – There is no 10BASE-T or 100BASE-TX/FX link signal
present; there is no valid physical connection from this port to another
10BASE-T or 100BASE-TX/FX device.
Current Operational Mode (Read-only)
This field displays the current operating mode of ports 15 and 16.
Depending on whether a 100Base-FX or 100Base-TX is installed, this
field displays the following:
•
With a 100Base-FX interface: 100Base-FX or 100Base-FXFD (full
duplex)
•
(full duplex), 100Base-TX, or 100Base-TXFD (full duplex).
Desired Operational Mode (Selectable)
This field allows the user to select the desired operational mode for an
interface in port 15 or 16. The field toggles between 100Base-FX and
100Base-FXFD (full duplex) when an FE-100FX is installed.
Section 6.14.1 describes how to configure a port with an FE-100FX.

High Speed Interface Configuration Screen
In normal operation, the port with an FE-100TX installed
automatically establishes a link with the device at the other end
of the segment without requiring user setup. However, Local
Management provides the user with the option of manually
configuring that port.
NOTE
If an FE-100TX is installed, the field steps to Auto-Negotiation,
10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD
(full duplex). In normal operation, the port with an FE-100TX installed is
capable of auto-negotiating the operational mode and no further user
setup is required. Section 6.14.3 describes how to configure an
FE-100TX.
Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX “tells” the device at the other end
of the segment what its capabilities are. The capabilities of a port (15 or
16) with an FE-100TX installed are 10Base-T, 10Base-TFD (full duplex
mode), 100Base-TX and 100Base-TXFD (full duplex mode). In normal
operation, with all capabilities enabled, the FE-100TX “advertises” that it
has the ability to operate in any mode. The Network Manager may choose
to set up the port so that only a portion of the available capabilities are
advertised and the others are disabled. For example, only 100Base-TX
100 Mbps can communicate with that port.
6.14.1 Configuring an FE-100FX in Port 15 or 16
When an FE-100FX is installed in port 15 or 16, it must be manually set
to operate in the same technology as the device at the other end of the
connected segment. Section 6.14.2 provides instructions for manually
configuring the port with an FE-100FX interface.

6.14.3 Configuring an FE-100TX in Port 15 or 16
In normal operation, a port (15 or 16) with an FE-100TX interface
automatically establishes a link with the device at the other end of the
segment and no user setup is required. Section 6.14.4 and Section 6.14.5
provide instructions for manually configuring the port with an FE-100TX
installed.
6.14.4 Setting the FE-100TX Operational Mode
Use this field to set the active technology. This field steps between
Auto-Negotiation, 10Base-T, 10Base-TFD (full duplex), 100Base-TX,
and 100Base-TXFD (full duplex). If Auto-Negotiation is selected, the
FE-100TX automatically sets the active technology. To manually set the
active technology through Local Management, proceed as follows:
1. Use the arrow keys to highlight the Desired Operational Mode field.
2. Use the SPACE bar to select the desired mode. Press ENTER. If any
mode other than Auto-Negotiation is selected, the port only operates
in the chosen mode and auto-negotiation is disabled.

6.14.5 Setting the FE-100TX Advertised Ability
In normal operation, a port (15 or 16) with an FE-100TX auto-negotiates
to the highest speed possible. Under some circumstances, the Network
Administrator may want the port to advertise only some of the available
modes and not operate in other modes. This field steps between 10Base-T,
10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD (full
duplex). To set the advertised ability, proceed as follows:

•
Switch 6 - Forced Download. Changing the position of this switch
(i.e., moving the switch from one position to the other) clears
download information from NVRAM and forces the 8H02-16 to
download a new image file from a BootP server.
After changing the position of switch 6, DO NOT reapply power
to the 8H02-16 until there is a station acting as a BootP server,
which contains the image file.
NOTE
After changing the position of switch 6 and restarting the 8H02-16, the
8H02-16 requests a new image download until it either receives a new
image or the RESET button on the front panel is pressed. When the
RESET button is pressed, the 8H02-16 continues trying to contact a
BootP server, but will time out in approximately one minute. If the
8H02-16 times out, the image is downloaded from its FLASH memory.
•
Switch 7 - Clear NVRAM. Changing the position of this switch resets
NVRAM on either the next power up or the next operation of the front
panel RESET switch. All user-entered parameters such as the IP
address and Community Names are replaced with the 8H02-16
“Default” configuration settings.
•
Switch 8 - Password Defaults. Changing the position of this switch
clears user-entered passwords stored in NVRAM, and restores the
default passwords. Once the 8H02-16 is reset, the passwords can either
be reentered or the default passwords (Public and ENTER or
RETURN) may be used.
Do not change the position of switch 8 unless it is necessary to
reset the 8H02-16 Super-User configured passwords to their
factory default settings.
