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.  
8H02-16 User’s Guide  
2-1  
 
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.

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.  
8H02-16 User’s Guide  
2-3  
 
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.

3.5.2  
Connecting a UTP Segment to the FE-100TX  
An FE-100-TX installed in port slot 15 and/or 16 is often used to provide  
a connection between the 8H02-16 and a bridge, router, or switch.  
Usually, in this configuration, a “straight-through” cable is used and the  
Fast Ethernet Interface Module crossover switch shown in Figure 3-7 is  
set to “not crossed over.”  
Normally, when connecting devices to like devices, crossing over of the  
transmit and receive pairs must occur. Before connecting a segment to the  
FE-100TX, check each end of the segment to determine if the wires have  
been crossed over for the proper connection.  
A schematic of a crossover cable is shown in Figure 3-6. If the wires do  
not cross over, use the switch on the FE-100TX to internally cross over  
the RJ45 port. Figure 3-7 shows how to properly set the FE-100TX  
crossover switch.

Systems supplies fiber optic cable that uses SC style connectors that are  
keyed to ensure proper crossing over of the transmit and receive fibers.  
An odd number of crossovers (preferably one) must be  
maintained between devices so that the transmit port of one  
device is connected to the receive port of the other device and  
vice versa.  
!
CAUTION  
If the fiber optic cable being used has SC style connectors that  
do not resemble MIC style connectors, or has SC connectors  
on one end and a different type on the other, such as ST  
connectors, ensure that the proper crossing over occurs.

CONNECTING A MANAGEMENT TERMINAL TO  
THE 8H02-16  
The 8H02-16 comes with a Console Cable Kit that provides a cable and  
RJ45-to-DB9 adapter. The adapter allows the 8H02-16 RJ45 COM port to  
connect to an IBM or compatible PC running a VT series emulation  
software package. For detailed instructions regarding the connection of  
the console cable to the 8H02-16, refer to the instruction sheet provided in  
the Console Cable Kit.  
Optional adapters are available to connect the 8H02-16 to Local  
Management through a VT type terminal or a modem. Refer to the RJ45  
Console Cable Kit Instruction Sheet for installation instructions and  
adapter specifications.  
5.4  
CONNECTING THE UPS TO THE 8H02-16  
The following hardware is needed to connect the 8H02-16 to the UPS:  
An RJ45 console cable  
An RJ45 to DB9 adapter  
To connect a cable from the UPS to the 8H02-16 COM port, perform the  
following steps:  
2. Plug the other end of the console cable into the adapter and connect the  
adapter to the UPS.  
With the cable connection complete and with a valid IP address entered  
into the 8H02-16 through Local Management (see Chapter 6) or through  
Runtime IP Address Discovery (refer to Section 5.5, Runtime IP  
Address Discovery), use one of the following management tools to  
configure the 8H02-16 COM port for the UPS application:

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.

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)  
With a 100Base-TX interface: Unknown, 10Base-T, 10Base-TFD  
(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.  
6-40  
8H02-16 User’s Guide  
 
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

6.21.1 Built-in Commands  
The built-in commands listed in this section activate functions on the LM  
managed device or devices being accessed through MIB Navigation.  
arp:  
Syntax:  
arp <options>  
Description:  
The arp command provides access to the ARP  
(Address Resolution Protocol) cache, enabling  
you to view cache data, delete entries, or add a  
static route. Super-User access is required to  
delete an entry or add a static route.  
Each ARP cache entry lists the network  
interface that the device is connected to, the  
device’s network address or IP address, the  
device’s physical address or MAC address, and  
the media type of connection to the device.  
Media types are displayed as numbers, which  
stand for the following states:  
1 - Other  
2 - Invalid entry (cannot ping device, timed out,  
etc.)  
3 - Dynamic route entry  
4 - Static route entry (not subject to change)

You can specify the arp command without options, or with one of the  
following options:  
Options:  
-a View cache data  
-d Delete an IP address entry. Requires  
additional arguments: <Interface Number> <IP  
address>  
-s Adds a static entry. Requires additional

Setting the Mode Switch  
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
