BeforeYou Begin
This guide describes how to install, cable, maintain, and troubleshoot the High-Speed Serial
Interface (HSSI) module for the NETBuilder II
®
base system. The information in this guide
applies to the NETBuilder II 4-slot chassis and the NETBuilder II 8-slot chassis.
For more information about the NETBuilder II base system installation, refer to the
NETBuilder II Base System Installation Guide
.
This guide is intended for the system administrator, network equipment installer, or network
manager who is responsible for installing and managing the network hardware. It assumes a
working knowledge of network operations, but it does not assume prior knowledge of 3Com
internetworking equipment.
NOTE:
If the information in the release note shipped with your software differs from the
information in this guide, follow the release note.
How to UseThis Guide
The following list shows where to find specific information. Refer to the documentation
roadmap in the front of this manual for information on related manuals.

Chapter 1
Installation
This chapter describes how to install the HSSI module into the NETBuilder II
®
base system.
The HSSI module provides a single serial interface for a WAN connection in the NETBuilder II
base system. It supports transmission rates up to OC1, including E3, T3, and sub-rates.
NOTE:
The HSSI module must be used with NETBuilder II HSSI and Single-Mode FDDI
Software 6.2. For information about the software, see the
NETBuilder II HSSI and Single-
Mode FDDI Software 6.2 Release Notes
.
For information about the HSSI module components, refer to AppendixA, “HSSI Module
Components.”
Before Installing the HSSI Module
Before you install the HSSI module into the NETBuilder II base system, follow these steps:
1. Observe appropriate ESD precautions.
Electrostatic discharge (ESD) can damage circuit board components. Failures resulting
from ESD may not be covered under your warranty. To prevent this, follow these handling
procedures:
■
Keep the HSSI module in its antistatic shielded bag until you are ready to install it.
■
Do not touch pins, leads, or solder connections on the board.
■
Handle the board by the edges only.
■
Store or ship the HSSI module in static-protective packaging.
Observe proper grounding techniques when handling the HSSI module: Use a foot strap
and grounded mat, or wear a grounded static discharge wrist strap.
2. Inspect the HSSI module for shipping damage.
If you find any damage, contact the shipping company to file a report. If the assembly
must be returned to your network supplier, ship it in its original shipping carton. If the
original carton was damaged in shipment, repack the system in a carton that provides
equivalent protection.

3. Verify that you have received all the contents.
When you purchase the HSSI module, you receive the following:

NETBuilder II HSSI Module Installation Guide
If an item is missing from an undamaged carton, contact your network supplier to secure a
replacement.
4. Write down the serial number and the MAC address from the label on the
component side of the HSSI module on the following line:
Serial number example: S/N:1BK12345
MAC address example: 0800021A4B5C
You will need this information if you have to contact your network supplier.
The MAC address is also encoded in the HSSI module’s EEPROM. Use the procedure in
Appendix B, “Displaying the MAC Address,” to display the MAC address encoded in the
EEPROM.

Installing the HSSI Module
Installing the HSSI Module
Use this procedure to install the HSSI module into the NETBuilder II base system.You will
need a small flathead screwdriver.
NOTE:
There are two versions of the NETBuilder II 4-slot and 8-slot chassis. The older, single-
wide versions of the NETBuilder II 4-slot and 8-slot chassis have two flipper ejectors for each
module. The newer, dual-wide versions have one flipper ejector for each module, except for the
top slot which is reserved for the CEC module. When the term “dual-wide NETBuilder II
chassis” is used in this manual, it refers to a chassis with only one flipper ejector per module.
1. Select an I/O slot in which to install the HSSI module.
You can install the module in any available I/O slot in the rear of the NETBuilder II base
system. The top slot is designated for the CEC module only.
2. Remove the blanking plate from the I/O slot you have selected for the HSSI module.
CAUTION:
Only remove the blanking plate from an I/O slot that will house an I/O module. All
unused I/O slots require blanking plate covers to maintain proper cooling of the unit and
regulatory compliance. Failure to cover open slots can result in overheating of the NETBuilder
II base system and voiding of the warranty.

3. Insert the HSSI module into an uncovered I/O slot.
Make sure the flipper ejector(s) are in an open position.
With the connector end toward the backplane and the board facing up (check that the
labels on the connector/LED panel are right side up), grasp the left and right sides of the
panel and fit the board into the I/O slot opening along the guide rails.
4. Lock the board in the slot.
For the dual-wide NETBuilder II chassis, use your thumbs to push the board all the way
into the slot. As you slide the board into the slot, the flipper ejector engages itself. For
single-wide NETBuilder II chassis, push the flipper ejector closed.
5. Check that the connector/LED panel of the newly inserted module is flush with the
NETBuilder II chassis.
To verify that the board is seated correctly, check that it is aligned with the connector/LED
panel of an installed module.
6. Hand tighten the captive screws. Do not use a screwdriver.
A solid connection of the connector/LED panel to the chassis is required for proper
operation. Do
not
use the screws to force the board into place.

Installing the HSSI Module
Cabling the HSSI Module for Network Connection
A SCSI-type cable connects the HSSI Module DTE connector to a Data Service Unit (DSU).
Table 1-1 describes the connectors. Table 1-2 describes the pin assignments.
3Com recommends using minimum lengths of this cable, especially if you plan to use these
serial lines at high speeds. The maximum cable length allowed is 50 feet.
To connect the HSSI module to the network, insert a SCSI type cable into the female connector
in the rear of the HSSI module

Installing the HSSI Module
CAUTION:
Connections between 3Com equipment and other equipment and peripherals must
be made using shielded cables in order to maintain compliance with FCC, and other agency
radio frequency emissions limits. All interconnection cables should be equipped with shielded
connectors. The backshells of these connectors must completely surround the cable shield.
Internal Loopback test
An internal loopback test is performed automatically when you insert the HSSI module into the
NETBuilder II chassis. A successful loopback test is indicated by the following example
