Chapter 1Installation

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 Appendix A, “HSSI Module

Components.”

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 pre vent this, follo w 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.
