Installing the Hardware

40 Enterasys Xpedition 2000 Getting Started Guide

To attach the segment cables to your Dual Serial or Quad Serial – C/CE expansion module:

1. Obtain one of the for Enterasys connector cables described in Table 19 on page 38 and connect

the single LFH-60 high density connector to the XP WAN interface you wish to use.

2. Plug the remote end of the connector for each port you wish to use into its respective

CSU/DSU data port.

Dual HSSI Line Card

The Dual HSSI line card uses a 50-pin High Speed Serial Interface (HSSI) connector to link to a

Channel Service Unit/Data Service Unit (CSU/DSU). Enterasys offers a 3 meter (10 foot) 50-pin

HSSI connector cable (part number SYS-HSSI-CAB) to connect Dual HSSI line cards to remote

CSU/DSU modules.

The following table maps the pin assignments for Enterasys’s 50-pin HSSI connector for the Dual

HSSI line card.

Note: Because neither connector at the ends of the SYS-HSSI-CAB cable is keyed, you can

simply plug either end of the cable into either your Dual HSSI line card or the remote

HSSI CSU/DSU data port.
