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.
