Dual Serial And Quad Serial - C/Ce Expansion Modules - Enterasys X-Pedition 2000 Getting Started Manual

Installing the Hardware
Dual Serial and Quad Serial – C/CE Expansion Modules
The Dual Serial and Quad Serial – C/CE expansion modules each use the same 60-pin LFH-60
high density connector to link to their respective Channel Service Units/Data Service Units
(CSU/DSUs).
Serial or Quad Serial – C/CE expansion modules.
Enterasys offers the following four cables, used to connect the XP to standard CSU/DSU modules:

a. The two remote ends of each type of connector cable is labeled "Port A" and "Port B". "Port A" corresponds to
Port 1 on a Dual Serial WAN expansion module and Port 1 or 3 on a
Quad Serial – C/CE, depending upon which WAN expansion module port you are using. Similarly, "Port B"
corresponds to Port 2 on a Dual Serial WAN expansion module and Port 2 or 4 on a Quad Serial – C/CE.
Note: Because the LFH-60 high density connectors on Dual Serial and Quad
Serial – C/CE expansion modules contain two serial WAN ports per interface, all four
cable types defined above feed two CSU/DSU ports.
Table 20 maps the pin assignments for Enterasys' LFH-60 high density connectors for the Dual
Serial and Quad Serial – C/CE expansion modules.
