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).

shows how to plug your serial cable into a port on the Dual
Serial or Quad Serial – C/CE expansion modules.
Enterasys offers the following four cables, used to connect the XP to standard CSU/DSU modules:
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.

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.
