6 Install the supplied large ferrite chokes on the DSL and POTS cables as 

close as possible to the connectors. If necessary, use cables ties to hold the 

chokes in place.

7 Secure the cables as required for strain relief.

There are two Ethernet interfaces on the faceplate of the DSLAM, only one of 
which may be used at a time:

z

An 8-position modular jack providing support for 1000BaseT

z

A Small Form-Factor Pluggable (SFP) socket providing, with the 

appropriate transceiver installed, support for 1000BaseX and 1000BaseT. 

See 

Either interface can be used as the uplink for a single DSLAM, or for the 
terminating unit in a stack of DSLAMs.

To use the SFP connector or 10/100/1000 connector:

1 Connect the uplink cable to the DSLAM:

— For a wire connection, plug the 8-position modular plug of your 

uplink cable into the 10/100/1000 modular jack. A straight-through 

cable can be used regardless of the destination interface, since the 

port automatically distinguishes between a Medium-Dependent 

Interface (MDI) and an MDI Crossover (MDIX).
Install the supplied small ferrite choke on the cable as close as 

possible to the jack. Use a cable tie to hold the choke in place.
