Installing And Removing Primary Rate Modules - Alcatel MainStreet 2902 Manual

5.3

Installing and removing primary rate modules

Each primary rate module has a female connector that fits onto a male connector on
the Control card. The modules are secured to mounting posts on the Control card
with screws. The holes in the module should line up with the posts. If they do not,
you are installing the module in the wrong location.
There are two jumper blocks for each primary rate module on the Control card. The
jumpers need to be configured for E1 G.703 and E1 HDSL LIMs. The jumper
configurations do not affect operations for other primary rate modules.
Procedure 5-2 To install E1 G.703 or E1 HDSL LIMs
You need a #2 Phillips screwdriver to install E1 G.703 or E1 HDSL LIMs.
