Installing Modules
To install modules starting from slot 1 (the first open slot next to the
processor), follow the steps below:
1
For each 400EM tie line/trunk module, for jacks numbered 1 through 4 in
Figure 2-11, check Form 3c, incoming Trunks: Tie, for E&M signaling
type.
Set the dual in-line packaging (DIP) switches on the front of the 400EM Tie
Trunk module according to the E&M signaling type settings listed in Table 2-4
and Table 2–5 and shown in Figure 2–11. The default E&M signal does not
require any adjustments in the DIP switches.
2 Remove the protective cover from each module's gold-finger connector.
3 Lower the hook on top of the module onto the rod on the top of the
carrier in the appropriate slot. See Figure 2--10.
4 Make sure the connector on the module mates properly with the
connector on the carrier.
5
Swing the module into the slot and firmly push the module into the
carrier until it locks into place.
CAUTION:
To avoid damage, do not force the module. If the module does not insert
easily, press the bottom rear locking tab, remove the module, and
inspect the module and carrier for damage or obstruction.
If there is no damage and no obstruction, reinsert the module, A
damaged carrier or module must be replaced.
6 Repeat Steps 1 through 5 for each module you want to install.
