Figure 36 Locking the Module Ejector Handles
CAUTION: If the resistance is too great, the ATM Interface Module
connectors and backplane connectors may not be aligned. Forcing the
ATM Interface Module inward can damage the module connectors or
backplane connectors. If necessary, remove and reinsert the ATM
Interface Module, ensuring that the connectors are properly aligned. Do
not tighten the captive screws to seat the module.
6 Using the #2 flat-blade screwdriver, once the module is seated, tighten
the two screws located on the top and bottom of the ATM Interface
Module (Figure 37).
