5 To engage the module connectors into the chassis backplane connectors,
push both module ejector handles simultaneously inwards toward the
front panel, locking the module (Figure 42). You feel a slight resistance as
the connectors engage.
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.

the left and right of the ATM Interface Module (Figure 43).
