communications connections on the back of the module join connectors on the
backplane. Use the module ejectors on the left side of the module to lock the
module in place.

should slide in with minimal force.

the module until they lock. When the levers are locked, the power and
communications connections at the rear of the module mates with the
communications connectors at the rear of the chassis slot.
