Replacing a TRSA CRU

Inspecting a TRSA CRU
Note: Whenever you handle a TRSA CRU, you should follow standard operating
practices to avoid damage to the equipment.
Visually inspect the new TRSA CRU and the backplane connector for damage. Use a
flashlight, if necessary, to check for bent or broken pins. You can damage pins by
bumping or jamming the TRSA CRU's shell against a surface, which can partially close
the hole in the connector-pin socket. If the TRSA CRU has a damaged connector-pin
socket, do not install it.
Caution: If you plug an TRSA CRU that has a damaged socket into a slot, that
TRSA CRU's backplane pins and the connectors on other adapter boards that are
plugged into that slot can be damaged. Moving a damaged board from slot to slot can
damage other slots and other adapter boards.
