Replacing an E4SA CRU

Inspecting an E4SA CRU
Note: Whenever you handle an Ethernet 4 ServerNet adapter (E4SA) CRU, you
should follow standard operating practices to avoid damage to the equipment.
Visually inspect the new E4SA 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 E4SA CRU's shell against a surface, which can partially close
the hole in the connector-pin socket. If the E4SA CRU has a damaged connector-pin
socket, do not install it.
Caution: If you plug an E4SA CRU that has a damaged socket into a slot, that
E4SA 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.
