Installing and Removing the System Bus Adapter (SBA) Cable

Assembly

The SBA Cable Assembly terminates in the SEU on the System Backplane, located in the left side of the

chassis, and travels out of the SEU to the host server. All system power must be removed before attempting to

install or remove this component.

NOTE The figures depicting SBA cables, mounting hardware, and receptacles may differ from the

appearance of the actual cables and receptacles that you receive. The procedures listed for

installation and removal should remain essentially the same, however.

CAUTION Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD

safety precautions could result in damage to the SEU.
