Replacing The System Backplane - IBM Power System 9040-MR9 Manual

Replacing the system backplane in the 9040-MR9
To replace the system backplane, complete the steps in this procedure.
Procedure
1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged
into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Install the new system backplane.
a) Open the packaging for the new system backplane and place it on an appropriate ESD surface.
b) Grasp the new system backplane by the front (A) or middle (B) metal bulkheads and the rear
metal bulkhead (C). As you lower the backplane straight down into the chassis, take care to
ensure that the pins on the bottom of the backplane align with the holes in the chassis.
