Removing and Replacing the Midplane Board
The midplane board is attached to the main bulkhead in the center of the chassis. It provides a
connection between the power supplies, the I/O board assembly, and the processor board
assembly.
WARNING! Ensure that the system is powered off and all power sources have been disconnected
from the server prior to performing this procedure.
Voltages are present at various locations within the server whenever an AC power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions can result in damage to the server.
