6.3.4 Installing and removing an extension board
Before you install or remove an extension board, shutdown the OS, unplug the power cord, and
wait for at least one minute. Installing or removing an extension board without shutting down the
power might result in an electric shock or a fire.
Disconnect all external cables connected to the equipment before installing or removing an
extension board. Not doing so might result in equipment failure.
