Disengage the latch on the power supply and pull it from its slot so that the backplane pins are not
connected.
Hardware shutdown
Graceful shutdown
You will need a pen or small screwdriver for these procedures.
1 Using a small tool, press the recessed shutdown button until the "Complete" LED starts to flash
on the TN2314 processor circuit pack.
