CPU/IO module in the next step.

Loosen the screws securing the CPU/IO module handle to press down the handle.
IMPORTANT:
Before you pull out a CPU/IO module, check the rear of the server to make sure cables for
connection with peripheral equipment or network are disconnected. If any cables are
connected, keep a record of where the cables are connected and disconnect all cables
connected to the module you are to pull out.
TIPS:
If you cannot disconnect the LAN cable easily, disconnect while pressing the latch with a
slotted screwdriver.
