Installing Enclosure Components 37

CAUTION: The power supply/cooling fan modules are heavy. Use both hands

when removing.

Press the release tab inward and grasp the handle on the power supply,

carefully pulling the module out of the bay (see Figure 3-6).

NOTICE: The power-supply handle is provided to ease the task of pulling the

module from the bay. Do not use this handle to carry the module, or use it to carry

the enclosure itself.

Installing a Power Supply/Cooling Fan Module

Carefully slide the new power supply/cooling fan module approximately

two-thirds of the way into the empty bay.

Gently push the module all the way to the back of the bay until it is firmly

seated in the backplane connector.

NOTE: If the enclosure is powered on, all power supply LEDs (see Figure 1-7)

remain off until you connect the AC power cable to the power supply and turn

on the on/off switch.

Connect the AC power cable to the new power supply and to an electrical

outlet.

Turn on the on/off switch on the new power supply.

Removing and Installing the Control Panel

The control panel powers the LED indicators on the front panel of the

system, as well as the Enclosure Mode Selection switch. It is connected to the

backplane and cannot be removed or replaced unless the system is powered

down.

CAUTION: Only trained service technicians are authorized to remove the system

cover and access any of the components inside the system. Before you begin this

procedure, review the safety instructions that came with the system.

Removing the Control Panel

Power down your host server.

Power down your enclosure.

Disconnect all power cables to the enclosure.
