40 Installing Enclosure Components

Installing a Power Supply/Cooling Fan Module

1
Carefully slide the new power supply/cooling fan module approximately two-thirds of the way into the
empty bay.
2
Gently push the module all the way to the back of the bay until it is firmly seated in the backplane
connector.
The power supply is seated when its front plate is even with the front plate of the adjacent power
supply.
NOTE: If the enclosure is powered on, all power supply LEDs (see Figure1-8) remain off until you connect the
AC power cable to the power supply and turn on the on/off switch.
3
Tighten the two captive screws to secure the new power supply/cooling fan module in the bay.
4
Connect the AC power cable to the new power supply and to an electrical outlet.
5
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 enclosure cover and access any of the
components inside the enclosure. Before performing any procedure, see your
Product Information Guide
for
complete information about safety precautions, working inside the enclosure and protecting against
electrostatic discharge.

Removing the Control Panel

1
Power down your host server.
2
Power down your enclosure.
3
Disconnect all power cables to the enclosure.
4
Loosen the two thumbscrews on the front of the enclosure panel and pull the enclosure approximately
six inches out from the rack (see Figure3-8).
5
Remove all the drives from the enclosure (see "Removing and Installing Drives").
NOTE: To avoid confusion when re-installing the drives, mark each drive with its slot position as you remove it.
