Installing Enclosure Components
Removing and Installing the Control Panel
The control panel powers the LED indicators on the front panel of the system enclosure. 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 Figure 4-7).
5 Remove all the physical disks from the enclosure (see "Removing and Installing Physical Disks" on
page 56).
NOTE:
To avoid confusion when re-installing the disks, mark each one with its slot position as you remove it.
