Power Supply Modules
There are two hot swappable power supplies per Base Unit cabinet enclosure. Each power
supply is capable of running the system independently and can be hot swapped with
another assembly at any time. Each power supply has three fans on its front panel to help
with system cooling.

Disk Drive Carriers
The system disk drives are enclosed in individual disk drive carriers 12 per enclosure.
Individual failed drives can be hot swapped while the system is running. In the default
RAID-5 configuration, a RAID-5 array will continue to function with slightly degraded
service in the event of a drive failure.
However, prompt action should be initiated to replace the failed drive. When a drive fails
in a fault tolerant RAID array, the arrays is put into a "critical" state where the failure of a
second drive in the array will lead to non-recoverable data loss. After the user replaces the
failed drive, the system administrator must initiate the RAID volume rebuild in the
background, a process which can take several hours.
