Hot-Pluggability

Hot-pluggability refers to the ability to remove and replace components
without powering down the system. There are four components in the Compaq
RA4100 that are considered hot-pluggable:
Hard Drives—Failed hot-pluggable drives in RAID 1, 4, and 5 configurations
can be replaced without interrupting system operation. Data on the failed drive
is restored automatically on the replacement drive online.
Fan Assembly—If one of the cooling fans in the assembly fails (indicated by
an amber fan LED), the fan assembly can be removed and replaced. The fan
assembly must be replaced within five minutes of removal to ensure system
operation continues without interruption.
Power supply—The redundant power supply allows you to remove either
power supply and replace it without interrupting system operation.
