Redundant Power Supply

The Compaq RA4100 includes a second power supply, which acts as a
redundant supply. The redundant power supply is identical to the primary
supply and shares the electrical load equally. If either supply fails or is
removed, the other supply takes over the full load without interruption. Hot-
pluggability allows you to replace the failed supply without shutting the
system down. See Chapter 4, "Replacing a Redundant Power Supply" for
more information.
