Power Sources
Power Sources
Your unit operates with the following power sources:

Replaceable power supply module (either AC or DC). Your unit needs
only one power supply module to work, but it can house two of them.
The second power supply provides redundancy. Your unit has been
certified with two power supplies of the same type (two AC or two DC).
The power supply modules are hot-swappable, which means that you
do not have to turn off your system to replace one of them. There is no
need to disassemble the unit to replace such a power supply. For more
information, see Replacing the Power Supply Modules on page 257.

Rechargeable battery (for clock). This battery can keep the date and
time for a very long time even if power is not connected to the unit.
