Removing and Installing the Cisco AS5350 Power Supply

The Cisco AS5350 universal gateway supports a single power supply or a redundant power supply. A

redundant power supply has two power connections and provides higher reliability and load balancing.

You can use the redundant power supply to:

• Manage your system with alarms and other management features.

• Provide higher reliability with a second built-in power supply connected to a second power source.

• Balance loads.

Note The redundant power supply on the Cisco AS5350 requires Cisco IOS Release 12.2(2)XB5 or later

release.

The following sections describe how to remove and install the Cisco AS5350 power supply:

Note Note that the power switch is part of the power supply.
