Cat4500 power supplies

Hi there,

can anybody tell me whether the power supplies in Cat4500 are hot swappable?

Hi,

the power suplies are hot swappable, but you have two possible modes:

The Catalyst 4500 series switches support two power management modes:

Redundant mode:Redundant mode uses one power supply as a primary power supply and the second power supply as a back-up. If the primary power supply fails, the second power supply immediately supports the switch without any disruption in the network. Both power supplies must be the same wattage. A single power supply must have enough power to support the switch configuration.

Combined mode:Combined mode uses the power from all installed power supplies to support the switch configuration power requirements. However, combined mode has no power redundancy. If a power supply fails, one or more modules might shut down.

By default, a switch is set to redundant mode. In the show power command, if the power supplies needed by system is 1, the switch is in redundant mode; if the power supplies needed by system is 2, the switch is in combined mode.
