Maintenance and Upgrade Procedures

Removing and Installing the Power Supply Module

DC Power Supply Module

The ASA 5585-X ships with two DC power-supply modules installed in a load balancing/sharing

configuration. This is the only supported DC power-supply module configuration. The load

balancing/sharing configuration ensures that if one DC power supply module fails, the other DC power

supply module assumes the full load until the failed power-supply module is replaced. To maintain air

flow, both bays must be populated by two DC power-supply modules.

You can install or replace either power-supply module without powering off the appliance, as long as

one power-supply module is active and functioning correctly.

Only the ASA 5585-X SSP-60 supports either two AC or two DC power-supply modules. Do not mix

Note

AC and DC power-supply modules in the same chassis.
