Removing and Installing the Power Supply

The ASA 5545-X and 5555-X models ship with one power supply installed. You can add an additional
power supply, or you can order these appliances with two power supplies installed. Having two power
supplies installed provides a redundant power option. This configuration ensures that if one power
supply fails, the other power supply assumes the full load until the failed power supply is replaced. To
maintain airflow, an empty bay must be covered, or both bays must be populated with power supplies.
If only one power supply is installed, do not remove the power supply unless the appliance has been
powered off. Removing the only operational power supply causes an immediate power loss.
If you remove a power supply, replace it immediately to prevent disruption of service.
Caution
Caution If the appliance is subjected to environmental overheating, it shuts down and you must manually power
cycle the appliance.
Warning This unit has more than one power supply connection; all connections must be removed completely
to completely remove power from the unit. Statement 102
For DC power supplies, use an 80 VDC 20A fuse or circuit breaker on the input during installation.
Caution
To remove and install the power supply, follow these steps:
If you are adding an additional power supply, from the back of the appliance, push the lever on the slot

cover to the left to release it, grasp the handle of the slot cover and pull it away from the chassis. Save
