Replacing a Power Supply
The AS3000 is designed to run with two operating power supplies. A power supply can be
replaced if it fails. If a power supply fails, the LED on the power supply and the front panel LED
turn red and a beeping alarm sounds. The alarm is not configurable.

A power supply is only hot-swappable if the other power supply is operational. If you only
have one power supply working, before removing or replacing that power supply, you must
first take the server out of service, turn off all peripheral devices connected to the system,
turn off the server by powering it off from the Start menu. Then unplug the AC power cord
from the system or AC outlet.

Avid recommends the use of uninterruptible power supplies, appropriately sized for your
AS3000. This provides protection against sudden power surges or losses that could cause
you to lose files or experience data corruption. See “Uninterruptible Power Supply (UPS)”
on page 68.
