Replace an M-300 or M-700 Appliance Power Supply
Learn how to replace a power supply on an M-300 or M-700
appliance.
M-300 and M-700 appliances have two AC power
supplies (the second power supply is for redundancy). If one power
supply fails, you can replace it without service interruption as
described in the following procedure.
Identify the failed power supply by viewing the
power supply LED on the back of the appliance; when there is a failure,
the LED turns solid yellow or turns off. The front panel system
information LED also blinks red.
Disconnect the power cord from the failed power supply.
Grasp the handle on the failed power supply and simultaneously press
the release lever to the left and then pull the power supply outward
to remove it.
Remove the replacement power supply from the packaging
and slide it in to the empty power supply slot. Push the power supply
all the way in until the release lever clicks and secures the power
supply.
Connect the AC power cord to the power supply input.
The power supply LED turns green and the front system information
LED stops blinking red.
