Replacing Components
• The replacement power supply must have the same wattage and airflow direction as the power supply
• An AC power source must be within reach of the power cable that will be used with the replacement
• There must be an earth ground connection to the chassis that you are installing the replacement module.
Step 1
Remove an AC power supply as follows:
a) Holding the plug for the power cable, pull the plug out from the power receptacle on the power supply and verify
that both power supply LEDs are off.
b) Grasp the power supply handle while pressing the colored release latch towards the power supply handle.
c) Place your other hand under the power supply to support it while you slide it out of the chassis.

Step 2
Install the replacement power supply as follows:
a) Holding the replacement power supply with one hand underneath the module and the other hand holding the handle,
turn the power supply so that its release latch is on the right side and align the back end of the power supply (the end
with the electrical connections) to the open power supply slot before carefully sliding the power supply all the way
into the slot until it clicks into place.
Note
b) Test the installation by trying to pull the power supply out of the slot without using the release latch.
If the power supply does not move out of place, it is secured in the slot. If the power supply moves, carefully press
it all the way into the slot until it clicks in place.
c) Attach the power cable to the electrical outlet on the front of the power supply.
d) Make sure that the other end of the power cable is attached to the appropriate power source for the power supply.

power supply. If you are using n+n power redundancy, there must be a separate power source for each
power supply installed in the chassis.
AC power supplies connected to AC power sources are automatically grounded through their power
cable.
Do not touch the electrical connections on the back side of the module and prevent anything else from
coming into contact with and damaging the connectors.
If the power supply does not fit into the open slot, turn the module over before sliding it carefully into
the open slot.
Depending on the outlet receptacle on your power distribution unit, you might need the optional jumper
cable to connect the switch to your outlet receptacle.
