•
There must be an earth ground connection to the chassis that you are installing the replacement module.
To ground the chassis, see
Grounding the Chassis, on page 21
.
Step 1
If the power supply slot has a blank filler panel, remove it from the slot by moving its release latch to the left and pulling
the panel out of the slot.
Step 2
Holding the replacement power supply with one hand underneath the module and the other hand holding the handle,
align the back end of the power supply (the end with the electrical connections) to the open power supply slot and slide
the power supply all the way into the slot until it clicks into place.
Step 3
If the DC power cables and a grounding cable are already connected to an electrical connector block, insert the block
into the power receptacle on the power supply.
If the electrical cables have not been connected to the electrical connector block, wire them as described in
V DC Electrical Connector Block, on page 41
.
Step 4
Turn on the circuit breaker for the DC power source connected to the power supply.
Step 5
Verify that the power supply
LED turns on and becomes green.
Installing an AC Power Supply
Before You Begin
•
The power supply that you are installing must be capable of using the same airflow direction as the fan
trays installed in the same switch
•
An AC power source must be within reach of the power cable that will be used with the replacement
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. Otherwise, only one power source is required.

the power supply all the way into the slot until it clicks into place.
Step 3
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.
Step 4
Attach the power cable to the electrical outlet on the front of the power supply.
Step 5
Connect the other end of the power cable to an AC power source if it is not already connected to a power source.

For no power redundancy, connect one power supply to one power source.
