• To implement n+n redundancy, there must be two external power sources and two PSUs attached to
• There must be an earth ground connection to the chassis that you are installing the replacement module.
Step 1 Holding the power supply unit with one hand underneath it 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. Carefully slide the power supply unit all the way into the slot until it clicks
into place.
Note If the power supply unit does not fit into the slot opening, turn the unit over and try
again.
Step 2 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 and tighten the locking screw.
Step 3 Attach the power cable to the electrical outlet on the front of the power supply.
Step 4 Make sure that the other end of the power cable is attached to the appropriate power source for the power supply. If the
power source has a switch, move it to "on".
Note 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.
Step 5
Verify that the power supply is operational by making sure that the power supply LED is green. For information on what
the power supply LEDs indicate, see the
