Installing a DC Power Supply

1. Remove the PSU from the electro-static bag.

2. Use the grab handle to slide the PSU into the switch PSU slot (install the PSU-exposed PCB edge connector first). The PSU slot is

keyed so that the PSU can be fully inserted in only one way. When you correctly install the PSU, it snaps into place and is flush with

the back of the switch.

3. Strip the insulation from the ends of the DC power wires, exposing approximately 13 mm (0.5 inch) of copper wire.

NOTE:

Reversing polarity when connecting DC power wires can permanently damage the power supply or the

system.

4. Insert the copper ends into the mating connectors and tighten the captive screws at the top of the mating connector using a #2

Phillips screwdriver.

NOTE:

To protect the power supply from electrostatic discharge, you must cover the captive screws with the rubber

cap before inserting the mating connector into the power supply.

5. Rotate the rubber cap clockwise to fix it over the captive screws.

6. Insert the mating connector into the power supply.
