Installing the Power Trays

1 Power enclosure
2 Three front captive screws
Step 2
Position and align the two rails on each side of the underside of the power enclosure with the two rails at the top of the
FCC. When the shelf is aligned properly, it will easily slide in place.
Step 3 Slowly push the power enclosure forward until the front flange with the three captive screws engages with the front of
the FCC.
Step 4 Loosely tighten the captive screws (two per side) on the power enclosure, and then loosely tighten the three captive
screws on the front flange.
Step 5
Repeat Step 4, tightening all captive screws to firmly attach the power enclosure to the FCC.
Step 6 Attach the two D-Sub connector cables to the two PCM connectors on back of the power enclosure and tighten the captive
screws on each cable connector. The individual PCMs are labeled PCM0 and PCM1.
Step 7
Tighten the captive screws on each cable connector.
