How to Install the Power Distribution Board

What to Do

1. Position the power distribution board in its mounting brackets on the chassis ceiling and floor.

   Align the two captive screws at the top and bottom edges of the board with the two holes in the mounting brackets. The four large power connectors along the edge of the board should face the power supply bays.

2. Tighten the two captive Phillips screws that secure the board to its mounting brackets.

   It helps to separate the board slightly from its mounting brackets in order to engage the screws in the screw holes.

3. Reconnect all cables that you previously detached from the power distribution board.

   Start at the top of the board and work your way down.

   1. Connect the keyswitch/LED cable at connector J0401.

   2. Connect the system interlock cable at connector J0501.

   3. Connect the two power sense cables at connectors J0201 and J0202.

   4. Connect the DC power cables at connectors J0204, J0205, and J0206.

   5. Connect the UltraSCSI power cable at connector J0207.
