B. Upgrade from Old PMU

Use this procedure only if your Site Controller cabinet has EDACS Interface panels and an old PMU.

This procedure consists of upgrading the Site Controller by replacing the old PMU, replacing the old Power Sensor interface module, and replacing the cables between them.

Parts Required

Before you start this procedure, be sure you have all the parts on hand. The parts for this procedure are shown in Table 3.

Procedure

The following steps involve equipment in the Site Controller cabinet only:

1.Turn off the main 12V power supply for the cabinet.

2.Mark “+” on the wire going to the screw terminal marked “+” on the back of the old PMU. Then disconnect this wire at the PMU end.

3.Mark “–” on the wire going to the screw terminal marked “–” on the back of the old PMU. Then disconnect this wire at the PMU end.

4.Mark “RS-232” on the cable going to the DB-25 connector marked “RS-232” on the back of the old PMU. Then disconnect this cable at the PMU end.

5.Disconnect any cables going to the connectors marked “Antennas 1-4”, “Transmitters 1-9”, “Transmitters 10- 18”, and “Transmitters 19-20” on the back of the old PMU. (There is no need to label these cables since they will not be used with the new PMU.)

6.Replace the old PMU with the new PMU. There will be a half rack unit space (7/8 inch) both above and below the new PMU.

7.Connect the existing wire labeled “+” in step 2 to the terminal labeled “+” on the back of the new PMU.

8.Connect the existing wire labeled “–” in step 3 to the terminal labeled “–” on the back of the new PMU.

9.Connect the existing cable labeled “RS232” in step 4 to the right-hand VDT interface on the back of the new PMU (see Figure 7).

10.Find the Power Sensor interface module mounted in the left end of the upper EDACS Interface Panel in the upper rear of the cabinet. If a cable is connected to the
