Initial POWER-UP

LBI-39128

INSTALLATION

Procedure

The following steps involve equipment in the Site Controller cabinet, except as noted:

1.Mark the cables and wires going to the old PMU as follows:

∙Mark “Antennas 1-4” on the cable going to the DB- 15 connector on the back of old PMU marked “Antennas 1-4”.

∙Mark “Transmitters 1-9” on the cable going to the DB-37 connector on the back of the old PMU marked “Transmitters 1-9”.

∙Mark “Transmitters 10-18” on the cable going to the DB-37 connector on the back of the old PMU marked “Transmitters 10-18”.

∙Mark “Transmitters 19-20” on the cable going to the DB-25 connector on the back of the old PMU marked “Transmitters 19-20”.

∙Mark “RS-232” on the cable going to the DB-25 connector on the back of the old PMU marked “RS-232”.

∙Mark “+” on the wire going to the screw terminal marked “+”.

∙Mark “–” on the wire going to the screw terminal marked “–”.

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

3.Disconnect the cables and wires from the old PMU.

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

∙Connect the five DB-25 connectors on the other end of the adapter cable marked “P5”, “P6”, “P7”, “P8”, and “P9” to Port 1 through Port 5 respectively on the back of the new PMU.

6.Connect the 188D6496P1 adapter cable as follows:

∙Connect the DB-15 connector on the adapter cable marked “P2” to the existing cable (disconnected from the old PMU) marked “Antennas 1-4”.

∙Connect the DB-25 connector on the adapter cable marked “P3” to Port 7 on the back of the new PMU.

7.Connect the existing cable (disconnected from the old PMU) marked “RS-232” to the right VDT Interface connector on the back of the new PMU.

8.Connect the existing wires (disconnected from the old PMU) marked “+” and “–” to the screw terminals on the back of the new PMU marked “+” and “–” respectively.

9.Double check the installation using the interconnection diagram shown in Figure 12.

5.Connect the 188D6451P1 adapter cable as follows:

∙Connect the two DB-37 connectors on the adapter cable marked “P2” and “P3” to the existing cables (disconnected from the old PMU) marked “Transmitters 1-9” and “Transmitters 10-18” respectively.

∙Connect the single DB-25 connector on one end of the adapter cable marked “P4” to the existing cable (disconnected from the old PMU) marked “Transmitters 19-20”.

10.Set the power switch on the back of the PMU to the “Off” position.

11.Turn on the main 12V power supply for the cabinet.

After the PMU equipment has been mounted and checked, you are ready for the initial power-up of the PMU.

1.Temporarily disconnect the data link cable to the Site Controller computer from the right-hand VDT Interface
