Amosphere NPM Installation Procedures (WCS)

Check PDP Sector Configuration

The PDP sector configuration switch, located inside the PDP, configures the

circuit breakers to support a specific number of radio sectors (1–6). In an NPM

supporting fewer than six sectors, some of the circuit breakers are not used and

are therefore left in the OFF (down) position. The OAMP software uses the

switch to determine if a circuit breaker has tripped or is not used.

The switch is set at the factory and does not normally need to be adjusted.



To check the PDP sector configuration

1 Consult your E1 package to determine the number of sectors your NPM is

intended to support.

2 If necessary, remove the PDP rear cover. The rear cover attaches to the PDP

using four #1 Phillips screws.

3 Ensure that the PDP sector switch is set to the number of sectors that your NPM is

intended to support.

If the switch is not set correctly, set the switch to the correct value:

i Turn screw counter-clockwise as far as possible to find sector 1 position.

ii Turn screw clockwise so that slot points to correct number of sectors.

Figure 4.3 shows the location of the PDP sector switch.
