RPS Maintenance
In terms of required maintenance, you only need to verify the connections to the RPS from
each of the sector controllers. After verifying the connections, you should test each sector
controller in turn, to ensure that the RPS will cut in as required in the case of a failed power
supply.
Note
This work should be done in a maintenance window in case you encounter any
issues and a sector controller is powered down.
Step 1
Connect each sector controller to the RPS. Detailed instructions, for connecting each
sector controller to the RPS, are provided in the RedMAX Base Station Installation
Guidelines.
Step 2
Disconnect the first sector controller from it’s primary power source. The RPS scans the
devices and when a power outage is detected, sets and delivers the required power to the
device.
Step 3
Verify that the sector controller continues to operate as outlined in “Establishing and
Recording the Baseline Configuration” on page 2-15.
Step 4
Re-connect the primary power source for the sector controller and again verify that the
device continues to operate as outlined in “Establishing and Recording the Baseline
Configuration” on page 2-15.
Step 5
Repeat this for each sector controller that is connected to the RPS.
Step 6
Record all of your results and file the written report with your other maintenance logs.
Uplink Power Control
An important factor in overall network performance is the uplink power control of a
RedMAX AN100U/UX.
This feature allows the sector controller to automatically adjust the transmit power level for
all registered subscriber units in its sector. This is done by enabling, the SS TX Power
Control Enable option on the sector controller and specifying an associated Reference
RSS value.
When this option is enabled, the sector controller continually monitors the registered
subscriber units and adjusts their transmission power to maintain optimum levels
according to the preset reference RSS. This feature allows the overall system to achieve
a determined noise level for the uplink whenever the network is fully loaded.
The Reference RSS can be set between -40 and -95dBm. For optimum performance this
parameter should be carefully configured dependant on the following factors that are
initially determined during the design of the network and adjusted after installation, to
satisfy practical network requirements for each sector controller. The exact Reference
RSS value depends on the following factors:
