Indoor Equipment Maintenance
For maintenance purposes it is easier to divide maintenance work between indoor and
outdoor maintenance. In some case the personnel required to perform maintenance of the
indoor equipment will be different than those required for the outdoor work.
Routine maintenance of the indoor equipment will be covered, in this chapter.
Performing a Visual Inspection of the IDU
Visually inspect data connections, power cables and grounding connections for indoor
equipment on a monthly basis. Ensure all connections are secure and look for any signs
of rust or other types of corrosion.
Step 1
Inspect all connections on the AN100U/UX IDU. All connections must be secure and
cables in good repair. Cables and connectors should be clearly labelled to facilitate
troubleshooting.
Step 2
Inspect all connections to the RPS, if installed. The RPS must be powered down before
disconnecting or re-connecting any devices.
Note
The AN100UX redundant power supply is a DC-type supply. The RPS power
must be connected using positive polarity, i.e. the +48 VDC RPS output
must be connected to positive input on the AN100UX. Refer to the RedMAX
Base Station Installation Guidelines for detailed instructions.
Step 3
Inspect all connections for local synchronization, if configured. Refer to the RedMAX Base
Station Installation Guidelines for details.
Step 4
Inspect all connections to the GPS, if installed. Refer to the Redline GPS Clock User
Manual and to the RedMAX Base Station Installation Guidelines for details.
Step 5
Inspect all connections to the computer, syslog server and any other computers that are
components of your OSS. Refer to the RedMAX Base Station Installation Guidelines for
details.
Step 6
Ensure all cables are secured and do not pose a tripping hazard.
Step 7
Ensure cables are not pinched or bound too tightly.
