Preventive maintenance
The Nokia InLite system requires a minimum of maintenance and supervision.
Should an alarm condition occur, its location can readily be determined, using the
laptop PC, then quickly corrected.
To ensure the continued integrity of the InLite system, certain maintenance tasks
must be performed at regular periods.
2.1
Periodic checks
Visual inspection and cleaning
Check that the following conditions are satisfied:
2.2
1.
The Main Unit (MU) is firmly secured in position.
2.
The MU is not damaged in any way and that the lock performs its function
correctly.
3.
The MU is clean and free from dirt. (Clean the surfaces as necessary.)
4.
The green LEDs on in all plug-units inside the MU (i.e., there are no alarm
conditions).
5.
Each Remote Unit (RU) is properly secured in its position.
6.
The installed RUs are not damaged.
7.
The red LED (Fault) indicator on the RU is not lit.
8.
The RU is clean and free from dust or dirt. (Clean the surfaces as
necessary.)
9.
Exposed cables (RF, optical and power) are not damaged or under stress.
Action plan
It is recommended that an action plan be prepared if a fault occurs in MU or RUs.
The purpose of this plan is to correct the fault and if necessary, replace any faulty
unit minimal traffic disruption.

M aint
enance
Consult with the indoor network planners and use the Switch Matrix capability to
reroute services and capacity to other MUs or RUs to reduce or avoid cut in
services or in RF coverage.
Pay attention to the fact that Intelligent Network dedicated services (e.g., GSM
Office, Private Virtual Network) located in a specific area of a building cannot be
relocated.
If it becomes necessary to replace BTS RF cables, contact the Operations and
Maintenance Centre (OMC), advising them of possible internal or external alarms
and asking them to take the related TRXs out of service before starting any repair
activities.

Localising an RU fault
Normally, an RU fault is located with the use of the InLite Supervisor software
application. However, an RU has two LEDs (green and red) that are visible
externally. The LEDs are illuminated when the RU is in a fault state and not
functioning.
An RU fault is identified using the Supervisor software.
