17 Maintenance
GO TO 
FIRST PAGE
The air filter life span depends on air quality and the cumulative airflow through the filter. Cleaner air and colder temperatures (lower 
flow rates) promote longer life span, which for preventive maintenance purposes is estimated to two to six years for a typical environ-
ment. Some markets and localized environments may be better or worse, for example the life span will be reduced if AMOD is located 
near a diesel generator exhaust or fast food restaurant exhaust. Visual inspection can wrongly lead to premature filter exchange and 
for this reason filter does not need to be replaced until an alarm is indicated. Remember that the AMOD air inlet path needs to be 
checked and maintained periodically depending on the characteristics of each individual site. 
For the detailed AMOD filter replacing procedure see the “Replacing System Module Units” document.

Appendix 1: Cable cleaning
Optical cable ends are susceptible to dirt during transportation, storage, or handling and as a result can stop functioning 
correctly. Dirty optical cable ends can have a big impact on the service quality of Nokia products and therefore it is very 
important to maintain them properly.
Nokia optical cable ends are always pre-cleaned and protected with dust caps to minimize any risks. It is highly recommended 
that optical cables be always cleaned prior to inserting and reinserting.
TIP: Keep optical cable end dust caps in place during installation and only remove those just prior to cleaning and connecting.
TIP: It is highly recommended that cable ends not contact anything else besides cleaning equipment before they are connected. 
For more information, see “Dry and wet cleaning” section.

 Preparation
 Fault detection
The condition of optical cables can be determined in many ways, including a visual inspection or by analyzing the cable loss. In 
order to complete fiber testing, it is required that condition of the cable be determined and the cable cleaned. The following 
tools can be used for this purpose.
Fiber scope
Used to inspect fiber cleanliness.
Light source and power meter
Used to measure the fiber 
insertion 
! WARNING! Risk of eye damage! 
Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and 
fiber-optic cables connected to transceivers emit laser light that can damage your eyes.
! Notice:
Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius 
can damage the cables and cause problems that are difficult to diagnose.
NOTE: 
If a cable does not work at the first try, inspect the cable using a light source and a power meter.

There are two cleaning methods: dry and wet cleaning. There are the following types of equipment for both types of cleaning:
NOTE: 
It is recommended that dry cleaning be used for regular cleaning. Wet cleaning should only be considered if multiple dry cleaning 
attempts failed to clear the issue.
! Notice:
After using any wet cleaning equipment, ferrule ends need to be re-cleaned immediately with dry cleaning equipment. 
NOTE: 
Do not wipe the cable in any other 
direction than the one indicated by the 
tool. Always use a fresh piece of tape. 
Do not use a dirty or used tape as this 
damages the optical cable.
NOTE: 
Never use the same stick, wipe, or surface 
area twice. Never apply more than one 
squirt of cleaning agent.

Inspect the cable to determine if there is dirt on the fiber end face or in-
creased insertion loss.
The acceptable insertion loss limits are:
for Multimode (MM): <1.5 dB, wavelength 850 nm
for Singlemode (SM): <1.0 dB, wavelengths 1310 nm and 1550 nm.
Is the insertion loss or dirt on fiber end face detected?
Clean the cable using one of the following methods:
a) When using a pen-style cleaner, fit the connector over the end of the 
optical cable, press down until the cleaner clicks and then remove the con-
nector.
b) When using a reel-based cartridge cleaning tool, take the end of the op-
tical cable and wipe the cable in the direction indicated on the tool.
Has the cleaning eliminated the cable loss?
Cable is clean and can 
be inserted.
Cable is clean and can be inserted. Have you already tried dry cleaning the cable five times?
Take the dirty cable and clean it using one of the following wet cleaning meth-
ods:
a) When using a cleaning stick, wet the tip of the stick with a cleaning agent and 
then apply to the optical cable by rotating the stick from six to eight times in 
the same direction.
b) When using wipes, apply one squirt of cleaning agent to the wipe, take the 
end of the cable and gently wipe the cable from wet to dry. Repeat dry cleaning 
immediately after wet cleaning to make sure no residue is left on the fiber end 
face.
Is insertion loss still present?
