7 Maintenance
To ensure the proper operation of products, maintenance tasks and periodical visual
inspections are required.
The products have been designed for permanent and unsupervised operation. Neverthe-
less you have to perform checks every now and then. When doing so, you can detect and
remove dirt in the vicinity of or within equipment racks, so the air supply and heat dissipa-
tion of the products is always ensured.
Possible restrictions
Depending on the maintenance tasks and redundancy options, not all functions and fea-
tures may be available for the duration of the maintenance tasks.
The current state of the hardware components can be monitored via an NMC-511 Fault-
Manager. For additional information about the NMC-511 FaultManager, refer to the corre-
sponding product documentation.
7.1 Maintenance tasks
The required activities for maintaining the product are listed below. The maintenance
tasks must be performed in the intervals specified to ensure the proper operation of the
product. Contaminations can, for example, impede the air supply and heat dissipation
and negatively impact operation.
Maintenance tasks
Task/s Interval/s
Replacing the fan after 30 000 operating hours
Replacing the air filter mat depends on the environmental conditions
Replacing the BSCU battery every 10 years
Early fan replacement
Dependent on the environmental conditions at the installation site, the fan may have to
be replaced earlier. For this reason, please comply with the following recommended
visual inspections and intervals.
