10 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. For this
reason, maintenance need not be performed according to a fixed schedule. Still you
should make checks from time to time. While doing so, you can look out for any dirt in
the vicinity of or inside equipment racks and remove it if required to insure that the air
supply and heat dissipation of the product are not affected.
The topical state of the hardware components can be monitored via a connected net-
work management client (NMC-511 FaultManager). For more information on the
NMC-511 FaultManager, please refer to the product documentation of the NMC-511
FaultManager.
10.1 Maintenance tasks
Contaminations may impair the air supply and heat output and possibly affect the oper-
ation. For this reason, the activities listed below should be performed in the interval
specified.
Early fan replacement
Independent of the ambient conditions at the installation site, the fan may have to be
replaced earlier. For this reason, please comply with the recommended visual inspec-
tions and intervals.
10.2 Periodical visual inspections
The table below lists the recommended tasks for maintaining the products. The visual
inspections should be performed in the intervals specified to be able to respond in due
time, e.g. in the case of changes at the location that may result in improper operation.
We recommend logging the results of the inspection.
