8 Maintenance
To ensure the correct operation of the product, maintenance procedures and periodical
visual inspections are necessary.
The products have been designed for permanent, unsupervised operation. For this rea-
son, maintenance need not be performed according to a fixed schedule. Still, you
should perform inspections from time to time, e.g. of the installation site. In this case,
you can look out for any soiling in the vicinity of or inside the equipment rack and
remove it, if required, so as to prevent an impairment of the air supply and heat conduc-
tion of products.
The topical state of the network components can be monitored via a connected network
management client (NMC-511 FaultManager). For more information on the NMC-511
FaultManager, please refer to the product documentation of the NMC-511 FaultMan-
ager.

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.
