8.3.4.3 Maintaining the pumps
Check the pumps every three months for smooth running, leaks and normal housing
temperatures. If the pumps leak, then please contact
Technical Support (Page 139).
8.3.4.4 Maintaining the fans of the additional cooler
Perform a visual inspection every three months. During the visual inspection of the fans, check
for smooth running and normal housing temperatures.
The average service life of the fans is approximately 50,000 hours. However, the actual service
life depends on additional influencing quantities, for example, the ambient temperature and
cabinet degree of protection. As a consequence, the service life can deviate from this value
on a case-for-case basis.
Replace the fan in a timely manner in order to maintain the availability of the drive.

NOTICE
Cleaning fiber-optic cables and electronic components with a damp rag
Fiber-optic cables, fiber-optic cable bundles and electronic components can be damaged if
cleaned using a damp rag.
If the components are very dusty, remove the dust using a dry, lint-free cloth. In so doing, do
not bend the fiber-optic cables.
8.4.2 Cleaning frame components
Use
a dry, clean, lint-free ESD cleaning cloth. Wipe all external parts of the rack with it. Make
sure that the dirt is not distributed, but actually removed by constant changes of the wiping
surface of the cloth. For severe pollution, use a cleaning cloth soaked in ethyl alcohol, but not
to the extent that the alcohol drips.
