Maintenance
The system requires minimum maintenance.
To keep the system in good condition, do the following:
– Clean the units (section Clean the units, page 105)
– Clean the air inlets (section Clean air inlets, page 105)
– Check connectors and grounding (section Check the connectors and grounding, page
105).
Warning!
Dangerous mains voltages are present inside the units. Disconnect the main power supply
before you do any maintenance.
Clean the units
Periodically you must clean all units with a damp, lint-free cloth.
Clean air inlets
The 19‑inch units can collect dust as a result of the internal fans. Once a year you should use a
vacuum cleaner to clean the air inlets of all units in the 19‑inch racks.
Check the connectors and grounding
Periodically check:
– All cable connections.
– The ground (PE) connection of the system components.
