ATTENTION!
● Make sure that the sockets on the device and the power points used are freely accessible.
● Switching off the devices does not disconnect them from the mains. To completely disconnect it
from the mains voltage, you must remove the power plugs from the power outlet.
● Before opening the device pull out the power plug first.
● Route the cables in such a way that they do not form a potential hazard (tripping) and cannot be
damaged. When connecting a device, refer to the relevant notes in the appropriate operating
manual.
● Do not connect or disconnect any data transmission cables during a thunderstorm (lightning
hazard).
● Systems which comprise a number of cabinets must use a separate fused socket for each cabinet.
● Always connect the server and the directly connected external storage subsystems to the same
power supply distributor. Otherwise you run the risk of losing data if, for example, the central unit is
still running but the storage subsystem has failed during a power cut.
● Make sure that no objects (such as bracelets or paper clips) fall into or liquids spill into the device
(risk of electric shock or short circuit).
● In emergencies (e.g. damaged casing, control elements or cable, penetration of liquids or foreign
bodies), unplug the device from the mains immediately, and contact your customer service center.
● Note that proper operation of the system (in accordance with IEC 60950-1/EN 60950-1) is only
guaranteed if slot covers are installed in all vacant slots and/or dummies in all vacant bays and the
housing cover is fitted (cooling, fire protection, RFI suppression).
