Notes on safety Important notes
V CAUTION!
● The device must only be connected to a properly grounded wall outlet
(the device is fitted with a tested and approved power cable).
● Make sure that the wall outlet of the building‘s wiring system is freely
accessible.
● Switching off the device does not cut off the supply of power. To do
this you must remove the power plugs.
● Before opening the unit, switch off the device and then pull out the
power plugs.
● Route the cables in such a way that they do not form a potential
hazard (make sure no-one can trip over them) and that they cannot
be damaged. When connecting up a device, refer to the relevant
notes in this manual.
● Never connect or disconnect data transmission lines during a storm
(lightning hazard).
● Systems which comprise a number of cabinets must use a separate
fused socket for each cabinet.
● The system unit and the directly connected external storage
subsystems should be connected to the same power supply
distributor. Otherwise you run the risk of losing data if, for example,
the central processing unit is still running but the storage subsystem
has failed during a power failure.
● Make sure that no objects (such as bracelets or paper clips) or liquids
fall into the device (risk of electric shock or short circuit).
● In emergencies (e.g. damage to housings, power cords or controls or
ingress of liquids or foreign bodies), immediately power down the
device, pull out the power plugs and notify your service department.
● Note that proper operation of the system (in accordance with IEC
60950/DIN EN 60950) is guaranteed only if slot covers are installed
on all vacant slots and/or dummies on all vacant bays and the
housing cover is fitted (cooling, fire protection, RFI suppression).
