The devices in the racks are supplied with power over power distribution units (PDUs).
SE /390
By default a basic rack contains four PDUs, each with 11 usable C13 outlets.
Each PDU is connected to the in-house power grid with CEE connectors 16A blue. For redundancy reasons, two phases are required. Two of the four CEE connectors are connected to each phase.
SE x86
The power distribution units to be installed in the SE x86 basic rack and in the extension racks can be selected. The following three types of PDU can be installed:
PDU with 11 usable C13 outlets, CEE connector 16A blue
3-phase PDU with 3 x 8 x C13 outlets, CEE connector 16A red
PDU with 8 x C13 outlets, CEE connector 32A blue
Connection of the power cables
Most of the hardware components in the SE server rack do not incorporate any switches which disconnect them from the power source. Consequently the power cables of the hardware components must be attached or detached when it is necessary to connect or disconnect the components from the power source.

CAUTION!
Equipment damage
All work on the power supply must be conducted by Customer Support.
Connect each power cable to a grounded service outlet located within the operator's reach.
The power cables must be connected in such a manner that the power consumption of the rack components does not exceed the maximum rated current of the circuit’s fuse and the maximum permissible current of the fuses in the power distribution unit in the rack.
Free sockets in the power distribution unit may not be used to connect other devices. The total permissible current for a power distribution unit could be exceeded if other devices were connected.
If you have additional requirements, please contact Customer Support.
