BX400 S1 Operating Manual 51
Installing the hardware
4.5.1 Cable routing
The cables are routed along the support uprights of the rack.
4.6 Connecting the system unit to the mains
The system unit has four bays for hot-swap power supply units. In the base
configuration, it is fitted with one power supply unit.
V CAUTION!
● Read the information on determining how many power supply units
are required (see "Hot-plug power supply units" on page 119).
● The power supply units automatically adjust to a mains voltage
between 100 - 240 V. The system unit may only be used if the local
mains voltage is within the voltage range of the system.
● The 1600 W power supply units may only be connected to 16 A
power outlets, a UPS, a 32 A power distribution unit, or CEE sockets.
When ordering the system unit, you must specify which socket type
is available at the installation location, so that the cables with the
appropriate C19 connectors can be supplied.
– For the Japanese market:
The 1600W power supply units may only be connected to NEMA
L6-15, IEC 60320-C20, or NEMA 5-15 sockets.
● Always connect the cable first to the power supply unit and then to the
mains.
Ê First connect the insulated C19 connector of the power cable to the power
supply units of the system unit, and then plug the connector into the UPS,
power distribution unit or an external socket. The system can be configured
to support *True AC redundancy or non-AC redundancy.
I True AC redundancy is recommended for systems used for critical
business applications. This will result in the system to continue operation
during a power failure as the redundant part of the subsystem is plugged
into a separate AC source [e.g. uninterruptable power supply (UPS)).
I Refer to tables below for maximum DC loading for both AC redundant
and AC non redundant configurations.
