5.4 Connecting the server to the mains
V
CAUTION!
The server is automatically set to a mains voltage in the range
100 - 240 V or 200 – 240 V (depending on PSU model used). You may
only operate the server if its rated voltage range corresponds to the local
mains voltage.
5.4.1 Installation requirements
The power subsystem consists of:
– Power supply modules (PSU)
– A power distribution board (PDB)
The power supply subsystem can support up to 4 PSUs which all connect to the
PDB. The total system is rated 100 - 240 V, 24 - 16 A, 50 - 60 Hz or 200 – 240 V,
20 A (depending on PSU model used, refer to your system’s rating plate).The
minimum system configuration requires installation of at least two PSUs. The
PSU is considered hot-swappable. 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.
