Hardware installation
4.4 Connecting the server to the mains
V
CAUTION!
The server is automatically set to a mains voltage in the range 100 - 127
V / 200 - 240 V. You may only operate the server if its rated voltage range
corresponds to the local mains voltage.
4.4.1 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 - 127 V / 200 - 240 V, 50/60 Hz, 28/14 A.The
minimum system configuration requires installation of at least two PSUs. The
PSU is considered hot-swappable(see
"Hot-plug power supply units" on
page 87 ). 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.
Installation requirements for AC redundant configurations
The AC redundant configuration is with two PSU plugged into a main AC source
and two other PSUs plugged into a separate AC source (e.g. UPS).
PSU Configuration Max. DC Loading DC Redundancy
1+1 (2 PSUs) 830W Yes
2+2 (4 PSUs) 1580W Yes
