Power supply units
The power supply unit (PSU) is an internal hardware component which supplies power to the components in the system.
Your system supports one of the following:
● Two 2000 W, 1600 W, 1100 W, or 750 W AC PSUs
● Two 1100 W DC PSUs
NOTE:
For more information, see
CAUTION:
If two PSUs are installed, both the PSUs must have the same type of label. For example, Extended
Power Performance (EPP) label. Mixing PSUs from previous generations of XC Series Appliance and XC Core
System is not supported, even if the PSUs have the same power rating. Mixing PSUs will result in mismatch
condition or failure to turn the system on.
NOTE:
Titanium PSU is nominally rated for 200 V AC to 240 V AC input only.
NOTE:
When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without
redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUs
when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs is put into the sleep mode when system utilization
is low in order to maximize efficiency.
NOTE:
If two PSUs are used, they must be of the same maximum output power.
Hot spare feature
Your system supports the hot spare feature that significantly reduces the power overhead associated with power supply unit
(PSU) redundancy.
