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:
• 1600 W, 1100 W, 750 W AC power supply units (PSUs)
• Two 1100 W DC PSUs
NOTE
: For more information, see the Support Matrix.
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.
