Removing and installing a hot-swap power supply

This procedure is used when either installing an optional hot-swap power supply or replacing a defective
power supply. The removal procedure is used only when replacing a power supply.
This procedure applies only to server models that have hot-swap power supplies. When you remove or
install a hot-swap power supply, observe the following precautions.
• The server comes with one 675-watt hot-swap 12-volt output power supply. The input voltage is 110 V
ac or 220 V ac auto-sensing.
• You can install an optional 675-watt hot-swap 12-volt output power supply for redundancy.
• These power supplies are designed for parallel operation. In the event of a power-supply failure, the
redundant power supply continues to power the system. The server supports a maximum of two
power supplies.
