• The server comes with one hot-swap 12-volt output power supply that connects to power supply bay 1.
The input voltage is 100-127 V ac or 200-240 V ac auto-sensing.
• Power supplies in the server must be with the same power rating or wattage to ensure that the server will
operate correctly. For example, you cannot mix 550-watt and 750-watt power supplies in the server.
• Power supply 1 is the default/primary power supply. If power supply 1 fails, you must replace the power
supply with the same wattage immediately.
• You can order an optional 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.
