You may need to reconfigure the server after installing some expansion cards. You may also need to install software that came with the card. Check the card documentation for additional information.

Power supplies

The server ships with as many as three 350-W hot-swap power supply modules. With all three modules, the server provides N+1 power supply redundancy, letting you hot-swap a power supply module if one fails. If the power distribution system fails you must replace the entire power supply.
