Hot-swapping Power Supplies

If your server is configured with two power supplies, you can replace a failed or failing power
supply without powering down the server.
CAUTION
Because of chassis airflow disruption, a power supply bay should never be
vacant for more than two minutes when the server power is on. Exceeding
five-minutes might cause the system to exceed the maximum acceptable
temperature and possibly damage system components.
