Hot Swapping a Power Supply
If your server is configured with four power supplies, you can replace a failed or failing power supply without
powering down the server. Use the LEDs at the front of the power supply to determine the power supply status.
Each power supply module has three status LEDs above the input connector. If the center LED is lit, the power
supply needs to be replaced.
LED LED Name Symbol Color/LED State Description
A DC Power

Caution Because of chassis airflow disruption, a power supply bay should never be vacant for more than
three 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.
