Connecting power cords and verifying that the system attention LEDs
are green
Before powering on the system, you must connect the power cords to the power source and verify that
each component's attention light is green and flashing.
Do the following to connect power cords:
1. Plug the PDU power cords into the alternating current (AC) power source.
2. Wait at least 10 minutes for the system to complete its power application process.
3. Ensure that the system attention LEDs are green and flashing for each component.
