IMPORTANT: After a power failure, the system automatically returns to the On state when A/C

power is restored, except in the following cases:

• If both power supplies are damaged.

2. Verify that the power LED is green.

3. Verify that the power source is working:

remove and reinstall the power supplies to verify that they are seated properly.

b. Remove and inspect AC power cords from both power supplies and reconnect them.
