Installing a Switch

To energize the switch, do the following:

1.Connect the power cords to the AC power receptacles on the front of the switch chassis.

2.Connect each power cord to a 3-wire, grounded, AC outlet that delivers power in accordance with the power requirements in

Appendix A Specifications.

Note: To provide redundancy in the event of an AC power circuit failure, connect the switch power supplies to separate AC circuits.

3.Place one or both power On/Off switches in the On position to energize the switch logic circuitry. Confirm that the Input Power LED on the switch chassis is illuminated indicating that the switch logic circuitry is receiving DC voltage. If not, contact your authorized maintenance provider.

4.Confirm that the Output Power LEDs on both power supplies are illuminated. If not, do the following:

a.Check voltage at the AC power source.

b.Inspect the power cord.

c.Replace the power supply.

5.Observe the Heartbeat LED to determine the results of the Power On Self Test (POST). The POST tests the condition of firmware, memories, data-paths, and switch logic circuitry and passes a blink code to the Heartbeat LED. If the Heartbeat LED blinks steadily about once per second, the POST was successful, and you can continue with the installation process. Any other blink pattern appears indicates that an error has occurred. Refer to ”Heartbeat LED Blink Patterns” on page 5-2for more information about the error blink pattern.
