4 – Installation Installing a Switch

D

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.As the switch powers up, the chassis LEDs mark the process with the following sequence:

a.All chassis LEDs illuminate briefly as the BIOS starts.

b.When the BIOS is complete, the Input Power LED remains illuminated while the other LEDs are extinguished.

c.After about a minute, all LEDs illuminate again when the switch Power-on Self Test (POST) completes. The POST tests the condition of firmware, memories, data-paths, and switch logic circuitry.

d.About 10 seconds later, the switch is operational: the Input Power LED remains illuminated, the Heartbeat LED flashes steadily, and the two remaining LEDs are extinguished. 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 indicates that an error has occurred. Refer to ”Heartbeat LED Blink Patterns” on page 5-1for more information about the error blink pattern.

4.Confirm that the Output Power LEDs on both power supplies are illuminated. If not, check the power cords and the AC voltage source. Refer to ”Output Power LED Is Extinguished” on page 5-11for more information about troubleshooting procedures.
