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.
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 5-1 for 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 5-11 for more information about
troubleshooting procedures.
Note: To provide redundancy in the event of an AC power circuit failure,
connect the switch power supplies to separate AC circuits.
