Observing LEDs to Isolate the Problem

There are two LEDs on the left of the card:
  • Upper-left LED — Indicates power status. If it is not ON:
    • Verify that you have AC present to at least one power supply.
    • Verify that the CMC card is seated properly. You can release or pull the ejector handle, remove the CMC, reinstall the CMC making sure that the board is inserted all the way and the latch closes correctly.
  • Lower-left LED — This LED is multi-colored. When CMC is active and running, and there are no problems, the bottom LED is blue. If it is amber, a fault is detected. The fault may be caused by any of the following three events:
    • A core failure. In this case, the CMC board must be replaced.
    • A self-test failure. In this case, the CMC board must be replaced.
    • An image corruption. In this case, upload the CMC firmware image to recover the CMC.
    • NOTE: A normal CMC boot or reset takes over a minute to fully boot into its operating system and be available for login. The blue LED is enabled on the active CMC. In a redundant, two-CMC configuration, only the upper-right green LED is enabled on the standby CMC.
