About Card Status LEDs

LEDs indicate the status of a number of cards, as described in the following sections:

MIC Status

Each system has two management interface cards, each with nine LEDs: the Ready, Power, Redund, and Attention LEDs are on the left side of the card, and the Act1, Act 2, Link, and Remove LEDs are on the right side.

Status
Action

Four circles in a square pattern, representing light-emitting diodes: top 2 are on, bottom 2 are off.

Normal operation.
Card is acting as master.
No action required.

Four circles in a square pattern representing light emitting diodes: all off.

No power is applied.
Check that:
  • Power cables are connected securely.
  • MIC is seated properly.
  • MIC is not defective.

Hardware failure.
Check that the MIC:
  • Is seated properly.
  • Is in the proper slot: 5 or 6.
  • Has a valid image.
  • Is not defective.
