H/S LED

The blue H/S LED indicates whether the NIU is seated properly. Diagram showing the H/S LED

Possible states of the H/S LED include:

  • on/blinking — indicates that the NIU is not seated properly. When this occurs, ensure that you remove power to the platform and attempt to properly lock the NIU to the chassis. Then apply power to the chassis. If the H/S LED is no longer lit, proceed with normal operations.

  • off — when the PWR LED is on, this indicates that the NIU is seated properly in the chassis.
