0110 - Failure Detected on One IMT bus

A fault has been detected on one IMT bus.

Example
RLGHNCXA21W 00-02-07 11:02:30 EST  EAGLE 35.0.0
*  0100.0110  * IMT SYSTEM          Failure detected on one IMT bus

Alarm Level: Minor

Recovery

  1. Visually check the IMT LEDS on the front of the cards.
    A red LED or LEDs denotes an IMT fault. If the top LED of the pair is red, there is a fault on IMT A. If the bottom LED is red, there is a fault on IMT B. See Figure 3-4.

  2. Note the card location or locations for cards with a red LED(s).
  3. Using the card location(s) noted in 2, connect the card back to the IMT with the command conn-imt.

    For example, enter:

    conn-imt : loc =x : bus = y

    where x is the card location stenciled on the shelf of the system and y is the IMT bus to be returned to service.

    The following message appears using card location 1106 and IMT bus A :
    RLGHNCXA03W 00-02-07 11:02:30 EST  EAGLE 35.0.0
        Connect IMT Bus A command issued to card 1106
  4. If the connection command is successful, the Card connected to IMT message appears.
    RLGHNCXA03W 00-02-07 11:02:30 EST  EAGLE 35.0.0
        0100.0006    IMT   BUS A         Card connected to IMT
  5. If the connection command is not successful and the fault does not clear, reseat the card

    warning:

    Resetting, reseating, or replacing a LIM will cause both links on the card to fail. If the card is a LIM, place the links on the LIM out of service by entering the dact-slk command.
  6. If the fault does not clear, replace the affected card.
  7. If the fault does not clear, replace the IPMX card servicing the affected card.

    warning:

    Replacing an IPMX card causes the IMT to go down. (IPMX in Slot 09 affects IMT A and IPMX in Slot 10 affects IMT B.) Do not perform this step if the other bus also has a fault. Contact My Oracle Support (MOS).
  8. If the fault has cleared and any of these cards are LIMs, place the links assigned to these cards back into service using the act-slk command.
  9. If these steps do not clear the fault, contact My Oracle Support (MOS).
    Refer to the Maintenance Manual for card removal/replacement procedures.
