MAP2010 RPC card causes false fence

The failing RPC card has an internal problem that is causing it to fence the working RPC card when it should not.

About this task

The false fence must be reset before the failing RPC card can be replaced. The RPC-to-RPC communication cable is unplugged so the working RPC card does not continue to be fenced by the failing RPC card.

MAP2010 Section-1

Procedure

  1. Select the appropriate rack model:
  2. Verify that one of the two cards is fenced. Observe the green operational LED Callout label 1 on each RPC card. See Figure 1. Is the green LED indicator off on one of the cards?
    • Yes, continue at the next step.
    • No, neither RPC is fenced. The original failing condition is no longer present. Contact your next level of support before you cancel this problem.
  3. Unplug the RPC to RPC communication cable from the J208 connector on the failing RPC card (green LED is lit).
  4. Observe the green LED on the working RPC card (green LED was off). Is the green LED indicator lit?
    • Yes, continue at the next step.
    • No, the working RPC card did not unfence when the RPC-to-RPC communication cable that carried the fence signal was unplugged. Both RPC cards might be failing. Contact your next level of support.
  5. Return to the SAEL problem screen and continue.
    Note: Both RPC cards are not available and normal guided FRU replace procedures are used.

Procedure

  1. Place the management enclosure (Figure 2) in the service position and remove the top cover to gain access to the RPC card LED indicators.
    1. At the front of the rack, loosen the two screws and slide the Management enclosure out to the service position.
    2. At the rear of the cover, loosen the two thumbscrews and slide the cover back until it can be lifted and off.

  2. Verify that one of the two RPC cards is fenced (green LED indicator is not lit). Observe the green LED indicator on each RPC card. (Figure 3).

    Is the green LED indicator not lit on one of the RPC cards?

    • Yes, an RPC card is fenced, continue at the next step.
    • No, neither RPC is fenced. The original failing condition is no longer present. Contact your next level of support before you cancel this problem.

  3. Unplug the RPC to RPC communication cable from the J1connector on the failing RPC card (green LED indicator is lit).
  4. Observe the green LED on the RPC card that had the green LED not lit. Did that green LED indicator change to lit?
    • Yes, continue at the next step.
    • No, the working RPC card did not unfence when the RPC-to-RPC communication cable that carried the fence signal was unplugged. Both RPC cards might be failing. Contact your next level of support.
  5. Return to the SAEL problem screen and continue.
    1. Both RPC cards are now available and normal guided FRU replacement procedures are used.
    2. Replace the RPC card that had the green LED indicator lit from the start of this procedure.
