Exchange the rack identity card

Before you begin

Icon for electrostatic discharge wrist strapUse approved ESD procedures to prevent damage.

Attention:
  • This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
  • If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
  • If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.
Notes:
  • All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
  • If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Determine rack version

Procedure

Determine the rack version.
  1. At the rear of Rack-1, observe the location of the Rack identity and Local remote switch cards. See Figure 1.
  2. Version 1, the cards are vertical and mounted to the left sidewall, go to Section-1 Rack Version 1.
  3. Version 2, the cards are horizontal and mounted to the top of the rack, go to Section-2 Rack Version 2.

Section-1 Rack Version 1

Remove the rack identity card (rack version 1)

Procedure

  1. To locate this FRU, take one of the following actions and then return here and continue to replace the FRU:
    • If this FRU has a FRU identify indicator, use the FRU identify indicator, which is listed in MAP1240 Locating FRUs by using identify indicators. If not, use the location code.
      Note: There might be cases where the FRU failure or fencing conditions prevent the FRU LED indicator from being lit even if the FRU has power.
    • Use the location code, which is listed in MAP1245 Finding FRUs by using location codes.
    • If there is no FRU identify indicator or location code, you were sent here by an isolation MAP or symbolic FRU procedure. Use the information in that procedure and the figures in this procedure to locate the proper part to exchange.
  2. Most, but not all, FRUs have identify indicators. Use the flashing amber or solid blue FRU identify indicators to ensure that you are working on the correct enclosure or FRU.
  3. Is the rack identity card being replaced in Rack 1?
    • Yes, go to step 4.
    • No, the rack identity card is being replaced in an expansion rack. Go to step 5.
  4. Remove the rack identity cables from both RPC cards, U2nnn.mmm.sssssss-C1-J1 and U2nnn.mmm.sssssss-C2-J1. See Figure 2. After the cables have been removed, go to step 6.
    Note: This end of the rack identity card cable is disconnected first to ensure that no unexpected signals reach the RPC card when the cable is disconnected from the rack identity card.
    Figure 2. Location codes for the RPC cards (Model 961)
    Location codes for the RPC cards (Model 961)
  5. Remove the rack identity cables from both DC-UPSs, U2nnn.mmm.sssssss-E1-J8 and U2nnn.mmm.sssssss-E2-J8. See Figure 3.
    Note: This end of the rack identity card cable is disconnected first to ensure that no unexpected signals reach the DC-UPS when the cable is disconnected from the rack identity card.
    Figure 3. Location codes for the DC-UPS (Models 961, 96E) (rear)

    Local/Remote switch
  7. Remove the screws fastening the rack identity card to the rack and then remove the card from the rack.

Install the rack identity card (rack version 1)

Procedure

  1. Install the rack identity card in the rack.
  2. Secure the rack identity card in place by reattaching the screws Callout label 1.
  3. Do not press the rack identity card white rocker switch at any time.
  4. The FRU verification tests for this FRU cannot detect disconnected or cross-connected cables. Use the location code label on each cable to ensure it is properly connected.
  5. Reconnect all cables at the rack identity card. See Figure 4.
    1. Reconnect the cables to J1 and J2.
    2. Reconnect the rack operator panel cable to J3.
  6. If you replaced the rack identity card in Rack 1:
    1. Reconnect the rack identity cable to RPC card connector C1-J1. See Figure 2.
    2. Reconnect the rack identity cable to RPC card connector C2-J1. See Figure 2.
    3. Go to step 8.
  7. If you replaced the rack identity card in an expansion rack:
    1. Reconnect the rack identity cable to DC-UPS, E1-J8. See Figure 3.
    2. Reconnect the rack identity cable to DC-UPS, E2-J8. See Figure 3.
    3. Go to step 8.
  8. Observe the rack identity card identify LED Callout label 1. See Figure 5.

    Is the LED blinking?

    • Yes, go to step 9.
    • No. The signal to blink the ID LED comes from both RPC cards. Ensure you properly connected the cables in step 6 and step 7. If they are properly connected, call the next level of support or replace the rack identity card again.

  9. Observe the rack identify LED Callout label 3. See Figure 6.

    Is the LED blinking?

    • Yes, go to step 10.
    • No. The signal to blink the rack identify LED comes from the rack identity card. Ensure the J3 cable is properly connected. At the front of the rack, open the cover and ensure the cable is properly connected to the LED assembly. If no problems are found, call the next level of support.
