Exchange the microbay

This procedure guides you on how to remove and replace the microbay.

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.

Remove the microbay

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. At the rear of the rack, ensure that the SAS, power, and PCIe cables are properly labeled and then disconnect them from the microbay that is being removed. Leave the cables fastened to the cable tray behind the microbay. See Figure 1.
    1. Disconnect the four SAS cables from ports T1, T2, T3, and T4. Gently pull the release handle and then unplug each cable.
    2. Disconnect the power cable from port T6.
    3. Disconnect the PCIe cable from port T7. Gently pull the release handle and then unplug the cable.

  4. Remove the cable tray, with cables attached, from the rear of the microbay. See Figure 2.
    1. Loosen, but do not remove, the mounting screws Callout label 1 at the sides of the cable tray.
    2. Slide the cable tray to the left to clear the screws, then to the rear to remove.

  5. Remove the microbay from the microbay tray. See Figure 3.
    1. Press the release tabs Callout label 1 toward the center of the microbay.
    2. Slide the microbay back to the service position.
    3. Release the service latches Callout label 2 and Callout label 3 from the outside of the tray, then remove the microbay.

Install the microbay

Procedure

  1. If cable tray mounting screws are not present on the new microbay, transfer the screws from the old microbay to the new microbay.
  2. Move the T5 filler (if present) from the old microbay to the new microbay. See Figure 1.
  3. Slide the microbay into the microbay tray. See Figure 3.
    1. Release the service latches Callout label 2 and Callout label 3, as needed to insert the microbay.
    2. Ensure that the release tabs Callout label 1 latch into the microbay tray.
  4. Fasten the cable tray, with cables attached, to the rear of the microbay. See Figure 2.
    1. Slide the cable tray mounting slots onto the mounting screws Callout label 1 on the microbay.
    2. Tighten the mounting screws.
  5. Connect the SAS, power, and PCIe cables. Ensure that each cable is fully seated. See Figure 1.
    1. Connect the four SAS cables to ports T1, T2, T3, and T4. The latch releases are at the top of the connector.
    2. Connect the power cable to port T6.
    3. Connect the PCIe cable to port T7. The latch release is at the top of the connector.
  6. Exit this service information center parts exchange procedure and return to the procedure that sent you here.
