System backplane

Use this procedure to service a system backplane.

1. Power off the system and remove the power cords:

   Power off the system and remove the power cords: Before continuing ensure the device is not being used by the customer. If possible, shut down any running applications and the operating system before powering off the system. After the system is powered off, remove all power cords from all of the processor enclosures, starting with the primary processor enclosure (topmost) and then each secondary enclosure, working from top to bottom.

2. Remove the Front Cover

   Open the front rack door. Loosen the thumbscrew (A) on the right side of the cover. Slide the cover to the right and remove it from the system unit slot (B).

3. Disconnect the SMP Cable

   Carefully pull the handle (A) from the system until the connector is unseated. When the guide pins (B) are free, carefully pull the SMP processor cable away from the system unit. Repeat these steps for all SMP cable connectors that are present on the system you are servicing.

4. Remove the Control Panel or Control Panel Filler

   In the enclosure you are servicing, remove the control panel or, if present, the control panel filler, by pressing the locking tabs (A) on both sides of the panel, grasping the edges, and pulling it out of its bay (B).

5. Remove the Voltage Regulator Assemblies

   Squeeze the top of the latch (A) to release it, then rotate the latch out and then down. Grasp the pull ring (B) and slowly pull the voltage regulator out of the enclosure. NOTE: Pulling the voltage regulator assembly out of the card enclosure requires a large amount of force. The voltage regulator assembly is of substantial weight, so grasp it firmly when it is free of the card enclosure. Repeat these steps until all voltage regulator assemblies have been removed.

6. Remove the System Backplane Assembly

   Note: A shipping support clamp has been installed on your server. Removal is not required. This clamp will not interfere with the drawer front covers or machine operation. If removed, store for re-use when the server is relocated. Push the blue lever to the left and out from the system (A) to unlock the system backplane assembly. Pull the system backplane assembly out of the system using both hands. Attention: The system backplane assembly weighs 35 lbs and should not be pulled out using the blue lever. Grasp the backplane assembly firmly with both hands when it is free of the system.

7. Remove all Processor Assemblies or Fillers

   Pull the locking knobs out (A) to the unlocked position. Push the locking arms down and out (B) to unlock the system processor assembly. Lift the system processor assembly out of the system backplane assembly (C). Remove all system processor assemblies (or fillers) from the system backplane assembly. Record the location of each system processor assembly being removed.

8. Install all Processor Assemblies or Fillers

   Place the system processor assembly (A) into the new system backplane assembly using the location information that you recorded during the removal procedure. Lock the system processor assembly into place with the locking arms (B). Press the locking knobs (C) in to the locked position. Replace all system processor assemblies (or fillers) that were removed earlier.

9. Install the new system backplane assembly

   Align the system backplane assembly with the slot in the system. Slide the system backplane assembly into the system (A). Push the blue lever (B) to the right and in toward the system to lock the system backplane assembly.

10. Install the Voltage Regulator Assemblies

    Ensure that the voltage regulator assembly latch (A) is rotated out and down into the unlocked position. Carefully grasp the voltage regulator assembly and slide it into the enclosure. When the voltage regulator assembly is all the way into the card enclosure, rotate the latch (A) up into the locked position. Repeat these steps until all voltage regulator assemblies have been installed.

11. Install the Control Panel or Control Panel Filler

    In the enclosure you are servicing, carefully slide the control panel or, if present, the control panel filler, into the control panel bay (B) until you feel the locking tabs (A) lock in place.

12. Connect SMP Cable

    Align the guide pins (A) with the connectors (B) on the system unit. Using the handle (C), carefully push the SMP processor cable into the system unit connector. Repeat these steps for all SMP cable connectors that are present on the system you are servicing.

13. Install the Front Cover

    Position the cover on the front of the system unit so that the tab on the left side of the cover is in the matching slot (A) on the left side of the system unit. Tighten the thumbscrew (B) on the right side of the cover. Close the front rack door.

14. Install the power cords

    If you removed the power cords, reinstall the power cords for all of the processor enclosures. Install the cords in the following order: Secondary 2 Secondary 3 Primary Secondary 1
