Replace Rear Fan Cable Assembly

You can replace the rear fan cable from a powered-off system.

The rear fan cable and front fan cable assemblies are field-replaceable units (FRUs). Only authorized Sun service providers should remove or install the I/O Chassis, front fan tray, rear fan cage, and the associated cable assemblies.

Preparing to Remove the Rear Fan Cable Assembly

Before you can remove the rear fan cable assembly, you must power off the system, remove all of the modules in the I/O Chassis, and then remove the empty I/O Chassis. You must also remove all of the rear fan modules, remove the empty rear fan cage, and remove the front fan tray to ease access to the cable. For more information, see Power Off System Before Service and the removal procedures in Replace I/O Chassis, Replace Rear Fan Cage, and Replace Front Fan Tray (Sun Blade 8000 Chassis).

Removing the Rear Fan Cable Assembly

  1. Remove the cable plate from the right side of the system chassis, as viewed from the rear of the chassis.

    The cable plate covers exposed cable to prevent damage. Use a Phillips screwdriver to remove the cable plate mounting screw, then slide the cable plate out of its mounting slots.

  2. Cut the cable ties holding the rear fan cable to the system chassis.

  3. Remove the rear fan cable connector.

    The rear fan cable connector is the lower black connector at the top left of the chassis, as viewed from the rear of the chassis. To release the connector, slide the connector down in its mounting slot, then push it out of the slot.

  4. Remove the rear fan cable assembly from the chassis.

Installing the New Rear Fan Cable Assembly

  1. Remove the new rear fan cable assembly from its packaging.

  2. Install the rear fan cable connector.

  3. Route the cable across the top of the chassis interior, down the right side of the chassis, and down through the cable plate opening at the right of the chassis.

  4. Use cable-ties to secure the cable to the chassis.

    Use cable-ties to attach the rear fan cable assembly to the square cable-tie mounting bases installed on the chassis.

    Note

    After the rear fan cable is routed down through the cable plate opening, you will see that there are three cable bundles of different lengths. The longest cable bundle should be routed to the left-most cable-tie mounting base, the shortest should be routed to the right-most cable-tie mounting base, and the other cable bundle should be routed to the middle cable-tie mounting base.

  5. Replace the cable plate that you previously removed.
