Replacing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D control-panel signal cable with the power off

Use this procedure to replace the control-panel signal cable on the server with the power off.

1. Perform the prerequisite tasks as described in Before you begin.
2. Stop the system. For instructions, see Stopping a system or logical partition.
3. Remove the front cover:
   • For a rack-mounted system, see Removing the front cover from a rack-mounted model.
   • For a stand-alone system, see Removing the front cover from a stand-alone model.
4. If your system is a rack-mounted system, place the system into the service position. For instructions, see Placing a rack-mounted model into the service position.
5. Remove the service access cover:
   • For a rack-mounted system, see Removing the service access cover on a rack-mounted system.
   • For a stand-alone system, see Removing the service access cover on a stand-alone system.
6. Disconnect the power source from the system by unplugging the system, as described in Disconnecting the power cords.
   Note: An optional power supply is available in the 8202-E4B, 8202-E4C, or 8202-E4D server. The 8205-E6B, 8205-E6C, or 8205-E6D server is equipped with a mandatory second power supply if two processor modules are installed. Before continuing with this procedure, ensure that all power to your system has been completely disconnected.

7. Attach the wrist strap.
   Attention:

   • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
   • When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
8. Remove the serial-attached SCSI (SAS) or Universal Serial Bus (USB) media device if one is installed. Press the release latch (A), unseat the media device (B), and remove the media cables (C) from the back of the device as shown in the following figures.
   Figure 1. Removal of a SAS media device

9. Remove the control panel. For instructions, see Removing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D control panel with the power off.
10. Connect the control-panel signal cable and its related USB cable. Ensure that all labels are facing up and that the USB cable is to the right of the signal cable.
    • For a rack-mounted system, follow these steps:
      1. Orient the signal cable so that its signal pad side is in contact with the corresponding connector pins of the planar.
      2. Route the signal cable and its related USB cable through the front of the system as shown in the following figure.
         Figure 3. Routing a signal cable in a rack-mounted system

         
      3. Connect the signal cable and its related USB cable to their ports on the back of the backplane as shown in the following figure. The connection points of the cables have labels that indicate where the cables plug in to the system backplane.

      4. Connect the other end of the signal cable to its port on the control panel. For instructions, see Replacing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D control panel with the power off.
    • For a stand-alone system, follow these steps:
      1. Remove the handle caps, cover screw, and side cover as described in Removing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D control-panel signal cable with the power off.
      2. Orient the signal cable so that its signal pad side is in contact with the corresponding connector pins of the planar.
      3. Fasten the control panel cable to its three clamped locations (A) as shown in the following figure.
      4. Slide the side cover (B) back into place and secure it with its cover screw (C) as shown in the following figure.
         Figure 5. Fastening a signal cable in a stand-alone system

         
      5. Reattach the rear (A) and front (B) handle caps by sliding them into place as shown in the following figure.

      7. Attach the other end of the signal cable to its port on the control panel when you reinstall the control panel. For instructions, see Replacing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D control panel with the power off.
11. Replace the control panel with the power off. For instructions, see Replacing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D control panel with the power off.
    Note: When installing a new signal cable, you can replace the control panel while the disk-drive backplane is still outside the system. After you have replaced the control panel, replace the disk-drive backplane as instructed in Disk drive backplanes.
12. Verify the installed part or repair:
    • If you replaced the part because of a service action, verify the installed part as described in Verifying the repair.
    • If you installed the part for any other reason, verify the installed part as described in Verifying the installed part.
