Replacing the high-speed SAS cable: 2145-CG8 or 2145-CF8

You can replace the high-speed SAS cable on a SAN Volume Controller 2145-CG8 or 2145-CF8 node.

About this task

Complete the following steps to replace the SAN Volume Controller 2145-CG8 or 2145-CF8 high-speed cable:

Procedure

  1. Remove the high-speed SAS adapter from the slot 2 riser-card connector at the rear of the system board, as described in Removing the high-speed SAS adapter assembly: 2145-CG8 or 2145-CF8.

    The high-speed SAS cable is shown in Figure 1.

    •  1  High-speed SAS cable plugged into the high-speed SAS adapter assembly
    •  2  High-speed SAS adapter assembly
  2. Attach the high-speed SAS cable to the high-speed SAS adapter.

    Attach the cable so that the end with the label is to the front of the node and the end without the label attaches to the adapter.

  3. Replace the high-speed SAS adapter , as described in Replacing the high-speed SAS adapter assembly: 2145-CG8 or 2145-CF8.
  4. Disconnect the boot-disk SAS cable from the disk controller and move it out of the blue bulkhead clip.
  5. Route the cable from the high-speed SAS adapter through the blue bulkhead clip behind the drive backplane.
  6. Attach the high-speed SAS cable to the SAS connector in the center of the back of the SAS drive back plane. Use the connector that connects to drive bays 0, 1, 2, and 3.

    The high-speed SAS cable is shown in Figure 2.

    •  1  Boot-disk SAS cable that is plugged into the disk-drive backplane to support drive bay 4
    •  2  High-speed SAS-adapter cable that is plugged into the middle of the backplane to support drive bays 0, 1, 2, and 3
  7. Reroute the boot-disk SAS cable through the blue bulkhead clip and reconnect the cable to the disk controller.

    The high-speed SAS cable is shown in Figure 3.
