About this task

The SAN Volume Controller 2145-CG8 or 2145-CF8 uses two toolless cable-retention brackets. One cable retention bracket routes a cable to the uninterruptible power-supply. Another bracket routes a cable to one of the two SAN Volume Controller 2145-CG8 or 2145-CF8 power supplies, as shown in the following figure.

Each cable-retention bracket attaches to the back of the SAN Volume Controller 2145-CG8 or 2145-CF8 node. The brackets connect without screws.

This service action requires you to:
  • Optionally, turn off the node.
  • Disconnect the power cable that the retention bracket is on.

To remove a cable-retention bracket, perform these steps:

Procedure

  1. Read the safety information to which Preparing to remove and replace parts refers.
  2. Optional: Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power off the node.
    Important: If you decide to hot swap a power supply, and that is why you are removing the cable retention bracket, use MAP 5350 to make all of the necessary checks that ensure that the partner node in the I/O group can take over all I/O group operations, if necessary, and that there are no dependent volume disks on the node. With the partner node available and no dependent volume disks on the node, you do not lose access to data if this node accidentally powers off.
  3. Pull back the cable-management arm if you are working from the rear of the rack, or slide the node out of the rack to the fully extended rail position if you are working from the front.
  4. When the node is turned off, from under the cable, carefully push the spring clip away from the cable to free the cable-retention bracket from the handle on the power supply.

    The spring clip is shown by  1  in Figure 1.

  5. Pull both the bracket and the cable ( 2 ) away from the SAN Volume Controller 2145-CG8 or 2145-CF8 power supply.
    Note: When you replace the power cords on the node, remember to replace the cable retention brackets.
  6. Remove the cable-retention bracket from the power cord.
