Removing the SAN Volume Controller 2145-CF8 cable-retention brackets

You can remove the two SAN Volume Controller 2145-CF8 cable-retention brackets when removing the power cords from the node.

The SAN Volume Controller 2145-CF8 uses two toolless cable-retention brackets, one to retain each cable from the uninterruptible power-supply to one of the two SAN Volume Controller 2145-CF8 power supplies, as shown in Figure 1.

Figure 1. SAN Volume Controller 2145-CF8 cable-retention brackets

Each cable-retention bracket attaches to the back of the SAN Volume Controller 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:

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 SAN Volume Controller node to verify that the node data is mirrored and synchronized, and that there are no dependent virtual disks (VDisks) before turning 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 VDisks on the node. With the partner node available and no dependent VDisks 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 completely 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-CF8 power supply.
6. Remove the cable-retention bracket from the power cord.
