IBM SAN Volume Controller, Hardware Maintenance Manual

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:
v Optionally, turn off the node.
v
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” on page 20 refers.
2. Optional: Follow the procedure in MAP 5350 in the IBM System Storage SAN Volume Controller 2145
Troubleshooting Guide to verify that the node data is mirrored and synchronized, and that there are no
dependent volumes 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 22.
5. Pull both the bracket and the cable (

) away from the SAN Volume Controller 2145-CF8 power
supply.
6. Remove the cable-retention bracket from the power cord.
Removing the SAN Volume Controller 2145-8A4 cable retention bracket
The cable-retention bracket attaches to the back of the SAN Volume Controller 2145-8A4 node. It is
connected with one screw that already holds the rear plate of the power supply in place.
Remove the cable-retention bracket before you remove the SAN Volume Controller 2145-8A4 node from
the rack.
To remove the bracket from the node, perform the following steps:
