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 18 on page 35.
5.
Pull both the bracket and the cable (
2
) away from the SAN Volume Controller 2145-CG8 or
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:
1. With the node turned off, unscrew the retaining screw
1
, shown in Figure 19, half a turn, but do not
fully loosen or remove it.
2. Slide the bracket to the right just enough to disengage the screw.
3.
Squeeze the top and bottom of the bracket together slightly and turn the bracket at a slight angle to
remove both lips of the bracket from the node frame.
4. Slide the bracket back onto the power cable and then slide it off the cable.
5.
Remove the power cable.
