You can remove and replace either of the two 675-watt hot-swap
redundant power supplies in the SAN Volume Controller 2145-CF8.
These redundant power supplies operate in parallel, one continuing
to power the node if the other fails.
DANGER
Multiple
power cords. The product might be equipped with multiple power cords.
To remove all hazardous voltages, disconnect all power
cords.
Ensure that you are aware of the procedures
for handling static-sensitive devices before you remove the power
supply.
This service action requires you to:
- Optionally, turn the node off.
- Disconnect the power cable on each power supply that you are removing.
Important: You can hot swap the
power supply. However, using MAP 5350 to power off the node through
proven methods avoids risking an abrupt power failure on the node,
which avoids the possible corruption of data.
To remove
the SAN Volume Controller 2145-CF8 power
supply, perform the following steps:
- Read the safety information to which Preparing to remove and replace parts refers.
- 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 the power supply,
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.
- 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.
- Optional: Wait for the node to
turn off completely if you are not hot-swapping the drive.
- Remove the cable-retention bracket and the
power cord from the power supply that you are replacing, as described
in Removing the SAN Volume Controller 2145-CF8 cable-retention brackets.
- To remove the power supply, press and hold the release
tab 2 to the left. Grasp the handle 3 on
the rear of the power supply, as shown in Figure 1, and pull the
power supply out of the node.

- If you are instructed to return the power supply, follow
all packaging instructions, and use any packaging materials for shipping
that are supplied to you.
