DANGER
Do not open or service any power supply assembly. (D005a)
Replacing a SAN Volume Controller 2145-CF8 power supply
You can replace either of the two 675-watt hot-swap redundant power supplies in the SAN Volume
Controller 2145-CF8 node. 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 replace the
power supply.
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. This procedure assumes that you have turned off the node using MAP 5350, or that if
you did not turn off the node, you used MAP 5350 to ensure that the data is mirrored and synchronized,
and that there are no dependent virtual disks (VDisks). See MAP 5350 in the
IBM System Storage SAN
Volume Controller 2145 Troubleshooting Guide .
To replace the SAN Volume Controller 2145-CF8 power supply, perform the following steps:
1.
Read the safety information to which “Preparing to remove and replace parts” on page 20 refers.
2. Grasp the handle on the rear of the power supply, as shown in Figure 157 on page 148, and slide the
power supply forward fully into the node until it clicks in place. Verify that the power supply
connects firmly into the power-supply connector.
