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: Powering off a SAN Volume Controller node.
To replace the SAN Volume Controller 2145-CF8 power supply, perform the following steps:
- Grasp the handle on the rear of the power supply, as shown
in Figure 1, 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.
- 1 Power supply
- 2 Power-supply release tab
- 3 Power-supply handle
- To the left of the power-cord connector on each power supply,
verify that the ac power LED, as shown by 1 in Figure 2, and the dc power
LED ( 2 ) are lit.
The green power LEDs indicate that the power supply is operating correctly. A power-supply error is indicated by the amber power-supply error LED ( 3 ).
