Replacing a power supply: 2145-SV1
You can replace either of the hot-swap redundant power supplies in the SAN Volume Controller 2145-SV1 node. These redundant power supplies operate in parallel; one continues to provide power to the node if the other fails.
Before you begin
DANGER
Multiple power cords. The product might be equipped with multiple
power cords. To remove all hazardous voltages, disconnect all power cords. (L003)
Ensure that you are aware of the procedures for handling static-sensitive devices before you replace the power supply.
About this task
Important: You can "hot swap" the power supply. However, using MAP 5350: Powering off a node to power off
the node avoids risking an abrupt power failure on the node, which avoids the possible corruption of
data. This procedure assumes that you turned off the node by using MAP 5350. 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 volumes. .
Complete the following steps to replace a power supply on a 2145-SV1 node.
Procedure
- Slide the power supply forward fully into the node until it clicks in place. Verify that the
power cord connects firmly into the power-supply connector. Figure 1. Replacing the 2145-SV1 power supply
- Verify that the AC power LED ( 1 ) and the DC power LED
( 2 ) are lit. Each power supply has a set of indicator LEDs, as shown in
Figure 2. In this example, the figure shows the LED
indicators for power supply 1. Figure 2. 2145-SV1 AC, DC, and power-error LEDs
