Replacing a power supply: 2145-CG8 or 2145-CF8

You can replace either of the two 675-watt hot-swap redundant power supplies in the SAN Volume Controller 2145-CG8 or 2145-CF8 node. These redundant power supplies operate in parallel, one continuing to power 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)
Multiple plugs: first set
 or
Multiple plugs: second set
 or
Multiple plugs: third set

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 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 volumes. See MAP 5350: Powering off a node.

To replace the SAN Volume Controller 2145-CG8 or 2145-CF8 power supply, complete the following steps.

Procedure

  1. Read the safety information to which Preparing to remove and replace parts refers.
  2. Grasp the handle on the rear of the power supply, as shown in Figure 1. 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.

    •  2  Power-supply release tab
    •  3  Power-supply handle
  3. Attach the cable-retention bracket to the power cord from the 2145 UPS-1U and connect the cord to the power-cord connector on the power supply, as described in Replacing the cable-retention brackets: 2145-CG8 or 2145-CF8.
  4. If necessary, turn on the node.
  5. To the left of the power-cord connector on each power supply, verify that the AC power LED (  1 ) and the DC power LED ( 2 ) are lit, as shown in Figure 2.

    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 ).
