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

You can remove and 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 remove the power supply.

About this task

This service action requires you to complete the following actions:
  • 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-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. Optional: Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power 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 volumes on the node. With the partner node available and no dependent volumes on the node, you do not lose access to data if this node accidentally powers off.
  3. 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.
  4. Remove the cable-retention bracket and the power cord from the power supply that you are replacing, as described in Removing the cable-retention brackets: 2145-CG8 or 2145-CF8.
  5. To remove the power supply  1 , 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.
