How to Remove a Power Supply Unit (PSU)

1.Identify the power supply by its position and designation or, if it has failed, by its steady on Service Action Required indicator. A power supply in a fault state has a lit amber-color Service Action Required indicator.

2.To unlock the power supply lever, squeeze together the two green release latches at the end of the lever. This action is accompanied by an click sound.

3.To disengage the power supply from its internal connector, rotate the lever to the left. The pawl at the hinged end of the lever engages the sidewall of the server and provides the pivot point for the leverage necessary to disengage the power supply. This action leaves the power supply extending partially from its slot.

Caution - Pinch point. When operating the lever, keep your fingers clear of the hinged end of the lever.

4.To remove the power supply, use two hands to slowly slide it completely out of the server.

5.Place the removed power supply on an anti-static mat.

How to Install a Power Supply Unit (PSU)

1.Ensure that the power supply lever is in its fully open position. To open the power supply lever, squeeze together the two green release latches at the end of the lever and rotate the lever to the left.

2.Align the power supply with its slot. Ensure that the connector end of the PSU is at the opening of the slot and that the open hinge on the front of the PSU is at the bottom and to the left.

3.Slide the power supply into the slot until it stops.

4.To install the power supply, rotate the lever to the right. The pawl at the hinged end of the lever engages the sidewall of the server and provides the pivot point for the leverage necessary to draw the power supply into the slot and engage the internal connector.

Caution - Pinch point. Keep your fingers clear of the backside of the lever.

5.Verify that the green Power OK indicator on the power supply indicator panel turns on steady and that the amber Service Action Required indicator is not lit. The Service Action Required indicator lights when the component is in a fault state.

How to verify the Power Supply is working properly

Login to the SP to Check Power Supply status.

-> show /SYS/PSx -l all

Note: The "x" represents the Power Supply number that was replaced

Sample:

-> show /SYS/PS0 -l all
