Hardware Installation and Maintenance Guide, Version 11.50.3

You prepare to replace a power canister in a 60-drive controller shelf or drive shelf by collecting support data about your storage array and locating the failed component.

From ThinkSystem System Manager, review the details in the Recovery Guru to confirm that there is an issue with the power canister and select Recheck from the Recovery Guru to ensure no other items must be addressed first.
Check that the amber Attention LED on the power canister is on, indicating that the canister has a fault. Contact technical support for assistance if both power canisters in the shelf have their amber Attention LEDs on.

This task describes how to prepare to replace a power canister for the following controller shelves:

DE4000H controller shelf (4U)
DE6000H controller shelf (4U)
DE600S drive shelf

You can replace a power canister while your storage array is powered on and performing host I/O operations, as long as the second power canister in the shelf has an Optimal status and the OK to remove field in the Details area of the Recovery Guru in ThinkSystem System Manager displays Yes.

While you perform this task, the other power canister supplies power to both fans to ensure that the equipment does not overheat.

Collect support data for your storage array using ThinkSystem System Manager.
1. Select Support > Support Center > Diagnostics.
2. Select Collect Support Data.
3. Click Collect.
The file is saved in the Downloads folder for your browser with the name support-data.7z.
From ThinkSystem System Manager, determine which power canister has failed.
1. Select Hardware.
2. Look at the power icon to the right of the Shelf drop-down lists to determine which shelf has the failed power canister.
  If a component has failed, this icon is red.
3. When you find the shelf with a red icon, select Show back of shelf.
4. Select either power canister or the red power icon.
5. On the Power Supplies tab, look at the statuses of the power canisters to determine which power canister must be replaced.
  A component with a Failed status must be replaced.
  Attention: If the second power canister in the shelf does not have Optimal status, do not attempt to hot-swap the failed power canister. Instead, contact technical support for assistance.
Note: You can also find information about the failed power canister in the Details area of the Recovery Guru, or you can review the information displayed for the shelf, or you can review the Event Log under Support and filter by Component Type.
From the back of the storage array, look at the Attention LEDs to locate the power canister you need to remove.
You must replace the power canister that has its Attention LED on.

Power LEDs. If it is Solid green, the power canister is functioning correctly. If it is Off, the power canister failed, the AC switch is turned off, the AC power cord is not properly installed, or the AC power cord input voltage is not within margin (there is a problem at the source end of the AC power cord).

Attention LED. If it is Solid amber, the power canister has a fault, or there is no input power to this power canister, but the other power canister is operating.

Go to Remove failed power supply.
