4.2.1. Step 1: Prepare to replace power supply
Prepare to replace a power supply in a 24-drive controller shelf or drive shelf.
Steps
1.
Collect support data for your storage array using ThinkSystem System Manager.
If a problem occurs during this procedure, you can use the saved file to troubleshoot the issue.
The system will save inventory, status, and performance data about your storage array in a
single file.
a.
Select Support › Support Center › Diagnostics.
b.
Select Collect Support Data.
c.
Click Collect.
The file is saved in the Downloads folder for your browser with the name, support-data.7z.
2.
From ThinkSystem System Manager, determine which power supply has failed. You can find
this information in the Details area of the Recovery Guru, or you can review the information
displayed for the shelf.
a.
Select Hardware.
b.
Look at the power
and fan icons to the right of the Shelf drop-down lists to
determine which shelf has the failed power supply.
If a component has failed, either or both icons are red.
c.
When you find the shelf with a red icon, select Show back of shelf.
d.
Select either power supply.
e.
On the Power Supplies and Fans tabs, look at the statuses of the power-fan canisters, the
power supplies, and the fans to determine which power supply must be replaced.
A component with a Failed status must be replaced.
If the second power supply canister in the shelf does not have Optimal
status, do not attempt to hot-swap the failed power supply. Instead,
contact technical support for assistance.
3.
From the back of the storage array, look at the Attention LEDs to locate the power supply you
need to remove.
You must replace the power supply that has its Attention LED on.
