Look for a lit blue identify LED on the front or rear of the controller.
The front identify LED is behind the controller front bezel and might be difficult to see if
the bezel is installed.

Check the tags attached to the front of each controller for a matching part number.
2. Remove the controller front bezel, if one is installed, to access the front panel controls and
indicators.
3. Optional: Turn off the blue identify LED if you used it to locate the controller.

Replacing the services appliance
You might need to replace the appliance if it is not functioning optimally or if it has failed.
Before you begin
•
You have a replacement appliance with the same part number as the appliance you are
replacing.
•
You have labels to identify each cable that is connected to the appliance.
•
You have physically located the appliance that you are replacing in the data center.
Locating the controller in a data center
•
The appliance has been placed maintenance mode.

About this task
The StorageGRID node will not be accessible while you replace the appliance. If the appliance is
functioning sufficiently, you can perform a controlled shutdown at the start of this procedure.
Note: If you are replacing the appliance before installing StorageGRID software, you might not
be able to access the StorageGRID Appliance Installer immediately after completing this
procedure. While you can access the StorageGRID Appliance Installer from other hosts on the
same subnet as the appliance, you cannot access it from hosts on other subnets. This condition
should resolve itself within 15 minutes (when any ARP cache entries for the original appliance
time out), or you can clear the condition immediately by purging any old ARP cache entries
manually from the local router or gateway.
Steps
1. When the appliance has been placed maintenance mode, shut down the appliance.
