Replacing the E5700SG controller

You might need to replace the E5700SG controller if it is not functioning optimally or if it has failed.
Before you begin
• You have a replacement controller with the same part number as the controller you are replacing.
• You have downloaded the instructions for replacing a failed E5700 controller canister.
• You have labels to identify each cable that is connected to the controller.
About this task
The appliance Storage Node will not be accessible when you replace the controller. If the E5700SG
controller is functioning sufficiently, you can perform a controlled shutdown at the start of this
procedure.
Note: If you are replacing the controller before installing StorageGRID Webscale software, you
might not be able to access the StorageGRID Webscale Appliance Installer immediately after
completing this procedure. While you can access the StorageGRID Webscale 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 controller 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. If the E5700SG controller is functioning sufficiently to allow for a controlled shutdown, shut
down the E5700SG controller.
