## Remove a Storage Backplane

A storage backplane is a cold-service component that can be replaced only by authorized service personnel.

1. Power off the server.

   See Removing Power From the Server.

2. Remove all the hard drives from the front of the server for the storage backplane that you want to replace.

   You have to remove only hard drives 0–3 or drives 4–7, depending on which storage backplane you want to replace. Also, note the locations of the drives before removing them so that you can install them in their original slots afterwards. See Remove a Hard Drive.

3. Remove the main module from the server.

   See Remove the Main Module.

4. Take the necessary ESD precautions.

   See Prevent ESD Damage.
