Installing the rear backplane/cage kit
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 61.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another

addition to the instructions in this topic.
To install the rear backplane/cage kit, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. Prepare your server. See “Removing or extending the server from the rack cabinet” on page 63.
