Removing the drive backplane

Prerequisites

CAUTION:

To prevent damage to the drives and backplane, remove the drives from the system before removing

the backplane.

CAUTION:

Note the number of each drive and temporarily label them before you remove the drive so that you

can reinstall them in the same location.

NOTE:

The procedure to remove the backplane is similar for all backplane configurations.

1. Follow the safety guidelines listed in the

Safety instructions

2. Follow the procedure listed in the

Before working inside your system

Remove the backplane cover

Remove all drives

5. If required,

remove NVMe connector blank

6. If installed,

remove rear mounting front PERC module

7. Disconnect the drive backplane cables from the connector on the system board and backplane.

Steps

1. Press the blue release tabs to disengage the drive backplane from the hooks on the system.
2. Lift and pull the drive backplane out of the system.
