Note: The following procedure is based on the scenario that you want to replace the backplane for up to nine
3.5-inch drives. The procedure is similar if your server is installed with the following types of backplanes:
• Backplane for up to twelve 3.5-inch drives
• Backplane for up to nine 3.5-inch drives
• Backplane for up to sixteen 2.5-inch drives
• Backplane for up to eight 2.5-inch drives
To replace the front backplane, do the following:
1. Remove all external 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 69.
3. Remove the server cover. See "Removing the server cover" on page 69.
4. Locate the backplane. See "Server components" on page 29.
5. Remove all the installed drives and dummy trays (if any) from the drive bays. See "Installing or replacing
a hot-swap drive" on page 141.
6. Record the cable connections on the backplane and then disconnect all cables from the backplane.
7. Press the two latches in the direction as shown until the latches are disengaged from the chassis.
