Replacing the hot-swap-drive backplane

Attention: Do not open your server or attempt any repair before reading and understanding "Safety information"
on page iii and "Guidelines" on page 59.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• The hot-swap-drive backplane is sensitive to ESD. Ensure that you read and understand "Handling
static-sensitive devices" on page 60 first and carefully perform the operation.
• The following procedure is based on the scenario that you want to replace the backplane for up to eight
3.5-inch drives. The procedure is similar if your server is installed with the following types of backplanes:
– Backplane for up to sixteen 2.5-inch drives
– Backplane for up to eight 2.5-inch drives
To replace the 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 61.
3. Remove the server cover. See "Removing the server cover" on page 61.
4. Locate the backplane. See "Server components" on page 25.
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 131.
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.
