Replacing the hot-swap hard-disk-drive backplane
Attention: Do not open your storage product or attempt any repair before reading and understanding “Safety
information” on page iii and “Guidelines” on page 41.
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 hard-disk-drive backplane is sensitive to ESD. Ensure that you read and understand
“Handling static-sensitive devices” on page 42 first and carefully perform the operation.
• Depending on the model, your storage product might look slightly different from the illustrations in this
topic.
• The illustrations in the following procedure show the backplane for 3.5-inch hard disk drives.
To replace the hot-swap hard-disk-drive backplane, do the following:
1. Remove all external media from the drives and turn off all attached devices and the storage product.
Then, disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the storage product.
2. Prepare your storage product. See “Removing or extending the storage product from the rack cabinet”
on page 43.
3. Remove the storage product cover. See “Removing the cover” on page 43.
4. Remove the cooling shroud. See “Removing and reinstalling the cooling shroud” on page 46.
5. Locate the hot-swap hard-disk-drive backplane. See “Storage product components” on page 19.
6. Remove all the installed hot-swap hard disk drives and dummy trays (if any) from the hard-disk-drive
bays. See “Installing or replacing a hot-swap hard disk drive” on page 86.
7. Record the cable connections on the backplane and then disconnect all the cables from the backplane.
8. Press the two latches 1 in the direction as shown until the latches are disengaged from the chassis.
Carefully lift the backplane straight up a little bit so that the small hooks on the chassis are aligned with
the corresponding holes in the backplane. Then, move the backplane to the rear of the chassis to
release the backplane from the hooks.
