Replacing the hot-swap hard-disk-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 73. This topic provides instructions on how to replace the hot-swap hard-disk-drive backplane. 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 74 first and carefully perform the operation. • Depending on the model, your server might look slightly different from the illustrations in this topic. • The illustrations in the following procedure show the backplane for server models with 3.5-inch hard disk drives. For the backplane for server models with 2.5-inch hard disk drives, the replacement procedure is similar. • In the following illustrations, system fans are removed in order to make the hot-swap hard-disk-drive backplane clearly visible. To replace the hot-swap hard-disk-drive backplane, 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. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat, clean, and static-protective surface. See the Rack Installation Instructions that comes with the server. 3. Remove the server cover. See "Removing the server cover" on page 75. 4. Locate the hot-swap hard-disk-drive backplane. See "Hot-swap hard-disk-drive backplane" on page 33. 5. 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 127. 6. Note down the cable connections on the backplane and then disconnect all cables from the backplane. 150 ThinkServer RD340 User Guide and Hardware Maintenance Manual
