page 85.
CAUTION: To prevent damage to the drives and backplane, you must remove the
hard drives from the system before removing the backplane.
CAUTION: You must note the number of each hard drive and temporarily label
them before removal so that you can replace them in the same locations.

inch hard drives.
Note the routing of the cable underneath the tabs on the chassis as you

when you replace them to prevent the cables from being pinched or
crimped.

5-12.
Note the routing of the cable underneath the tabs on the chassis as you
