Before you remove the hard disk drive backplane:
1. Remove the front cover. See “Remove the front cover” on page 139.
2. After noting their locations, remove any hard disk drives that are installed in the lower compute tray. See
“Remove a hard disk drive” on page 140.
3. Remove the lower compute tray. See “Remove a compute tray” on page 123.
4. Remove the fan cage. See “Remove a fan cage (lower tray)” on page 133.
5. Move or remove the storage interposer to access the hard disk drive backplanes. See “Remove a
storage interposer (lower tray)” on page 183.
6. Move cables and harnesses to provide a clear path for accessing the hard disk drive backplanes and
their connectors.
