To help prevent serious injuries, load the components in the storage cabinet in the
prescribed order:
1. If present, install the rack stabilizer plate to the front of the system cabinet.
2. Load the Fibre Channel (FC) switches in the storage cabinet at the positions
recommended in the System Installation Guide. The positions can be adjusted
according to a specific storage cabinet configuration.
3. Load and position the server(s) directly above the FC switches, if used in your
configuration.
4. The System Management Unit (SMU), if used in your configuration, should be
placed directly below the FC switches.
5. The first storage enclosure should be positioned at the bottom of the storage
cabinet. Additional enclosures are then placed above existing enclosures, going
towards the top of the system cabinet.
6. Once the bottom half of the storage cabinet has been filled, the top half of the
storage cabinet can be filled. Begin by placing a storage component directly above
the server and then fill upwards.
