AOpen Fortress 1120 User Manual page 51

Note: If two Fortress 1120 servers are installed directly on top of
each other in the rack, the support plates in the bottom server will
be mounted into the bottom row of holes, and in the upper server
into the upper row of holes. This guarantees that enough free
space is available between the servers for the leads that are to be
routed.
To secure the telescopic bars to the server
1 Screw the telescopic bar to the front mounting bracket and make
sure the screws go through the three screw holes on the lower
part of the bracket.
