Mounting The Assembly Kit - AOpen Fortress 1120 User Manual

Pay attention to the two letters, L and R, circled in figure below.
When the frontal mounting bracket is placed with the letter L in a
upright position and R upside down, it should be used as a left
mounting bracket, and vice versa.

Mounting the assembly kit

The Fortress 1120 server can be set up in rack mount fashion using
either the DataCenter Rack or a standard rack assembly kit.
DataCenter Rack
For mounting the rack model in the DataCenter Rack, a support
bracket must first be mounted on the rear left support upright of the
rack.
