This section describes the rack mounting instructions for the 12200 and 12300:
Four Post Standard-Depth Rack Installation
In a standard-depth rack, the distance between the front and back mounting posts
is ~28" (700mm). Mounting rails for the 12200 and 12300 are adjustable to
accommodate racks with 26"-33" between mounting posts.

 One pair of mounting rails adjustable for 26"-33" installation range
 One pair of hat rails, left and right
 #6-32 screws
 M6 cage nuts
 M6 screws
Installation
1. Install the hat rails on each side of the switch using three (3) #6-32 screws
per rail. Torque screws to 8in-lb. A typical installation is shown in Figure 1-3..
On the 12300, hat rails are installed with mounting ears towards the power
supply side of the switch. On the 12200, hat rails are installed with mounting
ears towards the port side of the switch. Additionally, 12200 switches can be
installed recessed within a rack. There are four sets of mounting holes on
hat rails, for recess installations of 0, 2, 3 or 4 inches. Use the appropriate
mounting holes to achieve the desired recess.
