allow installation in a 19 inch or 23 inch rack.
Preparation for Mounting
19 Inch Mounting
For 19 inch mounting, the long side of the
mounting bracket is attached to the side of
the shelf. There are three positions to mount
the bracket on the shelf and four positions on
the mounting bracket. The Rack Mounting
Bracket can also be mounted with the flange
at the back. Thus, there are 24 possible
mounting positions for the Rack Mounting
Bracket. Choose a suitable mounting
position for the shelf then, using the provided
10-32 screws and lock washers, attach the
bracket to each side of the shelf. Place the
shelf in position on the rack and, using the
appropriate screws and lock washers, attach
the shelf to the rack. Please note the
hardware (screws) required to mount the
shelf to the rack is not supplied with the 2745
shelf mounting kit.
