Installation

The 2745 requires ½U (0.875 inches) of rack space. The shelf is supplied with mounting brackets and hardware to

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.
