Rack Mounting the 2E253-49R

Proceed as follows to install the 2E253-49R into a 19-inch rack:

1.There are several mounting holes in the rackmount brackets and the bottom of the chassis. These mounting holes allow each mounting bracket to be adjusted forward or backward to mount the device further into, or out of the rack, depending on the installation requirements. Position the rackmount brackets over the appropriate holes.

2.Locate the four 6-32 x 1/4-inch flathead screws in the rackmount kit. Use these screws to attach the rackmount brackets to the bottom of the 2E253-49R as shown in Figure 3-3.
