Installation Prerequisites
For the installation to proceed without interruption, it is important that you verify that you have all
necessary materials on hand.
A TMG7800 system can range in size from 2 to 22U in vertical rack space, at full capacity with
redundant N+1 patch panels. In addition, if your system is configured to use multiple groups of 1+1
patch panels, the total vertical rack space may exceed 22U.

7800-CTRL
For information about the 7800-CTRL, refer to Dell’s documentation:

Adequate space for the installation of the 7800-CTRL
You must mount the 7800-CTRL on a 19" equipment rack (customer provided). Your 7800-CTRL
is a
1U unit. Plan for an additional 1U space on the equipment rack for a redundant 7800-CTRL.
Note
The depth of the 7800-CTRL is greater than the 16” (406mm) depth of the 7800 series
telecom units. It is important to plan for an equipment rack of adequate size.
