Rack Mounting

For optional rack mounting, do not install the rubber feet. Mount the MVC 121 Plus on a 19"
Universal 1U or Basic rack shelf.
To rack mount the MVC 121 Plus:
1. If rubber feet were previously installed on the bottom of the MVC 121 Plus, remove
them.
2. Mount the MVC on the rack shelf, using two 4-40 x 3/16 inch screws in opposite
(diagonal) corners to secure the unit to the shelf.
Figure 51.
3. Install blank panels or other units on the rack shelf.

Furniture Mounting

2.
If feet were previously installed on the bottom of the cabinet, remove them.
