NOTE:
If a rack shelf is available, you can put the switch on the rack shelf and slide the switch to a position
so that the mounting brackets make close contact with the front rack posts. Then use screws to
secure the mounting brackets to the rack.

Follow these guidelines when you install the switch in a 19-inch rack:
•
The distance between the front and rear posts of the rack must meet the requirements
described in
•
As a best practice, make sure the rack has a minimum depth of 800 mm (31.50 in) so that the
rack door can be closed easily. The distance between the front rack posts and the front and rear
doors must meet the requirements described in

To secure the switch to the rack, you must install not only mounting brackets, but also chassis
rails and slide rails.
