Rack-mounting
The Switch 4900 SX is 1.5U and will fit in most standard 19-inch racks.
However, as each Switch requires a shelf or runner to support its weight,
you will need to allow a 2U space within the rack for each Switch.

WARNING: The switch should only be used in a rack if it is mounted on
runners, a shelf, or a tray to support the weight. The rack-mount kits
alone are not sufficient to support the weight of the switch. The rack
mount kits must not be used to suspend the Switch from under a table or
desk, or attach it to a wall.
