Rack-Mounting Guidelines
The switch is designed to be installed in standard 19-inch racks.
Note
Before rack-mounting the switch, ensure that the equipment rack complies with the following guidelines:
• The width of the rack, measured between the two front-mounting strips or rails, must be one of the
following measurements:
• 17.5 inches (44.45 cm)
• 17.75 inches (45.09 cm)
• The depth of the rack, measured between the front- and rear-mounting strips, must be at least 19.25
inches (48.9 cm).
• The rack must have sufficient vertical clearance to insert the chassis: 8.75 inches (22.23 cm) (5 RU)
Chassis height is sometimes measured in rack units (RU or just U) where 1 RU or 1 U equals 1.75 in (44.45
mm). A typical server rack is 42 RU or 42 U in height.
Note
If the rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.
