Rack-Mounting Guidelines
Caution If the rack is on wheels, ensure that the brakes are engaged or the rack is otherwise stabilized.
Caution If installing this kit in an EIA rack, attach the switch to all four rack-mounting rails; the EIA rails may
not be thick enough to prevent flexing of the shelf brackets if only two rails are used.
Before rack-mounting the chassis, ensure that the cabinet or rack meets the following requirements:
• The specifications listed in the “Cabinet and Rack Requirements” section on page A-1.
• The depth of the rack between the front and rear mounting rails is at least 18 in. (45.7 cm) but less
than or equal to 30 in. (76.2 cm). This is specific to four-post EIA cabinets or racks.
• The airflow and cooling are adequate and there is sufficient clearance around the air vents on the
switch, as described in Appendix B, “Technical Specifications.” This is particularly important to
verify if you are installing the switch in an enclosed cabinet.
• The rack has sufficient vertical clearance for the chassis plus two rack units for the shelf brackets,
and any desired clearance for the installation process.
• The rack meets the minimum rack load ratings per rack unit (RU) listed in the following table.
