Facility requirements To ensure correct operation of the switch, the facility where the switch is in use must meet the requirements listed in Table 11. Table 11. Facility requirements Type Electrical Thermal Cabinet (when rack-mounted) Requirements v Primary AC input 100-240 VAC, 2.0A, 47-63 Hz; switch autosenses input voltage v Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the switch nameplate v Correctly wired primary outlet, with circuit protected by a circuit breaker and grounded in accordance with local electrical codes v A minimum air flow of 24 cubic ft/min available to the air intake vents on the nonport side of the switch. v Ambient air temperature not exceeding 40° C (104° F) while the switch is operating v At a minimum, adequate cooling requires that you install the switch with the nonport side, which contains the air intake vents, facing the cool-air aisle v All equipment in the rack should force air in the same direction to avoid intaking exhaust air v Ensure that airflow and temperature requirements are met on an ongoing basis, particularly if the switch is installed in a closed or multicabinet assembly v One rack unit in a standard EIA 19-in. (48.3 cm) cabinet v All equipment in cabinet grounded through a reliable branch circuit connection and maintain ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip v Additional weight of switch not to exceed the cabinet's weight limits v Cabinet secured to ensure stability in case of unexpected movement, such as an earthquake 34 SAN24B-4 Express Installation, Service, and User Guide
