2 Installation and safety considerations Electrical considerations To install and operate the switch successfully, ensure the following: • The primary outlet is correctly wired, protected by a circuit breaker, and grounded in accordance with local electrical codes. • The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating on the switch nameplate. • The power supply standards provided in Table 7, "System power specifications" are met. Environmental considerations For successful installation and operation of the switch, ensure that the following environmental requirements are met: • At a minimum, adequate cooling requires that you install the switch with the intake side, the nonport side of the switch, facing the cool-air aisle. • All equipment in the rack should force air in the same direction to avoid intake of exhaust air. • A maximum of 102 cubic meters/hour (60 cubic feet/minute) and a minimum of 74.8 cubic meters/hour (44 cubic feet/minute) of airflow is available for air intake.??? • The ambient air temperature does not exceed 40°C (104°F) while the switch is operating. Cabinet considerations For successful installation and operation of the switch in a cabinet, ensure the following cabinet requirements are met: • The cabinet must be a standard EIA cabinet. • A cabinet space that is at least one rack unit (1U) high; 4.45 cm (1.75 inches) high and 48.3 cm (19 inches) wide. • The two rack kit options for the Brocade 6505 use rails that are slimmer than standard rails to accommodate the slightly wider chassis. Be sure to use one of these kits. Do not use standard rails to install the Brocade 6505 in a rack; they will not fit with the switch. • The equipment in the cabinet is grounded through a reliable branch circuit connection and maintains ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip. • Airflow and temperature requirements are met on an ongoing basis, particularly if the switch is installed in a closed or multicabinet assembly. • The additional weight of the switch does not exceed the cabinet's weight limits or unbalance the cabinet in any way. • The cabinet is secured to ensure stability in case of unexpected movement, such as an earthquake. Recommendations for cable management The minimum radius to which a 50 micron cable can be bent under full tensile load is 5.1 cm (2 in.). For a cable under no tensile load, that minimum is 3.0 cm (1.2 in.). 6 Brocade 6505 Hardware Reference Manual 53-1002449-01
