Laser precautions
DANGER
All fiber-optic interfaces use Class 1 lasers.
DANGER
Use only optical transceivers that are qualified by Brocade Communications Systems, Inc. and
comply with the FDA Class 1 radiation performance requirements defined in 21 CFR
Subchapter I, and with IEC 825-2. Optical products that do not comply with these standards
might emit light that is hazardous to the eyes.
Facility requirements
Before installing the device, be sure the following facilities requirements are met.
TABLE 4
Facility requirements
Type Requirements
Electrical • Adequate supply circuit, line fusing, and wire size, as specified by the electrical
rating on the switch nameplate
• Circuit protected by a circuit breaker and grounded in accordance with local
electrical codes
Refer to the Technical Specifications at the end of this guide for complete power
supply specifications.
Thermal • A minimum airflow of 79.8 cubic meters/hour (47 cubic ft/min.) available in the
immediate vicinity of the switch
NOTE
Although this airflow may exceed the airflow maximum listed in the device
Technical Specifications, the additional airflow is recommended to pressurize the
inlet (cool isle) side of rack installations relative to the exhaust side to minimize
recirculation of hot air back to the inlet side.
• Ambient air temperature not exceeding 40°C (104°F) while the switch is operating
Rack (when rack-mounted) • One rack unit (1U) in a 48.3 cm (19-inch) rack
• All equipment in the rack grounded through a reliable branch circuit connection
• Additional weight of switch not to exceed the rack’s weight limits
• Rack secured to ensure stability in case of unexpected movement
