Laser precautions
DANGER
All fiber-optic interfaces use Class 1 lasers.
DANGER
Laser Radiation. Do Not View Directly with Optical Instruments. Class 1M Laser Products.
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 60825 and EN60825. 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 3 Facility requirements
Type Requirements
Device specifications Ensure that the facility can accommodate system, power, and environmental specifications for this device as
outlined in the
Brocade X6 Directors Technical Specifications on page 225.
Electrical Ensure that there are dedicated electrical branch circuits with the following characteristics are available:
• Two branch circuits are highly recommended to power supplies for high availability and maximum
blade usage.
• Two cables for VAC high line or VAC low line operation.
• Two cables for DC operation.
• Protected by a circuit breaker in accordance with local electrical codes.
• Supply circuit, line fusing, and wire size adequate to the electrical rating on the chassis nameplate.
• Location close to the chassis and easily accessible.
• Grounded outlets installed by a licensed electrician and compatible with the power cords.
Ensure that all equipment in rack is grounded through a reliable branch circuit connection.
Make sure that power distribution units (PDUs) can handle maximum input amperage of power supplies. Use
cables with adequate amperage rating from PDUs to power source.
Thermal Ensure that the air intake and exhaust vents have a minimum of 5.1 cm (2 in.) of airspace.
Ensure that the air intake temperature is less than 40°C (104°F) during operation.
Rack (when rack-mounted) Ensure that these airflow requirements are met:
• Plan to install the device with the air-intake side facing the cool air aisle. The device can be installed
facing either direction if serviceability and cooling requirements are met.
• Ensure that the airflow available at the air vents meets the minimum requirements for the device.
• Install the device with the airflow aligned with other devices in the rack. Some devices have airflow
running from port side to nonport side and others have the opposite arrangement. Make sure that the
airflow for all devices moves in the same direction to maximize cooling.
Ensure that the following amount of space is available in the rack:
• 8 rack units (8U) high. 1U is equal to 4.45 cm (1.75 inches).
• 9 rack units (9U) high, if you use the airflow diversion rack mount kit.
• 61.29 cm (24.09 inch) deep.
• 43.74 cm (17.22 inch) wide.
