DANGER
Use only optical transceivers that are qualified by Broadcom and that 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 chassis and addressing facility requirements, you must earth-ground the switch chassis using one of
the following two methods:
•
Through the chassis rack ear mounts to a grounded data center rack. All equipment in the rack is grounded through a
reliable branch circuit connection.
•
Through an explicit ground cable. The chassis is grounded through a ground cable using the threaded ground lug
connection on the nonport side of the chassis. See item 2 in the following figure.

After you have grounded the chassis, ensure that the following requirements are met.
Table 4: Facility Requirements
Type Requirements
Electrical
•
An adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the switch
nameplate.
•
A circuit that is protected by a circuit breaker and grounded in accordance with local electrical codes.
See Technical Specifications for power supply specifications.
Thermal
•
A minimum air flow of 170 Cubic meters/hour (100 cubic feet/minute) available in the immediate
vicinity. Although this airflow may exceed the airflow maximum that is 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 in.) rack.
•
All equipment in the rack grounded through a reliable branch circuit connection.
•
The additional weight of the switch not to exceed the weight limits of the rack.
•
Rack secured to ensure stability if there is unexpected movement.
