Laser precautions
DANGER
All fiber-optic interfaces use Class 1 lasers.
DANGER
Use only optical transceivers that are qualified by IBM 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 5. Facility requirements
Type
Requirements
Electrical
v
Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on
the switch nameplate
v
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
v
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.
v
Ambient air temperature not exceeding 40°C (104°F) while the switch is operating
Rack (when
rack-mounted)
v
Two rack unit (2U) in a 48.3 cm (19-inch) rack
v
All equipment in the rack grounded through a reliable branch circuit connection
v
Additional weight of switch not to exceed the rack’s weight limits
v
Rack secured to ensure stability in case of unexpected movement
