Ensure that the area where you install your switch meets the following safety requirements:
• Near an adequate power source. Connect the switch to the appropriate branch circuit
protection according to your local electrical codes.
• Environmental—switch location—continuous temperature range is from 0°C to 45°C
(32°F to 113°F).
• Operating humidity is from 5 to 90 percent non-condensing, continuous.
• In a dry, clean, well-ventilated, and temperature-controlled room, away from heat
sources such as hot cooling vents or direct sunlight.
• Away from sources of severe electromagnetic noise.
• Positioned in a rack or cabinet, or on a desktop with adequate space in the front, back,
and sides for proper ventilation and access.
• Install the switch in Information Technology Rooms in accordance with Article 645 of
the National Electrical Code and NFPA 75.

Specications.
Cabinet placement
Install the Z9264F-ON switch only in indoor cabinets designed for use in a controlled
environment.
Do not install the switch in outside cabinets. For cabinet placement requirements, see Site
selection.
The cabinet must meet minimum size requirements. Airow must be in accordance with the
Electronic Industries Alliance (EIA) standard. Ensure that there is a minimum of 5 inches
(12.7 cm) between the intake and exhaust vents and the cabinet wall.
Rack mounting
When you prepare your equipment rack, ensure that the rack is grounded. Ground the
equipment rack to the same ground point the power service in your area uses. The ground
path must be permanent.
