The switch must be installed in a rack or cabinet housed in a dry, clean, well-ventilated,
and temperature-controlled environment.
Ensure that these environmental guidelines are followed:
The site must be as dust-free as possible, because dust can clog air intake vents and
filters, reducing the efficiency of the switch cooling system.
Maintain ambient airflow for normal switch operation. If the airflow is blocked or
restricted, or if the intake air is too warm, the switch might overheat, leading to the
switch temperature monitor shutting down the switch to protect the hardware
components.
Table 23 on page 56 provides the required environmental conditions for normal switch
operation.
Tolerance
No performance degradation to 10,000 ft (3048 m)
Normal operation ensured in relative humidity range of 10% through
85%, noncondensing
Normal operation ensured in temperature range of 32° F through
113° F (0° C through 45° C)
Complies with Zone 4 earthquake requirements as per GR-63,
Issue 3.
NOTE: Install J-EX Series switches only in restricted areas, such as dedicated
equipment rooms and equipment closets, in accordance with Articles 110–16,
110–17, and 110–18 of the National Electrical Code, ANSI/NFPA 70.
