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 29 on page 60 provides the required environmental conditions for normal switch
operation.
Tolerance
No performance degradation to 10,000 feet (3048 meters)
Normal operation ensured in relative humidity range of 10% through
85%, noncondensing
Normal operation ensured in temperature range of 32° F through
104° F (0° C through 40° C)
Guidelines
If your site is susceptible to problems with electromagnetic
compatibility (EMC), particularly from lightning or radio
transmitters, seek expert advice.
Some of the problems caused by strong sources of
electromagnetic interference (EMI) are:
Destruction of the signal drivers and receivers in the switch
Electrical hazards as a result of power surges conducted
over the lines into the equipment
