Environmental Requirements and Specifications

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 1 provides the required environmental conditions for normal switch operation.

Table 1: EX-series Switch Environmental Tolerances




No performance degradation to 10,000 feet (3048 meters)

Relative humidity

Normal operation ensured in relative humidity range of 5% to 90%, noncondensing


Normal operation ensured in temperature range of 32° F to 104° F (0° C to 40° C)


Complies with Zone 4 earth quake requirements as per GR-63, Issue 3.
