Extreme Networks equipment generates a significant amount of heat. It is essential that you provide a temperature-controlled environment for both performance and safety.
Install the equipment only in a temperature- and humidity-controlled indoor area that is free of airborne materials that can conduct electricity. Too much humidity can cause a fire. Too little humidity can produce electrical shock and fire.
Observe these additional thermal recommendations for the location where you plan to install your equipment:
Thermal Shutdown and Restart Behavior summarizes the behavior of ExtremeSwitching switches when they experience high operating temperatures.
Ambient Temperature Range for Switches lists the ambient temperature range for ExtremeSwitching switches. As with all electrical equipment, however, Extreme Networks product lifetimes degrade with increased temperature. Ideally, therefore, temperatures should be kept at or below 25°C (77°F).
Safeguards are built into all Extreme Networks switches and power supply units to minimize the risk of fire.
| Switch Model(s) | Behavior |
|---|---|
| All models except those listed below | When internal system temperatures exceed the
thermal shutdown temperature limit (typically about 20°C higher than
normal system operating temperatures), the system‘s power supplies are
turned off and the switch shuts down. The system remains in the OFF
state until the system has sufficient time to cool and the internal
thermal sensor measures a temperature lower than the maximum specified
ambient temperature, at which time the system restarts
automatically. Alternately, you can restart the system immediately by removing and then restoring all line power to the system. |
| X460-G2 (all models) |
When internal system temperatures exceed the thermal shutdown temperature limit (typically about 20°C higher than normal system operating temperatures), the system‘s power supplies are turned off and the switch shuts down. The switch does not restart automatically, even after cooling. It remains in the OFF state until you remove and then restore all line power to the system. |
| Switch Series | Ambient Operating Temperature Range |

| X440-G2 | 0°C (32°F) to 50°C (122°F) Note: The maximum temperature is 60°C (140°F) for
the following models: X440-G2-12t8fx-GE4, X440-G2-24fx-GE4,
X440-G2-24t-GE4.
