Some devices have a temperature sensor to protect its hardware from overheating. In this case, 
the following actions are performed by the device if it overheats and during the cool down 
period after overheating:
Health and Power Fields
To view the device health parameters, click Status and Statistics > Health and Power.
NOTE Only fields that are relevant to the device are displayed.
This section displays the power saved by the device due to the Green Ethernet and Led Disable 
features, as well as due to ports being down (physically or due to time range settings).
Event Action
At least one temperature 
sensor exceeds the Warning 
threshold
The following are generated:
• SYSLOG message
• SNMP trap
At least one temperature 
sensor exceeds the Critical 
threshold
The following are generated:
• SYSLOG message
• SNMP trap
The following actions are performed:
• System LED is set to solid amber (if hardware 
supports this).
• Disable Ports — When the Critical temperature 
has been exceeded for two minutes, all ports will 
be shut down.
• (On devices that support PoE) Disable the PoE 
circuitry so that less power is consumed and less 
heat is emitted.
Cool down period after the 
Critical threshold was 
exceeded (all sensors are 
lower than the Warning 
threshold - 2 °C). 
After all the sensors cool down to Warning Threshold 
minus 2 degree C, the PHY will be re-enabled, and all 
ports brought back up.
If fan status is OK, the ports are enabled.
(On devices that support PoE) the PoE circuitry is 
enabled.
