NOTE
Cisco 350, 350X and 550X Series Managed Switches, Firmware Release 2.4, ver 0.4
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:
Event
At least one temperature
sensor exceeds the Warning
threshold
At least one temperature
sensor exceeds the Critical
threshold
Cool down period after the
Critical threshold was
exceeded (all sensors are
lower than the Warning
threshold - 2 °C).
Health and Power Fields
To view the device health parameters, click Status and Statistics > Health and Power.
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).
Action
The following are generated:
• SYSLOG message
• SNMP trap
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.
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.
