Cisco 350XG & 550XG Series 10G Stackable Managed Switches
The Health page monitors the temperature status, power supply status and fan
status on all devices with fans. Depending on the model, there are one or more
fans on a device. Some models have no fans at all.
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).
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.
