The Health page displays the following fields:
• Fan Status—Fan status. The following values are possible:
- OK—Fan is operating normally.
- Fail—Fan is not operating correctly.
- N/A—Fan ID is not applicable for the specific model.
• Fan Direction—(On relevant devices) The direction that the fans are
working in (for example: Front to Back).
• Temp erature—The options are:
- OK—The temperature is below the warning threshold.
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.
