• When the temperature drops below the lower threshold or reaches the warning threshold, the
device logs the event and outputs a log message and a trap.
• When the temperature reaches the alarming threshold, the device logs the event and outputs a log
message and a trap repeatedly in the terminal display, and alerts users through the LED on the
device panel.
Due to temperature hysteresis, a temperature decreasing notification is later than the actual temperature
decreasing event. Fan speed changes might cause the actual temperature value read after an alarm to
be lower than the alarm temperature.
To configure temperature thresholds:

The warning and alarming thresholds
must be higher than the lower

The alarming threshold must be higher
than the warning threshold.

Typically, the device does not send notifications to its NMS when the IP address of an interface changes.
If the IP address of the interface used by the device to communicate with the NMS changes, the NMS will
be unable to communicate with the device unless the new management IP address of the device is
manually updated or the device is re-added with the new IP address to the NMS database.
To ensure management continuity, you can configure the device to monitor the NMS connected interface
for IP address changes and notify the NMS to update with the new IP address for communicating with the
device.
You can configure one primary and one secondary interface for the device to communicate with the
NMS, but the device monitors only one of them for IP address change at one time. If the IP address of the
monitored interface in UP state changes, whether because of manual reassignment or DHCP
reassignment, the device notifies the NMS of the new IP address. The IP address changes of the interface
not under monitor will be ignored.
