Interval Time
The time interval of how long the system issues a ping request to the
connected PD to check if the device is dead or alive.
Time range is 10-300 seconds.
Retry Count
This column allows users to set how many times the system retries
issuing a ping request to the PD. After the retries and fails, the
system will carry out the “Action” below.
For example, if “Retry Count” is set to 2, and the system finds the
device dead, the system will retry 2 ping requests. If the 2 retries fail,
the system will carry out the “Action”.
Action
The action taken if the retry count reaches the set number:
 None: No action.
 Alarm: The switch issues an alarm message via Syslog.
 PD Reboot: The switch reboots the PoE port.
 Reboot & Alarm: The switch reboots the PoE port and issue an
alarm message via Syslog.
Reboot Time
Set a reboot time between 30-180 seconds.
Due to many kinds of PDs having different reboot time, please be
aware of how long they will finish booting up.
The system will check the PD again after the reboot time. If you are
unsure of the boot up time, it is recommended to set it longer.
