4.5.6 PoE Alive Check Configuration
The WGR-500 Series can be configured to monitor connected PD’s status in real-time via ping action. Once the
PD stops working and without response, the WGR-500 Series is going to restart PoE port port power, and bring
the PD back to work. It will greatly enhance the reliability and reduces administrator management burden. The
PoE Alive Check setup is shown in Figure 4-51

Object Description
Mode Allows user to enable or disable PD Alive Check function. The default is disabled.
Remote PD
IP Address
Allows user to set PoE device IP address for system making ping to the PoE device.
Please note that the PD’s IP address must be set to the same network segment as the
industrial wall-mount Gigabit router. The default is 60s.
Interval Time
(10~300s)
Allows user to set how long system should issue a ping request to PD for detecting
whether PD is alive or dead. Interval time range is from 10 seconds to 300 seconds.
Retry Count
(1~5)
Allow user to set how many times system wants to retry ping to PD. For example, if we
set count 2, the meaning is that if system retries ping to the PD and the PD doesn’t
response continuously, the PoE port will be reset. The default is 2.
Action Allow users to set which action will be applied if the PD is without any response. The
industrial wall-mount Gigabit router offers 4 actions as follows:
None: no action. The default is None.
PD Reboot: system will reset the PoE port that is connected to the PD.
PD Reboot & Alarm: system will reset the PoE port and issue an alarm message via
syslog.
Alarm: system will issue an alarm message via syslog.
Reboot Time
(30~180s)
Allows user to set the PoE device rebooting time.
The PD alive check is not a defining standard, so the PoE device on the market doesn’t
report reboots done information to the system. User has to make sure how long the PD
will be finished to boot, and set the time value to this column. If you cannot make sure
the precise booting time, we suggest you set it longer. The default is 60s.
