Figure 4-16-7: PD Alive Check Configuration Screenshot
The page includes the following fields:
Object Description
Allo
ws user to enable or disable per port PD Alive Check function.
By default, all ports are disabled.
 Mode
T
his column 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 with the PoE Switch.
 Ping PD IP Address
 Interval Time (10~300s)
This column 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.
T
his column allows user to set the number of times system retries ping to PD.
For example, if we set count 2, it means that if system retries ping to the PD and the
PD doesn’t response continuously, the PoE port will be reset.
 Retry Count (1~5)
Allo
ws user to set which action will be applied if the PD is without any response. The
PoE Switch Series offers the following 3 actions:
 PD Reboot: It means system will reset the PoE port that is connected to the
PD.
 PD Reboot & Alarm: It means system will reset the PoE port and issue an
alarm message via Syslog.
 Alarm: It means system will issue an alarm message via Syslog.
 A
ction
 Reboot Time (30~180s)
This column allows user to set the PoE device rebooting time as there are so many
kinds of PoE devices on the market and they have a different rebooting time.
The PD Alive-check is not a defining standard, so the PoE device on the market
doesn’t report reboot done information to the PoE Switch. Thus, user has to make
sure how long the PD will take to finish booting, and then set the time value to this
column.
System is going to check the PD again according to the reboot time. If you are not
sure of the precise booting time, we suggest you set it longer.
