User’s Manual of GS-4210 Series
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.
Retry Count (1~5)
This 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.
Action
Allows 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.
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.
