Description
Allows user to enable or disable per port PD Alive Check
function. By default, all ports are disabled.
This 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+ Managed Injector Hub.
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 2 seconds to 300 seconds.
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.
Allows user to set which action will be applied if the PD is
without any response. The PoE+ Managed Injector Hub
Series offers the following 3 actions:
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+ Managed Injector Hub. 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.
