7 Negative Vport
8 Negative Vport
Pin assignment of PSE
Make sure the twisted pair cable is bound with the standard RJ-45 pin,
especially pins 4, 5, 7 and 8.
If the RJ-45 is bound with the wrong RJ-45 conductors, JetNet
3706/3706f will not recognize the PD and will forward DC 48V power to
the PD, since the switch follows the Alternative B mode.
In the IEEE 802.3af standard documents, it indicates that the PD
should support mode A and B and only receive power from either mode A or mode B.
The following table shows the RJ-45 pin out for the PD.

4.1.5 Backup and Restore
With the Backup command, you can save current configuration files saved in the switch’s flash
to the admin PC or TFTP server. This will allow you to go to the Restore command later, in
order to restore the configuration file back to the switch. Before you restore the configuration
file, you must place the backup configuration file into the PC or TFTP server. The switch will
then download this file back to the flash.
There are 2 modes for users to backup/restore the configuration file, Local File mode and
TFTP Server mode.
Local File mode: In this mode, the switch acts as the file server. Users can browse the target
folder and then type in the file name to backup the configuration. Users can also browse the
target folder and select existing configuration files to restore the configuration back to the
switch.
TFTP Server mode: In this mode, the switch acts as TFTP client. Before you do so, make
sure that your TFTP server is ready. Then type in the IP address of the TFTP Server and
configuration file name.
TFTP Server IP Address: Key in the IP address of your TFTP Server here.
