Upgrading Firmware
1. Disconnect the JetNet from the network, but keep the JetNet connected with the TFTP
server.
2. Set the DIP Switches to the settings as follows:
For JetNet 3505: RM = On, P4 = On, P2 =On, P5 = OFF, P3 = OFF, P1 = OFF.
For JetNet 3508: RM = On, P8 = Off, P7 = Off, P5 = Off, P4 =On, P3 = OFF, P2 = On, P1 =
OFF.
3. Set your TFTP server IP as 192.168.10.250, which is the dedicated TFTP server IP set up in
the JetNet.
4. Press the reset button for 5 seconds, and then the PWR1 and PWR2 LEDs will start to flash,
showing that TFTP firmware is being upgraded. The JetNet will automatically search for the
TFTP server, and update the firmware. Make sure the connection between the JetNet and
the TFTP server is intact when the firmware is being upgraded.
5. If any error occurs during the upgrading process, the FAULT LED will flash.
Note
