3.2.12 Firmware upgrade
CTC Union's ET100R router module may be upgraded whenever new firmware becomes available. The
upgrade process requires a TFTP server. We provide a free TFTP server for Windows in the 'tools' folder of the
CDROM that comes with any ET100R router.
3.2.12.1 Deployment procedures
Before starting to upgrade, please finish the basic setting of the ET100R Ethernet interface.
1. Basic Ethernet interface configuration for ET100R router module.
CLI commands: (must be in enable)
config interface eth1 off
config interface eth1 ip 0 addr 192.168.0.1 netmask 255.255.255.0
config interface eth1 on
2. Setup TFTP server
Connect a PC with IP set on same network as the ET100R (192.168.0.254 in our example). Launch the TFTP server
application and place the ET100R F/W code into the TFTP server root directory.
3. Start to upgrade the ET100R F/W code.
CLI commands: (must be in enable)
upgrade tftp server 192.168.0.254 file Timage.b76 (image.b80 as of this manual's version)
Switch from the console window to that of the TFTP server; the screen should be showing the file transfer taking place.

Restarting system.
The entire process takes about 3 ½ minutes. The router will now reboot normally. It is recommended by our engineers
to repeat the upgrade procedure again.
