10.2TFTP Firmware Update on the AES-100

The AES-100 uses TFTP for firmware updates through its built-in TFTP server when the AES-100 is operational. To update the firmware, first download it from the ZyXEL web site and store it on your computer. You can use any TFTP client to connect to the AES-100. The procedure for TFTP update is similar to the procedure for restoring configuration.

Do not turn off the AES-100 during the updating process, as it may corrupt the firmware and make your

AES-100 unusable.

To update firmware by TFTP, the procedure is as follows:

Connect to the AES-100 with your favorite TFTP client. The command is generally

tftp <AES-100 IP address>

at the computer command prompt. Step 2. Set the binary mode.

tftp> binary

Step 3. Transfer control files and firmware file to the AES-100.

tftp> put tftplock.key

tftp> put tftpupdt.beg

tftp> put 100AS0b4.img image

tftp> put tftpupdt.end

where
tftplock.key =	The file which contains the SNMP write community string (password).
tftpupdt.beg =	An empty file (with no content).
100AS0b4.img =	The firmware file used in the TFTP update.
image =	The firmware file name used in the AES-100 (fixed).
tftpupdt.end =	An empty file (with no content).
Step 4. Quit TFTP.
tftp> quit

Wait for the update to finish and then restart the AES-100
