10.2 TFTP 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:
Step 1. 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
