Firmware Upload and Recovery
ZyXEL periodically releases new firmware for the network modules for bug fixes and enhancements.
Please check the web site at www.zyxel.com every now and then for the latest firmware release.
The network modules use FTP to upload firmware and no longer support TFTP uploads. If the firmware in non-
volatile memory is damaged, the network module uses BOOTP/TFTP to recover the firmware. The differences
between these two methods are as follows:
♦ Upload timing:
An FTP upload is done during operation (run-time), while a BOOTP/TFTP recovery is done when the network
module is restarted.
♦ Protocols used:
An FTP upload uses FTP protocol, while a BOOTP/TFTP recovery uses BOOTP and TFTP protocols.
♦ Remote upload:
An FTP upload does not require the network module and your computer to be on the same LAN, while a
BOOTP/TFTP recovery does.
♦ Firmware files used:
An FTP upload uses a file with an “.img” extension name, while a BOOTP/TFTP recovery uses a file with a
“.bin” extension name.
♦ The role of the network module:
An FTP upload uses the network module’s built-in FTP server and a BOOTP/TFTP recovery uses the network
module’s built-in BOOTP/TFTP client.
♦ The impact to the network module:
An FTP upload overwrites the network module’s firmware only while a BOOTP/TFTP recovery overwrites the
network module’s firmware and all configuration files.
14.1 FTP Firmware Upload on the Network Module
The network modules use FTP for firmware uploads through their built-in FTP server when the network module is
operational. To update the firmware, first download it (the file will have an “img” extension name) from the
ZyXEL web site and store it on your computer. You can use any FTP client (for example, ftp.exe in Windows) to
upgrade the network module’s firmware. The procedure for FTP upgrade is as follows.
Do not turn off the network module during the updating process, as it may corrupt the firmware and make
your network module unusable.
1. Connect to the network module with your favorite FTP client.
The command for the SAM1008 is generally: ftp <SAM1008 IP address> at the computer
command prompt.
2.
Enter the user name (just press [ENTER]). For example,
User: <ENTER>
