Chapter 16
Firmware Upload and Recovery
This chapter describes how to load new firmware onto your line card, or recover firmware that is in the
non-volatile memory.
The ALC1024 and SLC1024 line cards use FTP to upload firmware. If the firmware in non-volatile memory is
damaged, the line card uses BOOTP/TFTP to recover the firmware. The differences between these two methods
are as follows:
Table 16-1 FTP Upload and BOOTP/TFTP Recovery Differences
FTP UPLOAD
BOOTP/TFTP RECOVERY
Upload Timing:
Done during operation (run-time).
Done when the line card is restarted.
Protocols Used:
Uses FTP protocol.
Uses BOOTP and TFTP protocols.
Remote Upload:
Does not require the line card and your
computer to be on the same LAN.
Requires the line card and your computer
to be on the same LAN.
Firmware Files Used: A file with an “.img” extension name.
A file with a “.bin” extension name.
Role of the Line
Card:
Uses the line card’s built-in FTP server.
Uses the line card’s built-in BOOTP/TFTP
client.
Impact to the Line
Card:
Overwrites the line card’s firmware only.
Overwrites the line card’s firmware and all
configuration files.
16.1 FTP Firmware Upload on the Line card
ZyXEL periodically releases new firmware. Please check
www.zyxel.com
periodically for the
latest firmware release.
The line cards use FTP for firmware uploads through their built-in FTP server when the line card 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 line
card’s firmware. The procedure for FTP upgrade is as follows.
Do
not
turn off the line card during the updating process, as it may corrupt the firmware and
make your line card unusable.
1.
Connect to the line card with your favorite FTP client.
The command for the ALC1024 or SLC1024 is generally:
ftp <line card IP address>
at the
computer command prompt.
2.
Enter the user name (just press [ENTER]). For example,
User: <ENTER>
3.
Enter the management password (1234 by default). For example,
Password: 1234
230 Logged in
4.
Transfer the firmware file to the line card. For example,
