AP-51xx Access Point Product Reference Guide
B-8
Using options sa, bf and 136:
3. Copy the firmware and configuration files to the appropriate directory on the TFTP Server.
By default, auto update is enabled on the access point (since the LAN Port is a DHCP Client,
out-of-the-box auto update support is on the LAN Port).
4. Restart the access point.
5. While the access point boots, verify the access point:
• Sends a true BootP request.
• Obtains and applies the expected IP Address from the BootP Server.
• Downloads both the firmware and configuration files from the TFTP Server and updates
them as required. Verify the file versions within the System Settings screen.
Whenever a configuration file is specified, the access point will tftp the config file, parse it
and use the firmware file name in the config file.
If T136 is provided by the server, the access point strips off the TFTP root directory from the
fully qualified configuration file name to obtain a relative file name. For example, if using
bf=/opt/tftpdir/ftp/dist/ap.cfg and T136="/opt/tftpdir", the config file name is
ftp/dist/ap.cfg. T136 is only used for this purpose. It is NOT used to append to the config file
name or the firmware file name. If T136 is not specified, the access point uses the entire bf
field as the config file name.
NOTE The bf option prefixes a forward slash (/) to the configuration file name.
The forward slash may not be supported on Windows based TFTP Servers.
NOTE The update process is conducted over the LAN or WAN port depending on
which Server responds first to the access point’s request for an automatic
update.
