AP-5131 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 AP-5131 (since the LAN Port is a DHCP Client,
out-of-the-box auto update support is on the LAN Port).
4. Restart the AP-5131.
5. While the AP-5131 boots, verify the AP-5131:
• 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 AP-5131 System Settings screen.
Whenever a configuration file is specified, the AP-5131 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 AP-5131 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 AP-5131 uses the entire bf field
as the config file name.
NOTE The bf option prefixes a forward slash (/) to the firmware file name. This
may not be supported on Windows based TFTP Servers.
