NOTE:
The LAN IP address of the HD24613 and the IP address of the TFTP server must be in the
same IP subnet for TFTP to work.
NOTE:
Due to the unreliable nature of wireless media, it’s highly recommended that the TFTP server
and the to-be-upgraded wireless HD24613 be connected by Ethernet, and on the same LAN, so that
the upgrade process would be smooth.
NOTE:
After the firmware is upgraded, be sure to delete the contents of the Web browser cache, so
that the Web management pages can be shown correctly.
NOTE:
A failed upgrade may corrupt the firmware and make the HD24613 unbootable. When this
occurs, call for technical support.
TIP:
If you want to remotely upgrade the firmware of a deployed HD24613 from the Internet, adjust
the
Timeout
and
Max no. of retries
settings of TFTP Server for remote TFTP upgrade to succeed.
3.3.3.4. Backing up and Restoring Configuration Settings by TFTP
Fig. 25. Configuration backup/restore
To back up configuration of the HD24613 by TFTP:
1.
Get a computer that will be used as a TFTP server and as a managing computer to trigger the
backup process.
2.
Connect the computer and one of the LAN Ethernet switch port with a normal Ethernet cable.
3.
Configure the IP address of the computer so that the computer and the HD24613 are in the same
IP subnet.
4.
On the computer, run the TFTP Server utility. Select the
Accept write requests
check box, and
specify the folder to which the configuration settings of the HD24613 will be saved.
5.
On the computer, run a Web browser and click the
General, Firmware
Tools
hyperlink.
6.
Choose
TFTP
as the
Firmware management protocol
.
7.
Within the
Configuration Backup/Restore
section, specify the IP address of the computer,
which acts as a TFTP server. If you don’t know the IP address of the computer, open a Com-
mand Prompt, and type IpConfig, then press the
Enter
key.
8.
Trigger the backup process by clicking
Back Up
. The HD24613’s configuration settings will be
saved as “
AaBbCcDdEeFf.hex
” by the TFTP server, where “AaBbCcDdEeFf” is the AP’s
MAC address. For example, if the AP’s MAC address is 00-01-02-33-44-55, the configuration
backup file will be “000102334455.hex”.
NOTE:
Remember to select the
Accept write requests
check box of TFTP Server.
