Upgrading Firmware By Tftp - Ovislink IWE3200-H User Manual

To back up configuration of the access Router by HTTP:
1. Click Back Up.
2. You'll be prompted to open or save the configuration file. Click Save.
3. The configuration file is named by the IWE3200-H's MAC address. For example, if the
IWE3200-H's MAC address is 00-01-02-33-44-55, the configuration backup file should be
"000102334455.hex". Don't change the configuration file name in the Save As dialog box. Se-
lect a folder in which the configuration file is to be stored. And then, click Save.
The procedure may be a little different with different Web browsers.
NOTE:
To restore configuration of the access Router by HTTP:
1. Click Browse and then select a correct configuration .hex file. You have to make sure the file
name is the access Router's MAC address. The firmware file path will be shown in the Firm-
ware file name text box.
2. Click Restore to upload the configuration file to the access Router.

2.10.3.3. Upgrading Firmware by TFTP

When use TFTP as the firmware management protocol, you can configure settings for the access
Router's TFTP client to communicate with a TFTP server. If the TFTP client does not get a response
from the TFTP server within a period specified by the Timeout setting, it will resend the previous
request. The Max number of retries setting specifies the maximal number of resend before the TFTP
client stops communicating with the TFTP server.
Within the folder "Utilities" on the companion CD-ROM disk, we offered a TFTP server program
(TftpSrvr.exe) for firmware upgrade. Run this program on the computer that is to serve as a TFTP
server.
