FIRMWARE UPDATE PROCEDURE.

********* W A R N I N G *********

!!!
!!! NOTE: There are two hardware revisions of DSL-300+ available.
!!! If you modem has "Generation II" printed on the front panel please
!!! use firmware for Generation II modems. Modems NOT marked as Generation II
!!! can NOT use Gen II firmware
!!! 

**********************************


You can update firmware by running the Setup.exe (application file) or by uploading the 
firmware via serial connection (only for versions of modems with 9pin RS-232 serial port).
Please follow the instructions below.



STEP 1. 
Connect your computer DIRECTLY to the modem (do not connect via hubs/switches when 
updating firmware). Do not upgrade the firmware through a router, connect your modem
directly to PC.
Use straight-through cable. Make sure you are getting a link light on the modem on 
the port you have the computer connected to.
Disconnect ADSL cable from the modem.
If you have any Antivirus, Proxy, Firewall software running disable it temporarily.


STEP 2.
Computer setup:
Set your computer to obtain IP address automatically:
You can do this under Control Panel > Network > TCP/IP (linked to your network 
card) > Properties. In Windows XP select Local Area Connection > Properties. Restart PC.

After rebooting check the IP address that you have got:
•  in Win95/98 - go to Start > Run > winipcfg > OK > select your adapter and look 
under IP Address. 
•  in Win2000/XP go to Start > Run > cmd > OK > ipconfig /all > look for IP Address. 
It should be something like 192.168.0.x 

If it is not - do the following: 
in Win95/98 - go to Start > Run > winipcfg > OK > select your adapter and press 
Release All and then Renew All.
in Win2000/XP go to Start > Run > cmd > OK > ipconfig /release (hit Enter) > 
ipconfig /renew (hit Enter)


STEP 3.
Loading firmware.


OPTION A: Using Firmware Upload Utility.
=========
Extract the files into a temporary folder. Then double-click on SETUP.EXE (Application).
If you had Firmware Upload Utility installed before install new utility into a different
folder (change folder name when suggested to use defailt folder).
After installing the Utility run it. It should discover the modem on your network. 
Click on Upgrade button. 
You will be asked to enter password: the default is "admin".

*** DO NOT DISCONNECT POWER FROM THE modem WHILE UPLOADING FIRMWARE ***

=============================
TROUBLESHOOTING:
=============================

If firmware upgrade did not go through successfully for some reason or was interrupted 
do not restart the modem. Just try to reload the firmware again. 

Check if you have any Antivirus, Proxy, Firewall software running (you may need to disable it).

Try a different PC on your network.

If you are experiencing time-out problems when updtating the firmware please ensure that the 
default SNMP community string is present on the modem. You can set it up by issuing the 
following commands at the Command Line Interface of your modem:

snmp access write private
config save


In order to access Command Line Interface connect to the modem using serial cable (using COM
ports on your computer and modem).

Run Hyperterminal (you can find this program in Windows under Start > Programms > Accessories > 
Communication). Create new conection using COM1 or COM2 (whichever port you connected the cable
to). Use the following settings: 9600 baud, 8 bit data word, 1 stop bit, No parity and 
Hardware (CTS/RTS) handshaking.

Press enter and you should get a prompt like
192.168.0.1>


In order to access Command Line Interface you can use also use Telnet. 
In Windows click on Start > Run... and type
telnet 192.168.0.1 (where 192.168.0.1 is modem/modem's IP address. DSL-300 has 192.168.1.1 
address). Click on OK. You will be prompted to enter password. Default password is "private".

If after loading the firmware your modem is not accessible through Internet Explorer: log into the 
modem via Hyperterminal or Telnet as described above, and apply the following commands:

192.168.0.1>config save
192.168.0.1>flashfs update

Flashfs update may take some time, please wait until it finishes. Then just do restart:
192.168.0.1>restart
