For more information about the 56K LAN Modem, such as frequently asked 
questions and specific technical notes, go to the following URL, 

then bookmark this site for quick and easy access. If you are using the 56K LAN 
Modem custom browser, click Updates from the menu bar.

Refer to the technical support card that was included with your LAN Modem to 
locate the technical support telephone number for your location.

Your 56K LAN Modem has been designed to be user-upgradable. The latest 
firmware for your 56K LAN Modem is available at 

Refer to the Readme file at the same location for instructions about how to 
download firmware.

There are two types of resets you can perform, a normal reset and a factory reset. 

■

A normal reset will leave all user-entered configuration parameters unchanged. 
Any active calls, however, will be terminated. 

■

A factory reset restores the 56K LAN Modem configuration to the factory 
default settings listed in Appendix C. All user-entered parameters are lost.

To reset the 56K LAN Modem, do the following.

1 From the 56K LAN Modem’s home page, select Maintenance.

2 Select the type of reset you would like to perform, normal or factory.

If you are unable to access the LAN Modem’s main page because your computer 
cannot communicate with the LAN Modem, you can restore the LAN Modem to 
the factory default settings using the reset switch located on the unit’s back panel. 
To reset the LAN Modem using the reset switch, do the following.

■

Press and continue to hold in the reset button located on the back of the unit. 
(You must continuously hold the reset button through three cycles of LED 
flashing: Reset, Firmware Download mode, and Factory Default Reset.) 

■

After approximately ten seconds, the ALERT LED will begin to flash. This first 
cycle indicates that the unit has been reset. This first reset is similar to a 
power-cycle of the unit. In this case all user-entered information is maintained. 

■

The second cycle of ALERT LED flashing indicates that the unit has entered 
firmware download mode.

■

After the ALERT LED has flashed for the third cycle, you have successfully reset 
the LAN Modem back to factory defaults. 

■

Release the reset button. 

The LAN Modem reinitializes itself, and is reset back to the factory defaults. All 
user-entered information will be erased.

■

Restart your computer.
