Step3       When you are finished, click Submit.

For your security, a password is REQUIRED to log onto the AIR-104/204.  If you forget 
the ICC password, the only way to recover is to clear the entire configuration manually 
and return the unit to its original state as shipped from the factory. Unfortunately, this will 
also result in the loss of your entire configuration database; all settings will need to be re-
entered. To clear the configuration manually and restore the password to the default, 
follow these steps: 

Connect a PC to the CONSOLE port of the AIR-104/204.  The procedure is 
outlined in Chapter 2.

Run the terminal emulation software (e.g. HyperTerminal) on the console PC.  
See Chapter 7 for details on the proper settings for the terminal software.

Toggle the power switch on the rear panel of the AIR-104/204 to off, and then 
toggle it back it on again.  In the console PC’s terminal window, the message 
“Loading firmware...” will be displayed.

When the "Ready" message is displayed in the console PC’s terminal 
window, immediately (within one second) press Control-C on the console 
PC’s keyboard.

The AIR-104/204 will undergo a system reset. After the system reset has 
been completed, all settings stored in the AIR-104/204 will return to the 
factory defaults.  In particular, the ICC password once again will become 
“password”.

Keep in mind that anyone can perform this procedure and seriously 

compromise security in your network. Make sure physical access to the AIR-104/
204 is consistent with your security requirements.

Periodically, you may need to upgrade the AIR-104/204’s firmware (firmware is the 
software that controls the AIR-104/204’s operations). Normally, this is done when you 
discover a problem that is resolved in a newer version of the firmware, or when  Acer 
produces an updated version of the firmware which includes new features that you need.  
Otherwise, if you are happy with your current situation, you may not want to upgrade 
even if a new version is available. Please check the Acer Netxus website for information 
about the latest firmware upgrades (the software can be downloaded directly from the 
website):
www.acernetxus.com.tw

The upgrade procedure follows:

Using a web browser, connect to the Internet and acess the Acer Netxus 
website at:
www.acernetxus.com.tw
Following the directions on the website, download the desired version of the 
software and install it in your local PC environment.

Log onto the ICC.  Find the System Tools heading on the ICC Menu, and click 
on System Upgrade.  The System Upgrade screen appears in the main 
window of the ICC browser screen.
