In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device.
• JavaScripts (enabled by default).
• Java permissions (enabled by default).

Note: Internet Explorer 6 screens are used here. Screens for other Internet Explorer 
versions may vary.

You may have to disable pop-up blocking to log into your device. 

Either disable pop-up blocking (enabled by default in Windows XP SP (Service Pack) 2) or 
allow pop-up blocking and create an exception for your device’s IP address.

Blocker. 

Table 121   Troubleshooting Accessing the Prestige

I cannot 

access the 

Prestige.

The username is “admin”. The default password is “1234”. The Password and 

Username fields are case-sensitive. Make sure that you enter the correct password 

and username using the proper casing.
If you have changed the password and have now forgotten it, you will need to upload 

the default configuration file. This restores all of the factory defaults including the 

password.

I cannot 

access the 

web 

configurator.

Make sure that there is not an SMT console session running.
Use the Prestige’s WAN IP address when configuring from the WAN. Refer to the 

instructions on checking your WAN connection.
Use the Prestige’s LAN IP address when configuring from the LAN. Refer to for 

instructions on checking your LAN connection.
Check that you have enabled web service access. If you have configured a secured 

client IP address, your computer’s IP address must match it. Refer to the chapter on 

remote management for details. 
Your computer’s and the Prestige’s IP addresses must be on the same subnet for LAN 

access.
If you changed the Prestige’s LAN IP address, then enter the new one as the URL.
Remove any filters in SMT menu 3.1 (LAN) or menu 11.5 (WAN) that block web 

service. 
See the following section to check that pop-up windows, JavaScripts and Java 

permissions are allowed.
