Table 38   Troubleshooting the Web Configurator

I cannot access the 

web configurator.

If the Prestige’s Ethernet IP address or management IP address has changed, 

then enter the new one as the URL.
Your computer’s IP address must be on the same subnet as the Prestige’s 

Ethernet IP address or management IP address (whichever you use to access the 

Prestige).
See 

 to check that pop-up windows, JavaScripts and 

Java permissions are allowed.
Ping the Prestige. In the computer, click Start, (All) Programs, Accessories and 

then Command Prompt. In the Command Prompt window, type "ping" followed 

by the Prestige’s IP address (192.168.5.1 is the default management IP address) 

and then press [ENTER]. The Prestige should reply. Otherwise, make sure your 

computer’s Ethernet adapter is installed and functioning properly.
You may also need to clear your Internet browser’s cache.
In Internet Explorer, click Tools and then Internet Options to open the Internet 

Options screen. 
In the General tab, click Delete Files. In the pop-up window, select the Delete all 

offline content check box and click OK. Click OK in the Internet Options screen 

to close it.
If you disconnect your computer from one device and connect it to another device 

that has the same IP address, your computer’s ARP (Address Resolution 

Protocol) table may contain an entry that maps the management IP address to the 

previous device’s MAC address). 
In Windows, use arp -d at the command prompt to delete all entries in your 

computer’s ARP table.

I access the wrong 

Prestige when 

using the 

management IP 

address for access. 

This problem may occur if you have more than one Prestige on the same LAN. 

Disconnect your Prestige from the network and connect directly through the 

Prestige’s PC port. You may also need to delete your computer’s ARP table entry 

for the Prestige’s IP address (see above).

Table 39   Troubleshooting the Password

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 

restore the default configuration file (see 

). This restores 

all of the factory defaults including the password.
