Table 32   Troubleshooting the Web Configurator

I cannot access the 

web configurator.

Your computer’s and the Prestige’s IP addresses must be on the same subnet.
Your computer’s IP address must be on the same subnet as the Prestige’s 

Ethernet IP address or management IP address (whichever you want to use to 

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

then enter the new one as the URL.
If you have switched from managing one Prestige 2002 to another, your 

computer’s ARP (Address Resolution Protocol) table may contain an entry that 

maps the management IP address to a different Prestige 2002’s MAC address). 
In Windows, use arp -d at the command prompt to delete all entries in your 

computer’s ARP table.  Otherwise, you can use arp -d inet_addr [if_addr] 

(where if_addr is the Prestige 2002’s management IP address) to remove just the 

entry for the Prestige 2002’s management IP address.

I access the wrong 

Prestige 2002 when 

using the 

management IP 

address to access 

the Prestige 2002. 

This problem may occur if you have more than one Prestige 2002 on the same 

LAN. Disconnect your Prestige 2002 from the network and connect directly 

through the Prestige 2002’s PC port. You may also need to delete your 

computer’s ARP table entry for the Prestige 2002’s IP address (see above).

Table 33   Troubleshooting Telephone

The telephone port 

won’t work or the 

telephone lacks a 

dial tone.

Check the telephone connections and telephone wire.
Make sure you have the VoIP screen properly configured.
