8 IP 8000 Product Information

Inspect connections to any system cables and ensure there are no obstructions or loose

cables at either end. Ensure you have connected the network cable correctly to the PoE

adapter, wall port, or interface module. Although it is possible to plug in the LAN end to the

phone, the phone will not work. Correct the connection by reversing the cable to obtain

connectivity to your phone.

IP Address Displays Invalid Value

If the IP address displays an invalid value, or the address on the Main Menu displays as

http://0.0.0.0, one of the following conditions may be occurring:

Poor Quality Display

If you have poor quality or unreadable data on the display, adjust the LCD Contrast setting

(from the Preferences - User menu). The default setting is recommended.

Display Failures

If data does not appear on the phone display, ensure the unit is properly plugged into a PoE

connection. Ensure that the Ethernet connector is fully engaged into the RJ-45 jack on the

underside of the phone. Also ensure that your Ethernet wall jack connection is PoE

(standard Ethernet has no power) for IP use. A bad Ethernet cable connection may also

result in display failures; replace it with a high-quality Ethernet cable.

Absent Dial Tone

If you do not receive a dial tone after pressing the or key to initiate a call, ensure

the speaker volume is adjusted appropriately.

An absent dial tone may also result from an unavailable analog phone line connection.

Condition Resolution

The unit is configured to obtain an address

using DHCP and no DHCP server is

available.

Verify that the unit is plugged into a network that has a DHCP

server present.

Faulty Ethernet cable connection. Replace the Ethernet cable with a high quality cable.

The unit is configured to use a static IP

address, but no IP address has been

entered in the address field.

Identify and enter the necessary IP information if you disable

DHCP.

Network connection is unavailable. An IP address such as 0.0.0.0 or 169.254.x.y is invalid for IP

configurations, and you cannot access the web configuration

since there is no network access.
