Error Conditions

There are four areas where installers can troubleshoot problems before seeking assistance
from the system or LAN administrator:
1. Check both the power and Ethernet wiring for the following conditions:
Whether all components are plugged in correctly.
Check LAN connectivity in both directions to all servers - DHCP, TFTP, HTTP, SIP
Registration Server, DEFINITY®/MultiVantage™.
If the telephone is supposed to be powered from the LAN, ensure that the LAN is
properly administered and is compliant with IEEE 803.3af.
Ensure that the Ethernet complies with Category 5e wiring.
