2. The IP telephone sends a request to the DHCP server and invokes the DHCP process.

One of the following messages display:

 

where s is the number of seconds that have elapsed since DHCP was invoked. The 
message on the left appears if 802.1Q tagging is off and access to local programming 
procedures is not disabled or restricted. (See 

 for 

specifics.) The middle message appears if 802.1Q tagging is on and access to local 
programming procedures is disabled or restricted. If the left and middle messages alternate 
every two seconds, 802.1Q tagging is on. When both messages alternate, access to local 
programming procedures is not disabled or restricted. Finally, the message on the right 
appears if 802.1Q tagging is off and access to local programming procedures is disabled or 
restricted.

3. The DHCP server provides IP addresses for the following hardware:

●

The IP telephone

●

The TFTP or HTTP server

●

The TN799B, C, or D Control-LAN (CLAN) circuit pack on the media server

The 4601 cannot display messages. Therefore, if the DHCP process locates the required 
information, the 4601’s Call Appearance Line b indicator flashes continuously 500 
milliseconds on, 500 milliseconds off while all other LEDs remain lit. If the appropriate 
information cannot be discerned or is missing, the 4601’s Call Appearance Line a indicator 
flutters 50 milliseconds on, 50 milliseconds off three times while all other LEDs remain lit, 
and a reset occurs.

4. Using the list of gateway IP addresses provided by the DHCP server, the phone performs a 

router check. The phone cycles through the gateway IP addresses with ARPs or pings until 
it receives a response. During this search, the 4601’s Call Appearance Line b indicator 
flashes continuously 500 milliseconds on, 500 milliseconds off. All other 4601 LEDs remain 
lit. 

When the router is located, the TFTP or HTTP process starts. If no router is found for a 
4601 IP Telephone, its Call Appearance Line b flutters 50 milliseconds on, 50 milliseconds 
off three times. All other 4601 LEDs remain lit, and a reset occurs.
