4600 Series IP Telephone Installation
For the 4601 only, all the 4601's LED indicators illuminate to indicate system value
initialization. When system value initialization completes, the 4601's Call Appearance Line a
flashes continuously 500 milliseconds on, 500 milliseconds off while all other LEDs remain
lit.
Note:
The Ethernet speed indicated is the LAN interface speed for both the telephone

and any attached PC.
2. The IP telephone sends a request to the DHCP server and invokes the DHCP process.
One of the following messages display:
DHCP: s secs
# to program
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
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 (for IP
●
telephones supporting H.323 protocol)
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 telephone
performs a
router check. The telephone 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.
