Chapter 3 Setting Up the Cisco Unified IP Phone
Verifying the Phone Startup Process
2. Some or all of the line keys flash orange.
Caution If the line keys flash red in sequence after flashing yellow, do not power down the
phone until the sequence of red flashes completes. This sequence can take several
minutes to complete.
3. Some or all of the line keys flash green.
Normally, this sequence takes just a few seconds. However, if the phone’s
Flash memory is erased or the phone load is corrupted, the sequence of green
flashes will continue while the phone begins a software update procedure. If
the phone performs this procedure, the following buttons light to indicate
progress:
– Headset—Phone is waiting for the network and completing CDP and
DHCP configuration. (A DHCP server must be available in your
network.)
– Mute—Phone is downloading images from the TFTP server.
– Speaker—Phone is writing images to its Flash memory.
4. The LCD screen displays the Cisco Systems, Inc., logo screen.
5. These messages appear as the phone starts:
– Verifying load (if the phone load does not match the load on the TFTP
server). If this message appears, the phone start up again and repeats step
1 through step 4 above.
– Configuring IP.
– Updating CTL.
– Updating Locale.
– Configuring CM List.
– Registering.
