After the Cisco Unified IP Phone has power connected to it, the phone begins its startup process by
cycling through the following steps.

If the line keys flash red in sequence after flashing amber, do not power down the phone until the
Caution
sequence of red flashes completes. This sequence can take several minutes to complete.

4.

These buttons flash on and off in sequence:
Headset (only if the handset is off-hook when the phone powers up. Hang up the handset within
–
3 seconds to have the phone launch its secondary load. To continue with the primary load, leave
the handset off-hook.)

Some or all of the line keys flash amber in sequence.
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.
–
The phone screen displays the Cisco Systems, Inc., logo screen.
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 starts up again and repeats step 1 through step 4 above.
