Boot-Up Light Sequence; Factory Reset - Plantronics IP40 Administration Manual

The port labeled with the network icon (right hand port) can be used to power the device
from an 802.3af provisioned network connection. The IP40 is a Class 1 PoE device

2.6 Boot-up Light Sequence

During boot-up, the Answer/End light will blink yellow until it has an IP address and has
initialized its signaling stack.
Once the yellow power light stops blinking, the adapter will either be ready to use (no
control button lights) or the adapter will be in an error state. If there is an error state, the
Answer/End button will be solid red. Briefly pressing the Answer/End button during an
error state will play the specific error message (see section 10 Debugging and
Troubleshooting for more details).
During a firmware upgrade, the mute button will blink red. Do not interrupt a firmware
upgrade.
A summary of the LED indications can be found in Section 9

2.7 Factory Reset

To restore the IP40 to factory configuration settings, hold down the Volume Up and
Answer/End buttons while powering on the IP40. The mute LED and Answer/End LED
will blink red for several seconds. When the LEDs become solid RED, release the
buttons. The IP40 will then reboot with factory configuration settings.
