Power Requirements
The endpoint requires either an individual power supply unit or a centralized power
source. The following individual power supply units are compatible with the end-
point:
•
Inter-Tel power supply unit (48-volt DC output)—part number 806.1114
(806.1117 in Europe)
•
Red Hawk Single Port PowerSense
™
(part number 901.0407)
•
An industry-standard IEEE 802.3af power supply unit
If your endpoint uses a centralized power over ethernet (PoE) source, DO NOT use an
individual power supply unit. If necessary, contact your system administrator for
assistance before connecting your endpoint to the centralized power source.
Make sure the endpoint is plugged into an uninterruptible power supply (UPS). If the
endpoint is not plugged into a UPS and the power fails, the current call is dropped and
the endpoint will not be usable until the power is restored.
Software and Firmware
The Model 8662 comes with preinstalled Inter-Tel software and firmware, but occa-
sional software updates may be required when new versions are available. The end-
point is configured to download the updates automatically.
During the download process, several messages display on the LCD and the feature
button lamps illuminate. The download is complete and the endpoint is ready for use
when your user information appears.
CAUTION
Endpoint Damage Hazard.
Make sure your endpoint is connected to the proper
power supply before using.
Contact your system administrator if you have any
questions regarding power requirements
.
CAUTION
Endpoint Damage Hazard.
Do not use your endpoint or disconnect it from the
