Reset Button; Power Requirements - Inter-Tel 8690 User Manual

Reset Button

If your endpoint is equipped with a reset button on the back, pressing it immediately
shuts down the operating system and any applications that are currently running on
the endpoint, the screen goes blank, and the default settings are restored. After a few
moments the operating system restarts and the client application re-opens when net-
work connectivity is re-established.
Do not press the Reset button on your endpoint unless you are told to do so by
your system or network administrator. Desktop shortcuts and any preferences
that have not been saved in the registry are lost when you press the Reset button. In
addition, the endpoint will require additional programming to restore it to its previ-
ous operational state.

Power Requirements

The Model 8690 should remain powered on at all times. The endpoint receives power
from an individual power supply unit. It is important to use a power supply unit that is
compatible with the endpoint. The Inter-Tel Universal Power Supply (part number
806.1119) is compatible with the Model 8690 endpoint and is available through Inter-
Tel's CommSource
It is recommended that you plug your endpoint's power supply unit into an Uninter-
ruptible Power Supply (UPS). If your endpoint's power supply unit is not plugged
into a UPS and the power fails, the current call will be dropped.
NOTE:
Contact your network administrator to order a new power supply unit for your
endpoint.
Your system may be configured to use a centralized power source (power over Ether-
net) as a backup power source. Your network administrator will explain how to con-
nect your endpoint to the centralized power source. If your power supply unit fails
and your system is running power over Ethernet, you will be able to use the audio
portion only of the endpoint. Power over Ethernet does not support the display portion
of the endpoint.
