Optional USB Devices
You can connect a standard USB device (for example, a mouse, keyboard, or both) to
the endpoint using a standard USB cable (not included). Connect the device to the
USB host port located on the back of the endpoint (see
page 3 ). The operating system
automatically detects the device when the endpoint is powered on.
To connect a keyboard: Configure the keyboard properties under Start - Settings -
Control Panel -
Keyboard.
To connect a mouse: Configure the mouse properties under Start - Settings - Control
Panel -
Mouse.
To connect a mouse and a keyboard: Use two USB cables. First connect the mouse
to the keyboard, then connect the keyboard to the USB host port on the endpoint. The
operating system recognizes all interconnected (daisy chained) USB devices.
Power Requirements
The endpoint receives power from an individual power supply unit and should remain
powered on at all times. It is important to use a power supply unit that is compatible
with the endpoint, such as the Inter-Tel Universal Power Supply (part number
806.1119).
Inter-Tel recommends that you plug the endpoint power supply unit into an uninter-
ruptible power supply (UPS). If the power supply unit is not plugged into a UPS and
the power fails, the current call is dropped.
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 or to order a new power supply unit.
Your system may be configured to use a centralized power source (Power over
Ethernet, or PoE) as a backup power source. If your power supply unit fails and
your system is running PoE, you will be able to use the audio portion of the
endpoint only; you will not be able to dial a number (including emergency
numbers), because PoE does not support the display portion of the endpoint.
