FINDING YOUR WAY
Message Indicator Lamp
The Message Indicator lamp (located at the top, right corner of the endpoint) shows
the same indications as the button. The Message Indicator lamp flashes when-
ever there is a waiting message.
NOTE: By default, the message lamp is programmed to light when you receive a new
voice mail message. However, this lamp can be programmed for other functions. Check
with your system administrator if you are unsure what your endpoint’s lamp is pro-
grammed to indicate.
Power Requirements
The Model 8662 requires either an individual power supply unit or a centralized
power source to power the endpoint. Check with your system administrator about the
specific power requirements for your endpoint.
Before connecting a power supply unit, make sure it is compatible with your end-
point. The following individual power supply units are compatible with the Model
8662:
Inter-Tel Power Supply Unit (Part Number 806.1114/806.1117 in Europe)
Red Hawk Single Port PowerSense (Part Number 901.0407)
An industry-standard IEEE 802.3 Power Supply Unit
It is recommended that you plug your endpoint’s individual power supply unit into an
Uninterruptible Power Supply (UPS). If your endpoint’s power supply unit is not
plugged into a UPS and the power fails, the current telephone 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) rather than an individual power supply unit. Your system administrator will
explain how to connect your endpoint to the centralized power source. If your end-
point uses power over Ethernet, do not connect an individual power supply unit to the
endpoint.
