Installing Mitel IP Endpoints
For complete programming procedures for features introduced with v2.4, refer to the
Programming chapter in the
Inter-Tel 5000 Features and Programming Guide (part no:
580.8006). Refer to other locations in this chapter for information to install or upgrade system
software beyond what is covered in this document.
Connect the cables to your endpoint after you have attached the mounting base unit to it.
Before installing the endpoint, make sure you are familiar with the following powering options:
•
An IEEE 802.3af LAN-powered jack provides power to the endpoint using a LAN cable.
The endpoint receives ethernet signals and power through the same cable, also known as
Power over Ethernet (PoE).
•
An Ethernet power adapter provides power to the endpoint using a LAN cable. The
Ethernet power adapter is connected to the LAN using a separate LAN cable connected to
a jack. (The endpoint receives ethernet signals and power through the same cable.)
To continue to the installation procedure, see page 5-156 .

NOTICES
•
Possible Functionality Degradation . Inter-Tel strongly recommends using the IP
devices on a managed private network. If connected to the public Internet, IP devices
will function, but the quality may suffer due to the dynamic bandwidth availability. The
possible problems could be voice quality degradation, garbled speech, dropped calls,
equipment resets, etc. Also, the VoIP suitability of any Internet connection can change
at any time, with no advance notice.
Inter-Tel cannot guarantee any voice quality
when connected to the public Internet. Therefore, Inter-Tel is not responsible for
network quality issues that are caused by using the public Internet.
For
recommended guidelines on IP network specifications, refer to the main installation
manual.
•
Possible Network Instability . Do not connect the IP endpoint PC ports to each other,
and do not connect them to a hub. Doing so may cause adverse network conditions.
Also, Inter-Tel recommends that you not connect additional hard IP endpoints to the PC
ports. Due to the QoS (Quality of Service) of the hard IP endpoints, those located
downstream will have a lower priority when sending data to the network. Under heavy
network conditions, voice quality may be diminished.
•
Equipment Damage Hazard . Only use a single appropriate power adapter with the IP
device. Do not connect a U.S. power supply and a Universal power supply to the same
IP device. Also, when using the Universal Power Supply with a barrel connector, no
devices, such as hubs, should be inserted between the KS/SLA jack on the adapter and
the LAN jack on the IP endpoint because power is supplied through the cable.
To reduce the effects of AC voltage surges and spikes that may cause damage to the
electronic components, a surge/spike protector with the following specifications is
recommended:
o
Clamp voltage transients at 300 VAC within 5 nsec when exposed to waveforms as
described in the ANSI/IEEE Standard C62.41-1980 (IEEE 587).
o
RFI/EMI noise reduction by at least 20 dB at frequencies between 5 kHz and 30
MHz.
The Inter-Tel CommSource division sells a surge/spike protector, part no. 900.0500, that
possesses all of the recommended specifications.
