Installing Nortel Ip Telephones; Before Installing - Nortel BCM50 Configuration Manual

Installing Nortel IP telephones

A maximum of 90 IP telephones, including Nortel Networks 2050 IP Software Phones, and H.323
devices, can be connected on the BCM50, if the system resources support the deployment.
The Nortel Networks IP telephones (20XX) can be registered to the network by the end user or by
the administrator. If the end user is configuring the telephone, the administrator must provide the
user with the required parameters.

Before installing

Before installing 20XX IP telephones, ensure that:
• the telephone has the appropriate power supply for your region
• if powered locally, the installation site has a nearby power outlet;
otherwise, it can be powered through a Power Inline Patch Panel (PiPP)
• the installation site has a 10/100 BaseT Ethernet connection
Caution: Do not plug the telephone into an ISDN connection. This can cause severe
damage to the telephone. Plug the telephone only into a 10/100 BaseT Ethernet
connection.
• if you are using an IP telephone that does not have a 3-port switch, ensure you have 10/100
BaseT Ethernet connections for both the telephone and for your computer equipment.
Using a 3-port switch
In an office environment where a LAN network already exists, most computers will already be
connected to a LAN line. To avoid the necessity of installing duplicate network connections, you
can use a Nortel Networks 3-port switch for older model 2004 IP telephones. This switch allows
the telephone and computer to connect to the same network connection. For more information,
consult the 2004 setup card and the 3-way switch documentation.
