to assign specific telephones to individuals and place the telephones in
the correct locations.
You can also use the Auto Discover feature to add single telephones
or small numbers of telephones at a later time (for example, when the
customer wants to add telephones for recently hired people).

configure telephones manually, using the NBX NetSet utility. However,
if you have many telephones to configure, manual configuration can
be a tedious and error-prone process.
Typically, you would add a telephone manually only if you wanted to
configure a particular feature at the same time. For example, you
might want to configure the telephone so that it would not receive
paging broadcasts. However, you can Auto Discover a telephone and
later modify it to configure the features. For information about adding
telephones manually, see the NBX Administrator's Guide.
For either method of adding a telephone, you must either connect the
telephone to the network segment on which the Call Processor resides. If
you use the Auto Discover, you must enable the Auto Discover
Telephones check box before you connect the telephone. If you add a
telephone manually, it does not matter whether you connect the
telephone before or after you use the NBX NetSet utility to add it.
Connecting Power to the Telephone
Connect the AC power converter provided with the telephone to the
power connection on the underside of the telephone and then connect
the other end of the power converter to an AC power outlet. On all NBX
devices, the power connector is labeled with the DC power symbol:
Using a Powered Ethernet Cable to Power the Telephone
To eliminate the power converter, you can connect your 3Com Telephone
to a powered Ethernet cable. NBX devices can use Ethernet power
directly or through the use of one of two types of splitter devices. The
method you use to connect an NBX device to a powered Ethernet cable
depends on the type of Ethernet power in use at your facility and the type
of NBX device you are connecting. On all NBX devices, the Ethernet
connector is labeled with this symbol:
