124 CHAPTER 3: T ELEPHONES AND ATTENDANT CONSOLESManually ConfigureTelephonesYou can add telephones to the system manually using the NBX NetSetutility. However, if you have many telephones to configure, manualconfiguration can be a tedious and error-prone process. For informationabout adding telephones manually, see the NBX Administrator’s Guide.Manual Configuration Notes■ Typically, you must connect the telephone to the network segment onwhich the NCP resides to enable the NCP to communicate with thetelephone. You can manually define a telephone’s ability tocommunicate with its NCP by using the Telephone Local User Interfaceutility (LUI) or the 3Com Telephone Local Configuration application(TLC). The LUI utility resides on each 3Com telephone. You can installthe TLC application to your PC by clicking Downloads > ApplicationsFor details about these tools, see the NBX Administrator’s Guide.Connecting Power tothe TelephoneAll 3Com telephones can accept power from an AC converter, however,the power converter is an optional component on 3Com 3100-seriestelephones because these devices are compliant with the IEEE 802.3afPower over Ethernet (PoE) standard.To eliminate the power converter, you can connect your 3Com Telephoneto a powered Ethernet cable. NBX devices can use Ethernet powerdirectly or through the use of a splitter device. The method you use toconnect an NBX device to a powered Ethernet cable depends on the typeof Ethernet power in use at your facility and the type of NBX device youare connecting. See Table 28 for power connection details.The base stations for 3Com 3106C and 3107C Cordless Telephones donot support PoE.
