Connect the powered Ethernet cable directly to the telephone's Ethernet
connector. No separate power connection is required.
Devices that predate the 802.3af standard can be
powered by an 802.3af-compliant power supply with
the use of the 3Com Network Jack to NBX Phone
Power Module (3CNJVOIPMOD-NBX), which is
802.3af-compliant. The module removes power from a
powered Ethernet cable and splits it into a power jack
and an unpowered Ethernet connection that you
connect to the ATA's LAN port and power connection.
The 3Com Ethernet Power Source predates the 802.3af standard.
Any NBX device can be powered by a 3Com Ethernet Power
Source if you use and NBX Power Splitter (3C10223 – package of
12). The NBX Power Splitter removes power from a powered
Ethernet cable and splits it into a power jack and an unpowered
Ethernet connection that you connect to the ATA's LAN port and
power connection.
The optional 3Com Attendant Console provides attendant (receptionist)
access and monitoring for up to 100 extensions per console.
Do not Auto Discover the Attendant Console before you have Auto
Discovered telephones and Analog Line Cards. For more information
about Auto Discover, see
