Connecting a 3Com
Attendant Console
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
“Using Auto Discover for Initial System
Configuration”
on
page 91
.
To connect a 3Com Attendant Console:
1
Connect the power source to the Attendant Console.
For information about connecting power to an Attendant Console, see
the packing sheet that ships with the device or
“Connecting Power to the
Attendant Console”
on
page 113
.
2
Connect the Attendant Console to the LAN switch port located on the
underside of the 3Com telephone.
You can also connect the Attendant Console to the LAN. It does not need
to be connected directly to a telephone.
Power over
Ethernet
(IEEE 802.3af)
power source
3C10400
Connect the powered Ethernet cable directly to the telephone’s Ethernet
connector. No separate power connection is required.
3C10120B
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.

3C10120B
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.
CAUTION:
You can damage an NBX device by using an NBX power splitter (3C10223) with the 3Com Network
Jack Power over Ethernet Multiport Midspan Solution (3CNJPSE24). Use the NBX power splitter (3C10223) only
with the 3Com Ethernet Power Source (3C10220, 12-port, or 3C10222, 24-port).
