TTENDANT ONSOLES
The 3Com 3105 Attendant Console complies with the IEEE 802.3af
standard, commonly called Power over Ethernet (PoE), so a power
converter is an optional component. To use a power converter, order
power adapter 3C10224-XX, where XX is the country code:
AA (Australia/New Zealand)
■
CN (China)
■
ME (Europe/LAT)
■
SA (South Africa)
■
UK (United Kingdom)
■
US (North America)
■
Using a Powered Ethernet Cable to Power an Attendant Console
To eliminate the power converter, you can connect your Attendant
Console to a powered Ethernet cable. The Attendant Console cannot
accept power directly from an IEEE 802.3af-compliant power source. You
must use a device to remove power from the cable. The device you use to
connect an Attendant Console to a powered Ethernet cable depends on
the type of Ethernet power in use at your facility. NBX devices work with:
Ethernet power sources that comply with the IEEE 802.3af standard
■
3Com Ethernet power sources that predate 802.3af
■
See Table 20 for power connection instructions for 3Com Attendant
Consoles.
