Connection Details
Connect the AC adapter's power jack to the
the bottom of the phone.
A strain relief tab is molded into the bottom of 1102, 2102, and
2101 phones. A strain relief clamp is molded into the adjustable
stand on 3100-series devices.
If you need an AC adapter, order the optional power adapter
3C10444-XX, where XX is the country code:
AA (Australia/New Zealand)
CN (China)
ME (Europe/LAT)
NOTE: If you use a power brick on a 3103 Manager's Telephone, you
must use the 3C10444-XX power brick. All other 3Com devices can
use either 3C10444-XX or the older power brick, 3C10224-XX.
The part number appears in the label on the bottom of the
telephone.
Connect the powered Ethernet cable directly to the telephone's
Ethernet connector.
All 3Com telephones identify the Ethernet connection with this icon:
No separate power connection is required. However, if you connect
both an AC adapter and a powered Ethernet cable, the device uses
the power from the AC adapter and switches automatically to
Ethernet power if you remove the adapter.
