The multi-port Ethernet power supply from 3Com connects to an existing Ethernet
or Fast Ethernet infrastructure with standard Category 5 or Category 5e UTP
cabling, and powers up to 24 IntelliJacks. See “Obtaining Optional Components”
on page 4 for ordering information. For complete installation instructions, see the
multi-port Ethernet power supply documentation.
Using a Single-port Ethernet Power Supply
To use a single-port power supply, connect the power supply to the network hub
or switch and to the IntelliJack, as shown in the following illustration. See
“Obtaining Optional Components” on page 4 for ordering information. For
complete installation instructions, see the single-port Ethernet power supply
documentation.
Using the 3Com Local Power Supply
To use the local power supply, make sure you have an electrical outlet near the
site where the IntelliJack will be installed. First plug the power cord into the
IntelliJack, then plug it into the electrical socket. See page 12 for more details.
