The following diagram displays an overview of the recommended installation,
where the IntelliJack is being connected to an Ethernet network cable that is
terminated with a female RJ-45 connector. Detailed installation instructions are
included in the sections that follow.
Power to the IntelliJack can be supplied one of the following ways:
• Over the network via an integrated switch that supports Power Over Ethernet.
• Over the network via a multi-port Ethernet power supply.
• Over the network via a single-port Ethernet power supply.
• Locally via a 3Com local power supply.
Before you begin the installation, determine which type of power supply the
IntelliJack will use.
NOTE: For a list of power supplies that support the IntelliJack, go to
www.3com.com/.
CAUTION: Use only a power supply that is provided or approved by 3Com for
use with this IntelliJack. Failure to do so may result in damage to the IntelliJack,
or may result in a hazardous situation or personal injury.
Using an Integrated Switch with Power Over Ethernet
To use Power Over Ethernet, you must have a switch on the network that has
Power Over Ethernet integrated into it. You must then determine if it is
compatible with IEEE 802.3af.
Using a Multi-port Ethernet Power Supply
To use a multi-port Ethernet power supply, you must connect the power supply to
your network, as shown in the illustration.
