Using the 3Com Local Power Supply

If your network does not support Power Over Ethernet, or if you
are not using a single-port or multi-port endspan power supply,
you must purchase a local power supply from 3Com. See
Appendix B "Obtaining Optional Components".
To power the IntelliJack with a local power supply, make sure
you have an electrical outlet near the site where the IntelliJack
will be installed.
