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.
