4) 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 Ethernet power supply, you
must purchase a local power supply from 3Com. To use the local
power supply, make sure you have an electrical outlet near the site
where the NJ90 will be installed.
