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.
