 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.
