The 3Com Ethernet power sources (EPS) let companies with NBX telephones or 3Com wireless access points connect and power these devices from a single location using their LAN cabling. With the EPS located in a secure wiring closet or other central location, you can easily access and manage the distribution of power to devices throughout your organization. EPS eliminates the need for a local power outlet and power cable for each device. One wire provides both 10/100BASE-T connectivity and power, freeing power outlets for other electronic equipment.
