The four ports PoE midspan provides up to 15.4 Watts of power over Ethernet and offers a IEEE 802.3af-compliant solution to upgrade existing infrastructures with PoE, providing a maximum of 15.4 watts of power through each port and ensuring safe operation of any standard PoE data terminal. The PD-3504G provides PoE to IP telephones, wireless LAN access points, security network cameras and IP terminals to receive power, along with data, over standard Ethernet cables, leaving network infrastructure completely unaltered. With the midspan's plug-and-play installation,it can be easily and cost-effectively implemented leveraging an existing Ethernet infrastructure while at the same time providing the assurance of a future-proof network.
