Fast Ethernet with Power-Over

Key Features:

Fast Ethernet Switches with Power-over-Ethernet

A family fast Ethernet switches with up to 5×10/100Base-TX ports supporting PoE which facilitates the direct supply of terminal devices with power up to 15.4 per port,The extended versions of the switch is also equipped with fiber optic port in multi-mode or single mode version.
• This switch can be operated immediately with no configuration required as ports are set automatically by auto negotiation
• Easy configuration, no extensive configuration
• 4x 10/100TX ports with PoE
• according to IEEE802.3af
• Version with fiber port for multimode and single mode
• 48 VDC power input, redundant
• Potential free contact indicates power loss
• Effective overvoltage protection
