C About PoE (Power over Ethernet) This appendix provides an overview of Power over Ethernet Technology and how it is implemented in relation to the 7G4285‐49 and 7G4205‐72 DFE modules. Overview Power over Ethernet (PoE) refers to the ability to provide operational power through the same Ethernet cabling to a PD (powered device) connected to a data network. Modern Ethernet implementations employ differential signals over twisted pair cables.
Overview Proprietary PD Detection The 7G4285‐49 and 7G4205‐72 support a subset of the currently deployed proprietary PoE methods. This includes support for Cisco PDs, including a proprietary capacitor based detection scheme. Power Interface The 7G4285‐49 and 7G4205‐72 can interface with an external 48V power supply that resides in a Matrix N5 chassis or from a separate Matrix N‐POE Power System.
Overview PoE Port Status LEDs The PoE port status of each 10/100/1000 Mbps front‐panel port is indicated by the two‐color RX and TX LED display for each port. To observe the PoE port status indications, you must switch the DFE module management system from the default RX/ TX Status Mode to the PoE Port Status Mode using the DFE module front‐panel GROUP SELECT switch. The switch operation and a description of how to use the LED indications are described in “Using LANVIEW” on page 4‐1.
