Connecting 48 Vdc Power for PoE Operation

Connecting 48 Vdc Power for PoE Operation

The Matrix N7 (7C105‐P) chassis provides 48 Vdc to connected PDs (powered devices) by way of its backplane connection to a PoE‐compliant DFE module such as the 7G4285‐49 or 7G4205‐72.

For a Matrix E7, (6C107), Matrix N3 (7C103) and Matrix N7 (7C107) chassis, an optional external Enterasys Matrix N‐POE Power System is required to support PD connections to the 7G4285‐49. The power from the Matrix N‐POE Power System is supplied through a DC power cable connection to the front‐panel 48 Vdc Optional Power connector on the 7G4285‐49.

Warning: The 48 V wire harness contains two fuses, F11 and F29. If a fuse needs to be replaced, it must be done by service personnel only. The fuse must be replaced with the same Type and Rated fuse 20 A, 400 VDC.

Advertencia: E arnes del cable de 48V contiene dos fusibles, F11 y F29. Si un fusible requiere ser reemplazado, debe ser hecho por personal de servicio unicamente. El fusible debe ser reemplazado por uno del mismo tipo y clasificado como fusible de 20 A,

400 VDC.

Warnhinweis: Im Kabelbaum der 48V Zuleitung befinden sich 2 Sicherungen, F11 und F29. Die Sicherung darf nur duch Fachpersonal getauscht werden und darf auch nur durch den gleichen Typ ersetzt werden ( 20A / 400VDC ).

Note: If you are planning to install a PoE-compliant DFE module such as the 7G4285-49 in a Matrix N3 (7C103) or Matrix N7 (7C107) chassis, install and connect the Matrix N-POE Power System before connecting to PDs.

Refer to the Matrix N‐Series N‐POE Power System Installation Guide to install and connect a Matrix N‐POE Power System to the 7G4285‐49.

Connecting to the Network

This section provides the procedures for connecting unshielded twisted pair (UTP) segments from the network or other devices to the 7G4285‐49 and 7G4205‐72 (“Connecting UTP Cables to DFE Modules” on page 3‐13).

Note: If the module is being installed in a network using Link Aggregation, there are rules concerning the network cable and port configurations that must be followed for Link Aggregation to operate properly. Before connecting the cables, refer to the Enterasys Matrix DFE-Platinum Series Configuration Guide for the configuration information. For details on how to obtain manuals, refer to the “Related Documents” in About This Guide.
