Enterasys Networks 4H4285-49, 6H308-48, 9033989-06 manual

Connecting 48 Vdc Power for PoE Operation

The Matrix N5 (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 4H4285‐49.

Note: When you install the 4H4285-49 in a Matrix N5 chassis, the 4H4285-49 48 Vdc Optional Power Input does not support a connection from an external N-POE Power System. The 48 Vdc power is supplied through the backplane of the N5 chassis from its own 48 Vdc power modules. If none of these power modules are installed, then there is no PoE support.

Warning: The DFE module is shipped with a cover over its 48 Vdc Optional Power Input connector. Do not remove this cover when the DFE module is installed in an N5 chassis. This cover is removed only when you connect a 48 Vdc power cable from the Enterasys N-POE Power System.

Advertencia: El modulo DFE es embarcado con una cubierta sobre su conector de poder opcional de 48 Vdc. No remover esta cubierta cuando el modulo DFE es instalado en un chassis N5. Esta cubierta debe removerse unicamente cuando se conecta el cable de poder de 48 Vdc hacia el Sistema de Enterasys de Energia por Cable (Enterasys N-POE Power System).

Warnhinweis: Im Auslieferungszustand der DFE Module stülpt eine Schutzkappe über dem 48V Gleichspannungs-Anschluss, die nur dann abgezogen werden darf, wenn ein Enterasys N-POE Power System angeschlossen wird. Keinesfalls darf diese Schutzkappe abgezogen werden, wenn das DFE Modul in einem N5 Chassis installiert wird.

For 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 4H4285‐49. 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 4H4285‐49.

Warning: The 48V 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 4H4285-49 in a Matrix E7 (6C107), 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 4H4285‐49.
