Proprietary PD Detection

Proprietary PD Detection

The 4H4285‐49 supports 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 4H4285‐49 can interface to an external 48 Vdc supply that resides in a Matrix N5 chassis or from a separate Matrix N Series N‐POE Power System.

Matrix N5 Backplane 48 Vdc Interface

The 4H4285‐49 has a connector that interfaces with the backplane of the N5 chassis for 48 Vdc power. This power connection on the 4H4285‐49 is fused, has EMI suppression components for this interface, and can support a sustained output current of 20 A.

Front Panel 48 Vdc Interface

The 48 Vdc Optional Power Input connector on the 4H4285‐49 front panel provides a power interface connection for an Enterasys Matrix N Series N‐POE Power System, which provides the 48 Vdc power and return as well as the power supply status signals. The status signals indicate the presence and operating state of each power supply module in the N‐POE Power System. This 48 Vdc Optional Power Input interface is not fused as the N‐PoE Power System has a circuit breaker for each PoE switch module power feed.

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.
