Front Panel 48 Vdc Interface

The 48 Vdc Optional Power Input connector on the 4G4285‐49 front panel provides a
power interface connection for an Enterasys Matrix N‐POE Power System, which
provides the 48 Vdc, 20 Amperes of power and return as well as the power supply status
signals. The status signals indicate the presence and operating state of each Matrix N‐POE
Power System power supplies. 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.

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.
Table C‐2 provides a brief description of each port status RX/TX LED display.
