Connecting to the Network

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.

This section provides the procedures for connecting unshielded twisted pair (UTP) segments from the network or other devices to the 4G4285‐49 and 4G4205‐72 (“Connecting UTP Cables to DFE Modules” on page 3‐14).

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-Gold Series Configuration Guide for the configuration information. For details on how to obtain manuals, refer to the “Related Documents” in About This Guide.

Connecting UTP Cables to DFE Modules

The fixed RJ45 front panel connections of the 4G4285‐49 and 4G4205‐72 are 10/100/ 1000 Mbps ports. These ports have internal crossovers, and support automatic‐polarity sensing when configured for automatic‐negotiation.

If automatic‐negotiation is not activated on a port, use a straight‐through cable when connecting a workstation to the port. When connecting a networking device to the port, such as a bridge, repeater, or router, use a crossover cable.

If a port is set for auto‐negotiation, automatic‐polarity sensing is also activated. Automatic‐polarity sensing eliminates the need for a crossover cable, regardless if the connection is to another network device or a workstation.

Note: All RJ45 front panel ports on these DFE module support Category 5 Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. Category 3 cable may be used if the connection is going to be used only for 10 Mbps.
