Installing the Ethernet cable

The SmartNode 4520 Series has automatic MDX (auto-cross-over) detection and configuration on the Ether- net ports. Any of the two ports can be connected to a host or hub/switch with a straight-through wired cable (see figure 17). Ethernet devices (10Base-T or 100Base-T) are connected to the SmartNode’s Ethernet ports (see table 8 for port pin-out listing) via a cable terminated with RJ-45 plugs. A cross-over cable is only required when connecting SmartNode 4110 Series devices to a host (see figure 18 on page 39).
