SmartNode 2290 Series Quick Start Guide 5
1.4 Installing the Ethernet cable
The SmartNode 2292 Series has automatic MDX (auto-cross-over) detection and configuration on the Ethernet
ports. Any of the two ports can be connected to a host or hub/switch with a straight-through wired cable (see
figure 5 ). Ethernet devices (10Base-T or 100Base-T) are connected to the SmartNode’s Ethernet ports (see
table 2 for port pin-out listing) via a cable terminated with RJ-45 plugs. Because the SmartNode 2294 Series
does not have the MDX feature, a cross-over cable is required when connecting SmartNode 2294 Series devices
to a host (see
figure 6 ).
Note Pins not listed are not used.
