Unit must not connect directly to telecom network voltage (TNV).
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 20
on page 38). Ethernet devices (10Base-T or 100Base-T) are connected to the SmartNode's Ether-
net ports (see
table 7
for port pin-out listing) via a cable terminated with RJ-45 plugs. Because the SmartNode
4110 Series does not have the MDX feature, a cross-over cable is required when connecting SmartNode 4110
Series devices to a host (see

Pins not listed are not used.
