Placing the SmartNode device
Install the SmartNode device in a 19-inch rack or place it on a desktop or similar sturdy, flat surface. Allow suf-
ficient space at the rear of the chassis for cable connections. Additionally, you should consider the need to
access the unit for future upgrades and maintenance.
Connecting the 10/100/1000Base-T Gigabit Ethernet LAN and WAN cables
The SmartNode 4740 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.

3.
Verify that the resistance of the ground path is less than 0.5 ohms.
To prevent overheating and damaging the unit, proper ventilation
is required when placing the device; leave at least 2 inches (5
cm) to the left, right, front, and rear of the SmartNode device.
The device should be installed in a dry environment with suffi-
cient space to allow air circulation for cooling. Do not stack multi-
ple SmartNode devices directly on top of one another, and do not
place items on top of the device. If you will be installing equip-
ment above the SmartNode device, leave at least 2 inches (5
cm) of clearance between the devices.
Do not work on the system or connect or disconnect
cables during periods of lightning activity.
The Interconnecting cables shall be acceptable for external
use and shall be rated for the proper application with
respect to voltage, current, anticipated temperature, flam-
mability, and mechanical serviceability.
According to UL60950/IEC62368, a connection to earth
ground—using the grounding stud at the rear of the units
(see
)
—is required to protect against
power cross.
