voltage measured at the power connector is DC10 to 60 V. Do not use
power supplies with DC output over 60V. It may damage the device.
Select Ethernet cable with specifications suitable for your applications
to set up your systems. Ethernet cables are categorized into
unshielded twisted-pair (UTP) and shielded twisted-pair (STP) cables.
Category 3, 4, 5, 6 Ethernet cables are suitable for systems with 10
Mbps transmission speed. For systems with 100 Mbps transmission
speed, Category 5, 6 Ethernet cables provide the only suitable
specifications for this environment. You also need to make sure that
the distance between each node cannot be longer than 100 meters
(328 feet).
If the power LEDs goes off when the power cord is plugged in, a power
failure might occur. Check the power output connection to see if there
is any error at the power source. If you still cannot solve the problem,
contact your local dealer for assistance.
