6. Trouble shooting
Make sure you are using the correct DC power suppliers (DC12 to 48
V). Do not use power suppliers with DC output over 48V. It may
damage devices.
Select Ethernet cables 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 are 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 go 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.
