power adapters. Do not use power adapters with DC output over 48V. It will
damage the device.
Select Ethernet cables with specifications suitable for your applications to set
up your system. Ethernet cables are categorized into unshielded twisted-pair
(UTP) and shielded twisted-pair (STP) cables. Category 3, 4, 5 Ethernet
cables are suitable for systems with 10 Mbps transmission speed. For
systems with 100 Mbps transmission speed, Category 5 Ethernet cables are
the only suitable specifications for this environment. You also need to make
sure that the distance between each node is not longer than 100 meters (328
feet).
If the power indicator does not turn on when the power cord is plugged in, you
may have a problem with the power cord. Check for loose power connections,
power loss or surges at the power outlet. If you still cannot resolve the
problem, contact your local dealer for assistance.
