power adapters. Do not use power adapters with DC output over 48V. It will
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 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 cannot be 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 power cord. Than check for loose power
connections, power losses or surges at power outlet. IF you still cannot
resolve the problem, contact your local dealer for assistance.
