Diagnosing LED Indicators                   
 
The Switch can be easily monitored through panel indicators to assist in identifying 
problems, which describes common problems you may encounter and where you can 
find possible solutions. 
 
IF the power indicator does turn on when the power cord is plugged in, you may have a 
problem with power outlet, or power cord. However, if the Switch powers off after 
running for a while 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. 
 
 
Cabling                                   
 
UTP ports  use unshielded twisted-pair (UTP) or shield twisted-pair ( STP ) cable for 
RJ-45 connections: 100Ω  Category 3, 4 or 5 cable for 10Mbps connections or 100Ω 
Category 5 cable for 100Mbps connections. Also be sure that the length of any 
twisted-pair connection does not exceed 100 meters (328 feet). Gigabit port should 
use Cat-5 or cat-5e cable for 1000Mbps connections. The length does not exceed 100
