1. Faulty or loose cables Look for loose or obviously faulty connections If they appear to be OK make sure the connections are snug IF that does not correct the problem try a different cable m Non standard cables Non standard and miss wired cables may cause numerous network collisions and other network problem and can seriously impair network performance A category 5 cable tester is a recommended tool for every 100Base T network installation Improper Network Topologies It is important to make sure that you have a valid network topology Common topology faults include excessive cable length and too many repeaters hubs between end nodes In addition you should make sure that your network topology contains no data path loops Between any two ends nodes there should be only one active cabling path at any time Data path loops will cause broadcast storms that will severely impact your network performance 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 your2.
