Ethernet switch locks and all speed lights blink simultaneously
Posted on 2006-04-12
Ethernet switch locks and all speed lights blink simultaneously. Everything runs 100mbits. I need to power down the switch and everything comes back. So far I have replaced the switch. Also found an intermitently bad cable between patch panel and switch. There were 6 hand made cables and since one was bad, I replaced all of then with factory cables. During this process it went down at least a half dozen times. It then worked for 4 hours and locked up again. I had the client power the router/dsl modem and switch and the network and internet would come right back.
This all started yesterday when there was a power failure in the neighborhood. Thou it might be unrelated, the phone system started to do goofy things like not answer and transfer to the wrong phone. The phone, switch and router share the same power outlet on the wall but have different power strips. I was suspecting some sort of power issue and will put the router and switch on a UPS. (should have been done originally by the original installers!!!!)
