Has anyone else had such bad experiences with switches?
I have had 3 different devices fail. First, a 5-port Dlink DSS-5+
(10/100) seemed to lose one of it's ports (a year-or-two ago).
Then another 5-port 10/100, this one a Hawking, actually fried itself.
A couple weeks later, a Dlink DSS-8+ started losing it's memory (I
think). It works for a while upon power up, but then fails to connect
(eg, a ping) in from one port out to another.
I'm even wondering whether the second burn-up may have put overvoltages
on the line and damaged the other -- can that happen?
Am I'm buying too low on the cheap scale?
I've found that often as not problems with the cheap switches turn out
to be the power supply, and have fixed a few of them. One measure is how
hot they get after running for a while. I figure it's not going to last
as long if you can't comfortably hold your hand on the outside of the
case, vs. one with little detectable temperature rise.
The bigger (>=24-port) ones usually have fans and they're often quite
loud, not what I'd want at home but they do seem to last. We have a few
3com 3300-series at work that just keep going. And just today I tossed a
24-port Bay Networks (Netgear) switch onto the bonepile becuase it would
lock up about once a day.
I doubt that one switch's dying could have caused another one to have
problems.
