Switch Failure

By taylorjes ·
I run a small office network for my dads
company; nothing too complicated. MS Win Server
2003 SBE, 10 Xp Pro SP3, and a few other
things. My current problem is that I'm at
school and the network is 6 hours away. The
office called today to tell me that they had a
'network cable disconnect' error upon login and
they have no shared
resources/internet/Exchange. I've gone through
some basic restart and pray and now I've
isolated the switch as the issue.

My Question is what are the failure rates of a
switch; should I be concern as to the
environment for future problems? What a
reliable replacement? General advice?

All hardware has failure potential

by LarryD4 In reply to Switch Failure

All hardware can fail, reliability usually depends on the brand. I had a switch go bad once and that was a 3Com and it was in continuous operation for five years.

I know its a small network, but I usually try to stick to name brands.

This could just be your one time though.

Be sure its on a surge and/or a UPS, I have seen other switches(not managed by me) go bad becasue of power spikes on the power provided from the wall.

The more expensive the switch

by Dumphrey In reply to Switch Failure

the better quality components it should contain, and thus lower failure rates. But any port can go bad. The real question is how expensive is it if a port goes out on you. Is it cheeper to buy a $2000 switch and have a better margin of hw failure, or a $50 switch and replace it as needed?
(Cost needs to include loss of productivity and possible loss of business).

A hot-spare switch on the shelf beats a six-hour drive any day

by robo_dev In reply to Switch Failure

Switch failures, if it's a brand name product are rare.

Most failures I've seen are either power surge/lightning related, or due to el-cheapo wall-wart power supplies like you find in the cheap consumer-grade products.

When you pay $$$ for a switch, you get a quality power supply, and the best ones have multiple, hot-swappable power supplies.

For the time/cost of a six-hour drive, either buy one enterprise-class switch (Cisco) with dual power supplies or a couple of extra of those $39.95 consumer-grade switches to serve as hot spares, and leave them there on the shelf. ( be sure to test those cheap ones first!)

Oh yeah!

Even if its a cheezy old one, you should have something in place for a failure.

Switch Rates

by Ekline In reply to Switch Failure

It depends on the make and model of the switch. Yes, Switches do have a "life" before they must be restarted. Wouldn't be able to tell you off the top of my head.

If your cold boot doesn't work and everything else seems to be normal but the switch. Then I would replace it to test its operability

Thanks

by taylorjes In reply to Switch Rates

So I was forced to have a friend replace the
switch for me; now when I get back I'll test
the switch and see what the problem was. I
was able to check my UPS and there was a
power surge that night, however the switch is
connected to a UPS (not that one), so maybe
the UPS failed too. I have some work ahead,
but thanks for the help.

Last question: The switch (failed) and new
switch are both Linksys (~$60; is that a safe
choice for my situation. I've never had a
problem with any of their products in the
past, but this is the 'largest' network I've
had responsibility over. Thanks again

Linksys=good bet

by LarryD4 In reply to Thanks

I have been using them for a while and have been pretty happy with them. We use Cisco on the large scale and for small needs we buy the Linksys 4 or 5 porters as needed.
