Basically we had a power cut in the office yesterday and since then one of our switches
Doesn’t work. We have two, both GS748T. One came back up, first just on a few ports
Then all ports came back up. The other one came up with a few ports working but they
We’re passing any traffic. I unplugged this switch again and when I power it on, although the
Power indicator light comes on no port lights come on. I can also no access it via the web interface
And the smartwizare cannot discover it on our newwork.

Sounds like that one might have gotten damaged. I'd probably check with Netgear to see if they have any recommendations for a way to reset the switch, etc.

Yeah, I have logged a call with Netgear, am waiting to hear back, just thought I'd ask here in the mean time.

Any chance the switch is under warranty? You might be able to work that angle with them.

OK, so this issue looks to be solved.  I turned the switch off for 1 hours, plugged it back in and it worked right away.

I was going to suggest that, because I've done it before, but I don't entirely understand why it works, and I didn't really want to post it as a solution in case you actually do have a problem and need to warranty it. I have had some equipment that wouldn't work until I left it unplugged for several hours or even days and then it came back on. Glad to hear you got it working though.

Well my device was under warranty and they said they'd replace it but no need now.
