Have you tried the serial interface? You wouldn't have to reboot to connect to it and see what's going on with the switch.
Hello all! I was hoping someone could tell me what is going on with my switch.  I have a powerconnect 6224 and it is hooked up and been running fine for almost 1 year.  The switch is located at our NOC.  All but 3 of the ports are being used.  Occasionally, When I'm at the NOC, I need to get in, I connect my laptop up to one of the three open ports to connect to the network.  That has been working fine.  All of a sudden, I came to the NOC and now NONE of the three open ports will work.  no green lights and I have set my IP to an IP on the domain (manually, as usual), I can't even switch one out of a good port to one of the three that are not working.  Question:  Can I reboot the switch without it 'failing'?  I know that I had problems with the dell powerconnect 2724 switch when I pulled the power from it and then tried to rehookup power.  I'm afraid to cut the power and 'reboot' the switch.  Any ideas why this would happen or if I can safely reboot?  Oh....I can't get into the web interface either....I've tried from a local computer as well that is hooked up to the same subnet, but no luck....I can't even get the IP that the switch "should be" to ping back.
