    Usually a reboot will get the procurve to pick up an address again. On occasion I've had to do a factory reset before it would pick up a dhcp address. Once I've found them I switch it to a static address.

    If reboot doesn't work then you can always telnet in via the serial port and see what it's up to.

    And that serial cable is like gold dust. Can never let it leave my sights as one of my other colleagues would more than likely nick it and then it would be missing when I need it most!

    And when one of those switches has gone potty as the result of the powercut and you've got 30 switches to run round and powercycle before you can even start troubleshooting the problem...

    Its not just recommended practise for the sake of it

    Now few things kicks in when you say powercut!

    Last week we had we had to switch the server off due to the some emergency electrical work going on in the building. By the time the power was back, the switches were back on before the server but i dint notice any of this as the network was running fine.

    But if i remember right, when i restarted teh server, i switched off 2 of the switches and turned them back on as the server was coming back up! And these are the switches that are actually showing up as active on DHCP and i can get to the login console via ip address.

    Now if i am correct, if i restart the other 3 switches after school today, i should be able to see them under DHCP as active?

    Seems like a good bet, yes

    dont think ive got any school with more than 5 switches in and most have 3 at the most almost always in the same rack. I do see your point i just dont like static ips if i can avoid them

    try a factory reset - using 2 pens - hold clear and reset buttons in - release reset and then release clear - i think - check manual

    Do these switches use the 192.168.2.10 address like the Procurve 1810 switch I just installed?

    Factory reset - yes
    Normal reset - no

    However, was the switch configured when it was first installed? Most of the time, nothing apart from the IP settings and some minor configuration (like spanning tree) is done when first installed. As long as you don't have multiple links in between the same set of switches, a factory reset won't do any harm. It'll pick up a new DHCP address as that's the factory default setting.

    I'll check if i have a serial cable tomorrow and the exact type of switch it is!
    We had it setup as it has dual link between some switches so i wouldnt risk a reset.
