    3Com 3824 problem

    We've just acquired a 3Com 3824 24 port gigabit switch which we want to use to replace our existing 10/100 core switch.

    According to the documentation it should pick up an IP from the DHCP within 2 minutes of being turned on and from then can be configured by web interface but should also work straight out of the box.

    When I turn it on all I get is one light to say that power is connected. If you look in the DHCP it isn't picking up an IP (since the MAC address isn't listed) and even though I have servers and switches plugged in to it all the port lights are out.

    Does anyone have any ideas?

    PS. Am going to try serial link but this shouldn't be happening ... should it?

    Did you buy this new or were you given it from someone else?

    Re: 3Com 3824 problem

    Is there a method of performing a factory re-set externally?

    Sounds like the factory did a bad flash of the firmware to me. Like I said, its broken.

    You can sometimes reflash them by serial cable in a kind of 'emergency' mode. Check the docs to see if it supports this (I know our 3coms do here for example).
