The device is labeled as follows:

SuperStack II
Netbuilder 200
espl-310
3c8200c

We have several of these bridges, one of them has quit working. It is
flashing lights in a steady pattern.

I have been scouring the web for information and hoping to find a
flash utility to flash the firmware-which has worked for me in the
past on other brands of bridges. 3coms site has almost no mention at
all of this product.

ANY tips greatly appreciated. If we can't make this thing work it
will cost lots of money to come up with an alternative.

Thanks,
