The DEC H4000 transceiver is documented to draw over 20 amps when
first starting up. That's amps, not milliamps. What's worse is that
this is from the +12V supply which doesn't have nearly as much
capacity as the +5V supply.

I just started using the Cabletron transceiver (well, actually, it's a
MAU) with LANView and am very happy with it.
