You may run into problems if the transceiver is generating heartbeat, which the Suns (using 802.3) don't want. Also, I'm not sure how configurable the on-board ie is, but you might want to check whether it's set for the right level of Ethernet. I know this has to be done for the second Ethernet interface, by means of a jumper (level 1.0 vs. 2.0). Other than that, I'd say "start screaming". If you don't have the cable plugged in, your Sun 4 should be saying "ie0: no carrier", not "jammed". -- Ruth Milner UUCP - {uunet,pyramid}!utai!helios.physics!sysruth Systems Manager BITNET - sysruth@utorphys U. of Toronto INTERNET - sysruth@helios.physics.utoronto.ca Physics/Astronomy/CITA Computing Consortium
