[rescue] SBUS Efficient Networks Inc fiber network adapter on a Sparcstation 4

[Doug McIntyre]

If its 155Mbps, thats an ATM card.
So you'd need to have an ATM switch, ATM optics, the proper ATM drivers, etc.
It won't interop with Ethernet.

Back from a time when people (mostly the telcos) believed ATM to the
desktop was a viable alternative to Ethernet.

(Also; why is it 155 Mbps, and would this play nicely with a 100 Mbps switch?).
