[rescue] Gigabit Ethernet SBus & Gigabit Ethernet Sun 420R/220Ryi

[Nick B.]

One thing to keep in mind, the 1000baseT gbics pull alot more power than the
1000baseSX (don't ask me why, I'm not sure either, but I know they do, and on
the line cards they are supported in there is a limit to how many you can run)
