With the R8 processor, there are two issues:
1. Certain RAC cards don't work properly when Vs Msg PC card is in Slot 2. The modem in the RAC card doesn't work, so the system cannot be administered remotely.
2. There is also an issue with Remote Admin when there is a 308 placed in Slot 1 of a 5-slot carrier. The modem is affected and doesn't work.
