You don't mention if you've actually programmed the C004. The C004 links are all disconnnected when the B008 powers up. You can easily program the links as required by using a product such as ispy/check (available from the author at http://www.wizzy.com/wizzy/ispy.html) or MMS (Module Motherboard Software, provided with the B008, I think.) There is a latch on the T2 that is used to program the C004 that sometimes prevents a network mapping tool (which I assume "rapy" is) from seeing the C004. The latch can be reset by resetting some internal memory space on the chip, the easiest way being ispy/mtest (see above.) -- Dan Scheurell Boeing D&SG - AWACS Advanced Products daniel.j.scheurell@boeing.com
