RE: [10GBASE-CX4] Cable / Connector pinout




Hi Howard,

I am looking at the spec and find that the
cable signals are consistent with my draft
and your stated IB Signal is different.

The document I hold, Volume2 rev 1.0a has 
change bars on those signals as if they were
the most recent change.

This suggests you *may* be looking at an old
draft. (please oh please oh please!!)

Can someone more familiar with this matter
please reply to this?

Thanks,

Dan

All,
	I just noticed that the connections for the Cable assemblies we have
been dealing with do not match the connections in the IB specification. 
Here is what I have determined:
IB  IB        Cable
Pin Signal    Signal    Difference
S1  IBtxIp(3) IBtxIp(0) X
S2  IBtxIn(3) IBtxIn(0) X
S3  IBtxIp(2) IBtxIp(1) X
S4  IBtxIn(2) IBtxIn(1) X
S5  IBtxIp(1) IBtxIp(2) X
S6  IBtxIn(1) IBtxIn(2) X
S7  IBtxIp(0) IBtxIp(3) X
S8  IBtxIn(0) IBtxIn(3) X
S9  IBtxOn(3) IBtxOn(3) 
S10 IBtxOp(3) IBtxOp(3) 
S11 IBtxOn(2) IBtxOn(2) 
S12 IBtxOp(2) IBtxOp(2) 
S13 IBtxOn(1) IBtxOn(1) 
S14 IBtxOp(1) IBtxOp(1) 
S15 IBtxOn(0) IBtxOn(0) 
S16 IBtxOp(0) IBtxOp(0) 

The Cables IBtxI lane order is reversed from the IB Specification.  I am
looking at "InfiniBand Architecture Release 1.0 Volume 2 - Physical
Specifications" page 160 & 161, table 24.
