Unless the hardware can auto-detect cable types, you have to use the
same cable wiring (straight, cross-over) regardless of the mode.  The
xmit/rcv lines have to be properly connected (think of connecting the
handsets of two phones so that people on both ends can talk)

Crossover cables are used when you go from end device to end device, or
from two intermediate devices (eg. switch to switch).  Straight-through
cables are used from end device to intermediate device (switch), etc. 
But cable-detecting hardware loosened those rules.

Mustard - back to your question.  Do you see the "link" light when you
plug the cable between your server and the SB2?  That would be the
light that comes on immediately at the ethernet jack on either system. 
If you do, then that cable is correct.  If not, then you need a
straight-though cable.

Once you have "link" (means the two ethernet devices have partnered at
the physical layer, and are at least hardware-wise communicating), then
its on to the next higher layer.  This is where device-to-device
communication can fail.  The speed and duplex must be appropriate and
match on both partners.  Many chip pairings have trouble
auto-negotiating the proper settings, and many pairings, as i've
mentioned, cannot reliably handle 100 full duplex when
device-to-device.

Please confirm you have link.
