Because the documentation is misleading...

Sarnath, Dan is completely correct, it is relative so you need to first *carefully read* the comments in sandpoint_setup.c that describe the switch setting,
*understand them*, and then *follow them*.   Especially the part where it says:


     " * 'down' is in the direction from the PCI slots towards the PPMC slot;
      * 'up' is in the direction from the PPMC slot towards the PCI slots.
      * Be careful, the way the sandpoint board is installed in XT chasses will
      * make the directions reversed."
