The 3 x 8 module is installed to expand system capacity and is housed in the KSU in

The 6-Port CO Module must be installed in the last available expansion bus connector on
the CPU Module. That is, if a 6-Port CO Module is installed on (JP3) a 3 x 8 module will not
function if installed on (JP4). So, if a 3 x 8 module is added after a 6-Port CO Module was
previously added, the 6-Port CO Module must be removed from (JP3), the new 3 x 8 module
installed to (JP3) and the 6-Port CO Module reinstalled onto (JP4).
