In 2N model only one SU (say SU1) will be active for all SIs and another SU(say SU2) will be standby for all SIs. So even if 5 SUs are present, one SU1 will be active and another SU2 will standby on behalf of all the SIs in the system. Other SUs are referred as spare SUs.
Let us suppose SU1 hosted on card1 is active for SI1, SI2,SI3 .... and SU2 hosted on card2 is standby for SI1,SI2, SI3.... If card1 reboots, then standby SU2 will become active on behalf of all the SI1,SI2,SI3 .... and others pare SU3 will become new standby. Now if card1 again comes up SU1 will not be given any role on behalf of all the SIs because SU2 is active and SU3 is standby for all SI1,Si2,SI3....
