Alcatel OS6850-48L Getting Started Manual page 37

Because slot 6 is the top-most switch in the stack, it is reas-
signed the slot 1 (i.e., primary) position; because slot 7 is
located immediately below slot 6, it is reassigned the slot 2
(i.e., secondary) position, etc.
When the stack comes up following the reboot, the manually-
configured slot numbers display as follows:
Slot 1 - Primary
Slot 2 - Secondary
Slot 3 - Idle
Slot 4 - Idle
Slot 5 - Idle
Slot 6 - Idle
Slot 7 - Idle
Slot 8 - Idle
