Reverting To The Dynamic Slot Numbering Model - Alcatel OS6855-24 Hardware User's Manual

Slot Numbering
Because slot 6 is the top-most switch in the stack, it is reassigned 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.
Note that the modules were not reloaded one-by-one, even though the stack set slot command provides
optional syntax for doing so. Instead, new slot number information is first saved to each boot.slot.cfg file
across the stack. The reboot is saved for last in order to avoid duplicate slot numbers within the stack,
which would cause unwanted pass-though mode conditions (see
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
The stack set slot command can also be used to manually correct duplicate saved slot assignments within
the stack topology. Refer to pages
Note: The diagram above is for example purposes only, currently only four OS6855-U24X switches can
be stacked at a time.

Reverting to the Dynamic Slot Numbering Model

To clear the boot.slot.cfg files from the stack's /flash directories, use the
modules and then reboot the stack. For example:
-> stack clear slot 1
-> stack clear slot 2
-> stack clear slot 3
-> stack clear slot 4
-> stack clear slot 5
-> stack clear slot 6
-> stack clear slot 7
-> stack clear slot 8
-> reload all
The commands shown above clear the saved slot information from all modules in a stacked configuration
and then reboot the stack. Because the system software no longer has preassigned slot information to read
during the boot process, the stack uses the dynamic slot number assignment method described on
7-21.
