24 Completing a Stacked Configuration March 2005
All switches in the stacked configuration should now be
placed in their proper location (e.g., tabletop to rack). In order
to complete the stacked configuration process, you must
complete the following steps:
1 Individually assign slot numbers to all switches
2 Attach all required stacking cables
3 Boot the newly-configured stack
For OmniSwitch 6600 Family switches, the term “slot” refers
to the priority status of the switch within the stacked configu-
ration. Slot numbers may range from 1 to 8.
Slot Assignment Guidelines
Before assigning slot numbers to switches in a stacked config-
uration, note the following guidelines.
• Slot numbers do not need to be sequential. However,
each switch in a stack must have a unique slot number.
If duplicate slot numbers are encountered, an error will
occur and the stack will be disabled.
• The top switch in the stack does not have to be desig-
nated as slot 1.
• By default, the primary—or management—role will be
given to the switch with the lowest chassis MAC
address. All other switches in the stack will be in non-
operational status until slot numbers are assigned by
the user and the stack is manually rebooted.
• After manually assigning the slot assignments for all
switches and rebooting the stack, the primary role will
be given to the switch with the lowest slot number. The
secondary role will be given to the switch with the
next-lowest number. All additional switches with
higher numbers will be given idle status. For more
information on primary, secondary, and idle roles, refer
to the “Managing OmniSwitch 6600 Family Stacks”
chapter in the OmniSwitch 6600 Family Hardware
Users Guide.
• Changing the slot number of a chassis does not imme-
diately change its management role (i.e., primary,
secondary, or idle). You must reboot all the switches in
the stack before these changes will take effect.
Refer to the illustration on page 26 for one of many valid
slot numbering possibilities.
Follow the steps beginning on page 25 to assign slot numbers
for OmniSwitch 6600 Family switches.
