Dell Force10 S4810P Configuration Manual page 981

With FTOS 8.3.12.0, when a unit is added to a stack, the management unit performs a system check on the
new unit to ensure the hardware type is compatible. A similar check is performed on the FTOS version. If
the stack is running 8.3.12.0 and the new unit is running an earlier software version, the new unit is put into
a card problem state.
• If the unit is running version 8.3.10.x, it is upgraded to use the same FTOS version as the stack,
rebooted and join the stack.
• If the new unit is running an FTOS version prior to 8.3.10.x, the unit is put into a card problem state,
FTOS is not upgraded, and a syslog message is raised. The unit must be upgraded to FTOS 8.3.12.0
before you can proceed.
Syslog messages are generated by the management unit:
• before the management unit downloads its FTOS version (FTOS 8.3.12.0 or later) to the new unit. The
syslog includes the unit number, previous version and version being downloaded.
• when the firmware synchronization is complete.
• if the system check fails, a message such as a hardware incompatibility message or incompatible uboot
version is generated. If the unit is placed in a card problem state, the management unit also generates
an SNMP trap.
• if the software version of the new unit predates FTOS 8.3.12.0, the management unit puts the new unit
into a card problem state and generates a syslog that identifies the unit, its FTOS version, and its
incompatibility for firmware synchronization.
Note: You must enter the
stack to ensure the units are assigned to the correct groups.
Note: Any scripts used to streamline the stacking configuration process must be updated to reflect the
Command Mode change from EXEC to CONFIGURATION to allow the scripts to work correctly.
Enable Front End Port Stacking
To enable the front ports on an S4810 unit for stacking, use the following procedure.
Note: Once a port has been allocated for stacking, it can only be used for stacking. If stack-group 0 is
allocated for stacking, then ports 0, 1, 2, and 3 can be used for stacking but not for Ethernet anymore. If
One a
only port 0 is used for stacking, ports 1, 2, and 3 are just spare; they cannot be used for Ethernet.
After the front ports are enabled, use the
Task
Assign a stack group for each unit. Begin with the first port
on the management unit. Next, configure both ports on
each subsequent unit. Finally, return to the management
unit and configure the last port. (See the example below.)
