The chassis system can be configured for two‐module management redundancy using cli
command: set license redundancy <license key>
For information on how to use this command, refer to the Enterasys Matrix DFE‐Gold Series
Configuration Guide. To access this guide on the web, refer to "Related Documents" on
page xvi.
Rule: By default, the operation of all modules, except for the one in slot 1, can be lost
without loosing system operation. With the redundancy key installed, the system will
remain in operation provided the module in slot 1 or 2 is operational.
Example 3 (Figure
Shows the module missing from slot 1. As long as the redundancy key has been
programmed into the system and the module in slot 2 is operational, the system will
continue to operate.
Caution: When installing a module into slot 1 of a non-operating chassis, it is strongly
recommended that the module have the desired version of firmware. Installation of a
replacement module into slot 1 of a non-operating chassis requires reconfiguration of the
system settings.
Precaución: Para instalar un módulo en la ranura 1 del chasis apagado, lo mejor es que
el módulo corresponda a la versión de firmware solicitada. Para instalar un módulo de
reemplazo en la ranura 1 del chasis apagado será necesario reconfigurar el sistema.
Rule: You can power up the system completely as long as there is a module in slot 1. With
the redundancy key installed, you can power up the system completely as long as there is
an operating module in slot 1 or 2.
Example 4 (Figure
Shows a chassis populated with 4xxxxx modules in all slots except 1 and 2. This system is
not operational because there is no module in slot 1 or 2 for management purposes.
Rule: In a 4xxxxx system, the chassis system will not operate with modules missing from
slots 1 and 2.
Example 5 (Figure
Shows a chassis populated with 4xxxxx and 7xxxxx modules. DO NOT install 4xxxxx and
7xxxxx modules in the same chassis. In a 4xxxxx system, the chassis must be dedicated to
DFE modules only.
Rule: In a 4xxxxx system, the chassis must be populated with only 4xxxxx modules to
operate.
