Example 2 (Figure 3-5, B)
Shows the chassis fully populated with 4xxxxx modules. By default, the chassis system
can continue to operate after loosing operation of all modules except the module in slot 1.
(The loss of operation can be due to module reset, removal, or failure.) However, with the
redundancy key installed, the system will remain operational provided that there is an
operating module in slot 1 or 2.
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 Matrix DFE-Gold Series
Configuration Guide. To access this guide on the web, refer to “Related Documents” on
page xv.
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 3-5, C)
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.
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 3-5, D)
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.
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.
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. When instating a
replacement module into slot 1 of a non-operating chassis, it is necessary to reconfigure
the system settings.
