BigIron RX Series Configuration Guide 3353-1001986-01Monitoring management module redundancy 3BigIron RX# boot system flash primarySyntax: boot system bootp | [flash primary | flash secondary] | slot | tftp The flash primary keyword specifies the primary RX Series IronWare image in the managementmodule’s flash memory, while the flash secondary keyword specifies the secondary RX SeriesIronWare image in the flash memory.For the parameter, specify 1 for PCMCIA slot 1 on the active management module and 2for PCMCIA slot 2 on the active management module. For the parameter, specify thename of the image on the PCMCIA flash card.The tftp keyword directs the BigIron RX Series Switch to boot from an RX Series IronWare image ona TFTP server located at with the specified .For example, to reboot the active and standby management modules, enter the following commandat the Privileged EXEC level.BigIron RX# reloadSyntax: reloadTo reboot the standby module only, enter the following command at the Privileged EXEC level.BigIron RX# reboot-standbySyntax: reboot-standbyMonitoring management module redundancyYou can monitor the following aspects of management module redundancy:• The status of the management modules (if a module is the active or standby module).• The switchover history for the management modules.The following sections explain how you can monitor the management modules.Determining management module statusYou can determine the status of a management module in the following ways:• LEDs – The management module’s LEDs indicate whether a module is the active module orthe standby module, and if the module has power.• Module information in software – The module information displayed by the software indicateswhether a module is the active module or the standby module.Status LEDIf you are located near the BigIron RX Series chassis, you can determine which managementmodule is currently the active module and which is the standby module by observing the Active LEDon each module. If this LED is on (green), the module is the active module. If this LED is off, themodule is the standby module.You can also observe the Pwr LED on each module. If this LED is on (green), the module is receivingpower. If this LED is off, the module is not receiving power. (A module without power will notfunction as the active or standby module.)
