but the entire file will not be copied into Flash memory.
Fast Software Upgrade Example
The following example show a Fast Software Upgrade performed on a Cisco 7507 router with an active
RSP in slot 2 and a standby RSP installed in slot 3.
Router# copy tftp slot0:rsp-pv-mz
Router# copy tftp slaveslot0:rsp-pv-mz
Router# configure terminal
Router(config)# hw-module slot 2 image slot0:rsp-pv-mz
Router(config)# hw-module slot 3 image slot0:rsp-pv-mz
Router(config)# end
Router# hw-module sec-cpu reset
Router# copy running-config startup-config
Router# redundancy force-switchover
Configuring SLCR
The Cisco 7500 SLCR feature is disabled by default. Therefore, the process for disabling this feature is
only necessary if the Cisco 7500 SLCR feature has been enabled by the user on the Cisco 7500 series
router.
Enabling SLCR
To enable the Cisco 7500 Single Line Card Reload (SLCR) feature, use the service
single-slot-reload-enable global configuration command on the Cisco 7500 series router.
Command
Router(config)# service single-slot-reload-enable
