The following example shows how to set the configuration register on the DSC to 0x2. Setting the configuration registration to 0x2 causes the router to boot the Cisco IOS XR software and enter EXEC mode during a router reload.
Use the reload command to cause the RSP to reload the Cisco IOS XR software according to the configuration register setting (for example, 0x0 to enter ROMMON mode and 0x2 to reload the RSP to EXEC mode). If a standby RSP is in the ready redundancy state, the reload command also causes the router to fail over to the standby RSP. Use the show redundancy command in EXEC mode to display the status of the standby RSP.

If a standby RSP is not installed or is not in the ready state, then the router experiences a loss of service while the active RSP is reloading Cisco IOS XR software. To view the status of the standby RSP, issue the show redundancy command in EXEC mode.
In the following example, the show system backup command is entered with the details keyword to display additional information about the configuration and software package files stored on the backup device. Because this command is entered in administration EXEC mode, the backup information for both the administration and SDR configurations is displayed.
Use the system boot-sequence command with the target-device argument to specify the local storage device for backup software and configuration files. The target-device argument is optional and applies only to the current backup operation.
The following example shows how to define the primary and secondary boot device for the active RSP (DSC). In this example, the default location for software and configurations is disk0:. The location for backups of software and configurations is disk1:. 2ff7e9595c
