Power-Up Reboot

If you power cycle the XSR by flipping the switch on the back panel, the XSR will cold reboot. The startup-configfile stored in Flash becomes the running configuration.

Reload Command from the CLI

You can reboot the XSR firmware by issuing the command reload <cold warm>. You are then prompted to confirm the command. Once the firmware is reloaded, the configuration is loaded from the startup-config file.

Bootrom Monitor Commands bc and bw

Using Bootrom Monitor mode, you can activate warm or cold reboots by entering bw or bc, respectively. Refer to “Bootrom Monitor Mode Commands” on page 3-35 for more data.

Watchdog Timer Expiration

When the internal watchdog timer expires, causing the XSR to fail, fault information is captured in a report and a warm boot is initiated. But if more than three warm boots are detected within one minute, a cold boot will be initiated.

System Crash

When system exceptions occur causing the XSR to fail, fault information is captured in a report and a warm boot is initiated. But if more than three warm boots are detected within one minute, a cold boot will be initiated.

Restart with Default Configuration Interrupt

When you press the Default button on the back panel, the XSR restarts using factory default parameters, ignoring the startup-configfile.

Power-up Error Conditions

After power-up, the XSR comes up automatically if:

•The minimum hardware is functional: Processor, RAM and FLASH memory, and other components.
