Enterasys Networks XSR-3020 - Manual (Page 78)

XSR Rebooting Characteristics
3-34 Software Configuration
Power-Up Reboot
If you power cycle the XSR by flipping the switch on the back panel, the XSR will cold reboot. The
startup-config file 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-config file.

After power-up, the XSR comes up automatically if:
• The minimum hardware is functional: Processor, RAM and FLASH memory, and other
components.
