Booting a Processor Module
To troubleshoot a router problem, you can boot a processor module to determine
whether the module is the problem. To boot an individual processor module, you
use the Reset Slot option in the Administration menu in the Site Manager menu
bar. The Reset Slot option warm-starts a single processor module in the router
with the boot image and configuration file that the router is currently using.
The following steps explain what happens when you boot a processor module:
1. The router software that is operating on the processor module forwards a boot
request to the other processor modules.
2. The first processor module that responds to the boot request sends back the
boot image resident in its memory to the requesting module.
3. The processor module that you are booting receives and executes the boot
image. The router disrupts connectivity to the associated slot and to the
services provided by that slot. The other processor modules resynchronize
their routing tables after the slot fails to receive packets.
4. The processor module that you are booting completes the boot process and
requests a configuration. The first available processor module sends the
configuration resident in its memory.
5. The resetting processor module loads the configuration image and initiates the
services provided by the slot, thus reestablishing connectivity. It then alerts
the other processor modules that it can receive packets.
6. The other processor modules resynchronize their routing tables accordingly.
