Troubleshooting Routers
A-2
System Startup
The following sample message is from a log of a Series 7 router after we restarted
it by entering the
boot 2:- 2:log.cfg command. This message indicates that the
system is preparing the router software image:
@ 29: mm/dd/yy 11:48:14.507 DEBUG # 2 BOOT ( 12) Image is in
compressed format... decompressing
The boot PROM generates the following message for each slot. This message
shows the revision of the boot PROM on the FRE processor module, not the
revision of software.
@ 12: mm/dd/yy 11:47:57.007 INFO # 3 GAME ( 11) Starting image
rel/
<revision_no.>
/boot Day MMM DD 00:12:43 EDT yyyy
Because the router received instructions to perform a named boot (that is, it
received instructions to boot with a specified router software image or
configuration file on a specified slot, Slot 2), the system does not query the
backplane for the router software image; Slot 2 becomes the server of the router
software image. The router bootstraps the loader software and loads the router
software image (in this example, bn.exe) from the memory card in Slot 2.

FSM (finite state machine) messages indicate slot-to-slot communication. Each
slot is in one of four different states: “DOWN,” “SYNC,” “ACTIV” (active), and
“HOLD.”
