Chapter 3 Troubleshooting PRE-1 Modules
PRE Module Not Supported
PRE Module Not Supported
The Cisco uBR10012 router supports only the PRE-1 module in Cisco IOS Release 12.2(8)BC1, and
later releases. If you attempt to boot the Cisco uBR10012 router with a PRE module with one of these
software releases, the router prints the following error message and falls through to the ROM monitor:
%%Error: PRE not supported with this image
rommon>
To correct this error, replace the PRE modules in the router with PRE-1 modules. To continue using the
original PRE modules, you must be reload the router with Cisco IOS Release 12.2(4)BC1 or an earlier
12.2 BC release.
Note For information on the replacement of PRE modules with PRE-1 modules, see the Field Notice,
Cisco uBR10000 Proactive Upgrade of PRE to PRE1, at the following URL:
