Checking the Boot PROMs
Make sure that the boot PROM images are compatible with the router software
image as follows:
1.
Enter the following command to display the software version of each boot
PROM:
get wfHwEntry.19.*
The number of the slot containing the boot PROM follows the dot (.) after the
object name wfHwEntry.wfHwBootPromSource.
Example
$ get wfHwEntry.16.*
wfHwEntry.wfHwBootPromSource.2 = "int/12.00/freboot.exe"
wfHwEntry.wfHwBootPromSource.3 = "int/12.00/freboot.exe"
wfHwEntry.wfHwBootPromSource.4 = "int/12.00/freboot.exe"
wfHwEntry.wfHwBootPromSource.5 = "int/12.00/freboot.exe"
2.
See the upgrade guide
to make sure that the boot PROM versions meet
the software version requirements.
Making Sure the Router Software Image Is Correct
Make sure that the router software image on the router is compatible with the type
of router you are using. See the upgrade guide for a list of the router software
image names and the associated router types.
Making Sure All Slots Use the Same Router Software Image
and Configuration File
Different versions of router software image and configuration files in a router can
cause serious problems. The best way to avoid these problems is to maintain
consistency among the router software images in multiple flash memory cards.
Also, make sure that, if you make a change to a configuration file on one flash
memory card, you copy the file to any other flash memory cards that have a file
with the same name.
If you specify the router software image and configuration files when booting the
router, all processors boot with the specified router software image and
configuration file.
