360 BLACK BOX ® Advanced Console Server
If the BLACK BOX ® Advanced Console Server booted properly, the interfaces can be
verified using ifconfig and ping. If ping does not work, check the routing table using
the command route. Of course, all this should be tried after checking that the cables
are connected correctly.
The file /etc/config_files contains a list of files acted upon by saveconf and
restoreconf. If a file is missing, it will not be loaded onto the ramdisk on boot. The
following table lists files that should be included in the /etc/config_files file and
which programs use each.
Note: Possible causes for the loss of flash memory may include: downloaded
wrong zImage file, downloaded as ASCII instead of binary; problems with flash
memory.
