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.
