Understanding Core Dump Messages
If you configure the switch to write core dump (debug) files to the internal memory card and
attempt to download a new software image, you might have insufficient space to complete
the image download. If this occurs, move or delete the core dump files from the internal
memory. For example, if you have a modular switch with an external memory card installed
with space available, transfer the files to the external memory card.

The switch displays a message similar to the following and prompts you to take action:
Core dumps are present in internal-memory and must be removed before this
download can continue. (Please refer to documentation for the “configure debug
core-dumps” command for additional information)
Do you want to continue with download and remove existing core dumps? (y/n)

Installing a Modular Software Package
In addition to the functionality available in the XCM8800 core image, you can add
functionality to your switch by installing modular software packages. Modular software
packages are contained in files named with the file extension
functionality to your switch by installing modular software packages. Modular software
packages are contained in files named with the file extension
.xmod
, while the core images
use the file extension
.xos
. Modular software packages are built at the same time as core
images and are designed to work in concert with the core image, so the version number of a
modular software package must match the version number of the core image that it will be
running with. For example, the modular software package for Secure Shell (SSH) named as
follows:
modular software package must match the version number of the core image that it will be
running with. For example, the modular software package for Secure Shell (SSH) named as
follows:
ng8800-11.2.0.18-ssh.xmod
Can run only with the core image named:
ng8800-11.2.0.18.xos
You can install a modular software package on the active partition or on the inactive partition.
You would install on the active partition if you want to add the package functionality to the
currently running core image without having to reboot the switch. You would install on the
inactive partition if you want the functionality available after a switch reboot.
