4. Activate the selected startup configuration for One Time Boot.
5. Restart the board.
6. Activate the new startup configuration permanently
A software release for the AT8901M consists of one software package initrd, which includes
kernel and application software). The package is a tar archive containing an image of the soft-
ware and a MD5 checksum file for consistency check. The name of the package file is arbitrary
but the file names in the archive must not be altered.
When performing a firmware update, the software package is loaded from a remote TFTP serv-
er in the first step. This is done by means of the frontpanel FE port of the Hub board. To load a
software package via TFTP into a specified slot, the CLI command 'download' is used:
(Base
Fabric)
bolt-GA-3.06.pkg B
Downloading image, this may take a while...
Successfully
transferred
bolt-GA-3.06.pkg to slot 2
You may mark it active now and reboot to use the new kernel image.
(Base Fabric) #
This downloads the specified initrd package file via TFTP and writes the kernel image into the
kernel partition of the specified slot (B). The MD5 checksum of the kernel image is checked be-
fore writing it into flash. It is important not to overwrite the slot containing the currently active
software, otherwise the One Time Boot mechanism does not make sense.
After the software image has been downloaded into flash, the configuration slot for base and
fabric switch must be selected. In case that no appropriate configuration for base and fabric
switch is available, the factory default configuration for base and fabric switch should be used
for the startup configuration of the new software release. Alternatively, the running configura-
tion settings of base and fabric switch can be stored on flash using the following CLI command:
(Base Fabric) #copy system:running-config nvram:startup-config slot 3
This operation may take a few minutes.
Management interfaces will not be available during this time.

Finally, a startup configuration containing the slots of the new software release and the config-
uration slots must be selected or a new startup configuration must be created as described
above. After this step has been completed, the startup configuration is activated only for the
next boot and the board is rebooted. This is done with the 'startupslot' CLI command in the con-
figure mode:
(Base Fabric) (Config)#startupslot 3 activate once
#download
