Troubleshooting Network Boot Problems
A-15
Maintaining the Router Software
The AN/ANH file system resides on the Flash memory card. This part of the
router is not user-serviceable.
You use Technician Interface commands to maintain the local file system on the
AN/ANH Flash card. See Using Technician Interface Software and Using
Technician Interface Scripts for information.
When Technician Interface commands require you to specify a volume, always
specify Volume 1 for an AN/ANH.
Upgrading the Software Image
You can upgrade an AN/ANH’s software image (krnl_an.exe) using one or both of
the following options:
Use Netboot to start the AN/ANH.
This option upgrades the image only in the AN/ANH’s RAM.
Use TFTP to transfer the image to the AN/ANH’s local file system, then use
Local Boot to start the AN/ANH.
This option upgrades the image in both the AN/ANH’s local file system and in
memory.
Caution: Be very careful when you use the format command with the router.
This command erases all files on the local Flash card, and the router will not
be able to local-boot an image or configuration file until you replace the files.
You can avoid this situation by partitioning the Flash card media. See Using
Technician Interface Software and Managing Routers.
Caution: If you use TFTP to transfer an upgraded image to an AN/ANH Flash
card, and an interruption in the file transfer occurs (for example, if the
AN/ANH resets, reboots, or loses power), the AN/ANH’s local file system
becomes corrupted and it cannot boot locally until the file system is restored.
