Maintaining the Router Software

The BayStack router file system resides on the flash memory card, which is not

user serviceable.

You use Technician Interface commands to maintain the local file system on the

BayStack router flash memory card. For more information, see Using Technician

Interface Software and Using Technician Interface Scripts.

When Technician Interface commands require that you specify a volume, always

specify volume 1 for a BayStack router.

Upgrading the Software Image

You can upgrade a BayStack router’s kernel file (krnl_an.exe for the AN/ANH or

krnl_arn.exe for the ARN) using one or both of the following options:

• Use Netboot to start the router.

This option upgrades the image only in the BayStack router’s RAM.

• Use TFTP to transfer the image to the BayStack router’s flash memory card,

then use Local Boot to start the router.

This option upgrades the image in both the BayStack router’s flash memory

card and in RAM.

Caution:

Be very careful when you use the

format

command. This command

erases all files on the local flash memory card, and the BayStack 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 memory card. See

Using Technician Interface Software or Configuring and Managing Routers

with Site Manager.

Caution:

If you use TFTP to transfer an upgraded image to a BayStack router

flash memory card, and the file transfer is interrupted (for example, if the

router resets, reboots, or loses power), the BayStack router’s local file system

on the flash memory card becomes corrupted and the router cannot boot

locally until you restore the file system.
