AI2524 Router Card User’s Manual

If the configuration was modified but not saved, you are asked to save the configuration:

System configuration has been modified. Save? [confirm]

If you confirm to save the configuration, you might also receive this message:

Warning: Attempting to overwrite an NVRAM configuration previously written by a different version of the system image. Overwrite the previous NVRAM configuration? [confirm]

Users with open Telnet connections are notified of the system reload, as:

**System going down for Flash upgrade**

If the TFTP process fails, the copy operation is retried up to thre times. If the failure happens in the middle of a copy operation so only part of the file has been written to Flash memory, the retry does not erase Flash memory unless you specified an erase operation. Th partly written file is marked as deleted, and a new file is opened with the same name. If Flash memory runs out of free space in this process, the copy operation terminates.

After Flash load helper finishes copying (whether or not the copy op- eration is successful), it automatically attempts an automatic or a man- ual boot, depending on the value o f bit0 of the configuration registe boot field:

zBit 0 = 0 The system attempts a default boot from Flash memory to load the first bootable file in Flash memory. This default boot is equivalent to a manual b flash command at the ROM monitor prompt.

zBit 0 = 1 The system attempts to boot based on the boot configuration commands. If no boot configuration commands exist, the system attempts a default boot from Flash memory; that is, it attempts to load the first bootable file in Flash memory.
