After the RAC obtains a boot image and is booted, it displays the Console
monitor (for more details, see Chapter 2).
The Model 8000 RAC can self-boot from the image contained in its flash
memory. The RAC can also obtain full operational code over the network
from one of the following devices:
• UNIX host
• Another Model 8000 Remote Access Concentrator
configured as a load server
• NT host
The Model 8000 RAC uses a watchdog timer that is reset by the software
at regular intervals. The watchdog timer reboots the RAC in the unlikely
event of an internal software error. This feature enables the RAC to run
for long periods of time without intervention.
