The Model 8000 RAC supports an optional compression/decompression
daughter card that utilizes the Stac 9711 coprocessor to implement high-
speed LZS and MPPC.
The RAC ROM contains firmware for performing power-up self-tests and
loading operational code. A nonvolatile EEPROM stores the
configuration parameters.
The RAC can boot from the boot image in its flash memory or can boot
an image received from a boot server on the network.
The ROM monitor is an interactive command interpreter that is used to
define basic configuration parameter values. You define the information
that the Model 8000 RAC needs to boot an operational image using the
ROM monitor and its command set. ROM monitor commands are issued
from a terminal connected to the console port on the rear panel. When
the RAC completes its self-tests, the console terminal displays the ROM
monitor prompt. Using the ROM Monitor commands (see Chapter 3),
you can:
• Modify and display a set of configuration parameters stored
in EEPROM.
• Execute interactive diagnostic tests.
• Receive information and statistics for the hardware
configuration and the network.
• Boot the RAC manually.
