Model 5399 Remote Access Concentrator Module Hardware Installation Guide

The Model 5399 Remote Access Concentrator’s ROM contains firmware
for performing power-up self-tests and loading operational code. A non-
volatile EEPROM stores the configuration parameters.

The Remote Access Concentrator 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. All of the information that
the Model 5399 Remote Access Concentrator needs to boot an
operational image is defined using the ROM monitor and its command
set. ROM Monitor commands are issued from a terminal connected to
the service port on the hub chassis. When the Remote Access
Concentrator completes its self tests, the service port 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

Remote Access Concentrator

manually.

Once the Remote Access Concentrator has obtained a boot image and is
booted, the service port terminal leaves the ROM monitor and displays
the Console monitor (for more details, see Chapter 2).
