Firmware
ROM Monitor
The Remote Annex 5393/PRI's ROM contains firmware for
performing power-up self-tests and loading operational code. A non-
volatile EEPROM stores the configuration parameters.
The Remote Annex 5393/PRI can boot from the boot image in its Flash
memory or can boot from 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 Remote Annex 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 Annex 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 Annex manually.
Once the Remote Annex 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).
