3-1 Remote Annex 4000 Hardware Installation Guide
Chapter 3 ROM Monitor Commands
T
his chapter describes the ROM Monitor commands. Access these
commands through a terminal connected to the console port when
the Remote Annex 4000 is intest mode.
Pressing the Test button within 3 seconds of powering up puts
the Remote Annex 4000 into test mode. To enter test mode
when the Annex is already running, hold down the Test button
until the Power LED blinks rapidly, then release the Test button
and press it again within 3 seconds. This second method resets
the Annex, so warn users before you do it.
If you try to access the ROM monitor and receive a password
prompt, contact your system administrator. The ROM monitor
is password protected.
The ROM Monitor commands allow you to set a subset of the
configuration (EEPROM) parameters. Some of these parameters, like
the unit’s IP address, are required for booting the Remote Annex 4000;
some parameters, like the broadcast address, are required if the
network configuration differs from the supplied defaults. Table 3-1
lists the ROM Monitor commands.
Other parameters, although not required, are recommended for the
Remote Annex 4000’s initial boot. Setting these parameters, rather
than using the assigned defaults, minimizes errors during the initial
boot. For example, setting the parameter that defines the preferred
load host enables the Remote Annex 4000 to load by requesting
assistance from a specific host, rather than by broadcasting that
request to all hosts on the subnet.
After the Remote Annex has booted, you can define the same
parameters you defined using the ROM monitor, by using the na
utility, the local CLI admin command, or SNMP (for more details, see
the Remote Annex Administrator’s Guide for UNIX).
