Installing and Operating BayStack ARN Routers
2-4 114200 Rev. A
Starting the ARN for the First Time
The ARN factory defaults are set to find the configuration and image files from the
following locations:
• Configuration file -- over the network
• Image file -- on the local PCMCIA Flash memory card
These default settings work with the default EZ-Install procedure.
The first time you power on an ARN, the router steps through its diagnostic tests
and then attempts to boot over all of its serial (COM) interfaces using EZ-Install.
If your network administrator has configured the network for the EZ-Install
procedure, the router boots using its local image and obtains its configuration file
over the network. Your network administrator can then connect to the ARN and
manage it remotely. Refer to the next section, “Using EZ-Install,” for more
information.
If your network administrator does not configure the network for EZ-Install, the
ARN cannot obtain its configuration file from the network, and the EZ-Install
procedure fails. The ARN then attempts to boot locally with the configuration file
that resides on its Flash memory card. Refer to “Using Netboot, Directed Netboot,
or Local Boot” for more information.
If both the EZ-Install and local boot attempts fail, the EZ-Install and local boot
processes repeat until one of the following occurs:
• The ARN boots successfully.
• You interrupt the boot process to enter the ARN monitor.
• You turn off the ARN.
The following sections describe how to use each of the different boot options for
the ARN.
