Installing and Operating BayStack ARN/DC Routers

116273-B Rev 00
When you start the ARN/DC for the first time, it completes an initial startup
procedure to boot and connect to the network using either a default configuration
file or one already customized and available on the network.
You use one of four boot options to complete the initial software startup. Table 2-1
summarizes the four options; the sections that follow provide steps for completing
each option.

File Description and Requirements
EZ-Install Local Network
(serial interface
only)
The default option. The ARN/DC boots from local flash
memory, then obtains its configuration file from a remote
workstation that is configured as a Bootstrap Protocol
(BootP) server. The ARN/DC saves the configuration to the
Flash memory.
This option requires a High-Level Data Link Control (HDLC)
or frame relay serial connection.
Netboot*
* The ARN/DC supports netboot over serial, Ethernet, and 56/64K DSU/CSU interfaces only.

The ARN/DC locates and obtains
at least one
startup file
from a remote workstation that is configured as a BootP
server.
This option requires a communications connection over an
HDLC, frame relay, Ethernet, or DSU/CSU interface, and a
local console connection.
Directed

The ARN/DC obtains
at least one
startup file from a remote
workstation that is configured as a Trivial File Transfer
Protocol (TFTP) server. You must specify the IP address of
the TFTP server and the complete path to the startup files
before booting.
This option requires a communications connection over an
HDLC, frame relay, Ethernet, or DSU/CSU interface, and a
local console connection.
Local
Boot
Local Local The ARN/DC boots from a local software image and generic
startup configuration file. You create a customized
configuration file by running the Quick-Start script.
This option requires a local console connection and an
installed BayRS flash memory card. If you attempt to local
boot the ARN/DC without the flash memory card inserted,
the router does not operate.
