Bay Technical Associates none manual Understanding the ARN Boot Options

Installing and Operating BayStack ARN Routers

You must complete an initial startup procedure to obtain the executable and default configuration files and connect the ARN to the network. Getting a file over the network is called network booting, or netbooting. Getting a file from the ARN file system, stored in Flash memory, is called local booting.

Caution: The ARN must contain a Flash memory card if you plan to obtain any startup files through the local boot procedure. If you attempt to local boot the ARN without the Flash memory card inserted, the router does not operate. Refer to “Installing the Flash Memory Card” in Chapter 1 for instructions.

Understanding the ARN Boot Options

You use one of four boot options to complete software installation: EZ-Install, Netboot, Directed Netboot, or Local Boot. Table 2-1 summarizes the four options; the sections that follow provide steps for completing each option.

Table 2-1.	Summary of Initial Startup Options
		Source for
Boot	Source for	Configuration
Option	Image file	File	Description and Requirements
EZ-Install	Local	Network	The default option. The ARN boots from local Flash
		(serial interface	memory, then obtains its configuration file from a remote
		only)	workstation that is configured as a Boot Protocol (BootP)
			server. The ARN saves the configuration to the Flash
			memory.
			This option requires a High-Level Data Link Control
			(HDLC) or Frame Relay serial connection.
Netboot*	Local	Local	The ARN locates and obtains at least one startup file
	or	or	from a remote workstation that is configured as a BootP
	Network	Network	server.
			This option requires a communications connection over
			an HDLC, Frame Relay, Ethernet, token ring, or
			DSU/CSU interface, and a local console connection.
