Preparing an Image
If you want the router to automatically boot a network-based image when starting
up (using Netboot or Directed Netboot), use the Site Manager Image Builder tool.
To create the kernel, application, and string files for storage on the BootP/TFTP
server:

Record the name of each configuration file and corresponding router for
later reference when configuring network boot options.
When you name configuration files, keep the following restrictions in mind:
•
Nortel Networks recommends that the operational configuration file for
each router be named config. If a router experiences a power failure, it
boots from the file named config when power returns. However, the
configuration files that you save on a BootP server for Directed Netboot
do not have to be named config because you specify the configuration file
path name (see the description of the Site Manager parameter Boot
Config Pathname on page A-3.)
•
Configuration file names must begin with an alphabetic character. The
remaining characters must be alphanumeric and can include an
underscore (_). You cannot use spaces.
•
Configuration file names can consist of 1 to 15 characters, including a
dot (.). Nortel Networks recommends that you limit file names to 8
characters to ensure that all supported operating systems can recognize
the names.
•
Configuration file-name extensions are optional and must follow a file
name and a dot. Nortel Networks recommends that you limit file-name
extensions to three characters.
•
BootP allows a maximum of 49 characters in a path name, including
slashes, file name, optional dot, and file-name extension.
If the BootP server and Site Manager do not reside on the same
workstation, transfer the configuration files to the BootP server.
On the Site Manager workstation, open the software image file using the
Image Builder tool.

Managing Routers with Site Manager.
