4.2 Configuration File and TiMOS Image Loading

The bootstrap image processes the initialization parameters from the BOF and
attempts to locate the configuration file configured in the BOF. Up to three locations
can be configured for the system to search for the configuration file. The locations
can be local or remote. The first location searched is the primary configuration
location. If not found, the secondary configuration location is searched, and lastly, the
tertiary configuration location is searched.
If the configuration file is in a remote location, the bootstrap process saves it on the
flash as cf1:/default.cfg. Users must not delete this file or create a file with this name.
The configuration file includes chassis, IOM, MDA, and port configurations, as well
as system, routing, and service configurations.
Like the configuration file, three locations can be configured for the system to search
for the files that contain the both.tim (SR OS/TiMOS) image. The locations can be
local or remote. The first location searched is the primary image location. If not found,
the secondary image location is searched, and lastly, the tertiary image location is
searched.
Note: The configuration and image loading information described in this section applies to
all the 7210 SAS platforms with the following exceptions.

4.2.1 Boot Sequence and Image Loading
