Verifying IOS Canned Version of the CF Memory Card
Overview
This section covers the procedures and commands required to verify the
IOS version loaded on BTS router CF memory cards and copy standard
canned configuration files to the routers. Because of the set–up required
and the length of some of the procedures, Motorola recommends
performing the actions covered in this section at a central location to
prepare the BTS routers for installation prior to the site visit.
IOS Version Verification and File Sequence Position
Version verification – The IOS version loaded on the BTS router CF
memory card should be verified as the version required for operation on
the network where the routers will be installed. If the loaded IOS version
is not correct, it can be replaced with a different version. There are
several methods available to accomplish version verification. These
depend on the equipment and software applications the user selects to
use in installing the canned configuration files in the BTS routers.
Appropriate verification procedures are included in each of the two
canned configuration installation methods covered in this section.
Methods to change the loaded IOS version are provided in the Change
BTS Router IOS Version section of this appendix and are referenced at
the appropriate places in the canned configuration installation methods.
File sequence position – During initialization, the MWR 1941 router
will first search the
startup–config file for a boot system command
line telling it in what directory and file to find the boot loader. If this line
is not found, the router will default to attempting to boot from the first
file in its flash memory. Flash memory for the MWR 1941 is the CF
memory card (software identifier slot0:). The canned configuration files
used for BTS router installation do not contain a boot system command
line because of the need to maintain flexibility for IOS version changes.
Because of this, it is critical that the IOS file is the first file listed on the
CF memory card. The canned configuration installation procedures
contain steps to assure that this is the case, and, if it is not, provide
guidance to correct the condition. It is important to remember that, if the
router boots and displays a
rommon 1 > prompt, the IOS file is
missing, out of sequence, has a corrupted flash memory image or the
startup–config file contains a boot system line which specifies a
missing or incorrect IOS pathname/filename.
Canned Configuration File Installation
Filename and installation location requirements – The canned
configuration files for the BTS routers must be copied to the CF memory
card. The filename of the file on the CF memory card must be
canned–config. Canned configuration file location and filename
requirements are a result of Mobile Wireless Center (MWC) actions
during the process of switching a BTS from packet to circuit mode. In
this process, the MWC will query the BTS routers’ slot0: directory for a
file named
canned–config. A missing or mis–named file will cause
problems with execution of the mode–switching process.
