Upgrading or Downgrading ROM Monitor
The following procedure upgrades or downgrades the ROM monitor using the six ROM monitor upgrade
files, which are distributed in a compressed (*.tar) file.
Prerequisites
Before starting the procedure described in the next section, do the following:
• Determine if there is an upgrade tar file for your version of IOS XR. If only one tar file is listed on
the upgrade web site, no updates are available. You can display the ROM monitor tar files at the
following URL:
http://www.cisco.com/cgi-bin/tablebuild.pl/crs1rommon
• To prepare for a ROM monitor upgrade, copy the tar file to a workstation that has the software to
decompress tar files, then decompress the files.
