Reloading an MRV

To recover an MRV which loads the ppciboot menu but boots no further, try re-installing the software image (linuxito.img) with the following procedure. If the MRV boots, you can upgrade the software (and/or ppciboot) using the update command from the CLI.

Software

The two MRV software image files (ppciboot.img and linuxito.img) are on the CD you lost when you installed it! They're hiding in the /software folder. Alternatively, you can download the images from support.mrv.com, but this requires a service agreement and login.

Having found the software images, you will need a TFTP server on your network to upload them to the MRV.

Copy the file linuxito.img into the TFTP servers root directory, and set the server to allow incoming connections.
