Upgrading an MRV

You can upgrade the MRV software (and/or ppciboot) either using the update ppciboot and update software commands in the Superuser command mode (CLI), or directly from the ppciboot menu. The following describes the update command line procedure.

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 image files ppciboot.img and linuxito.img into the TFTP servers root directory, and set the server to allow incoming connections.

Command Line Interface

1Hook a serial console cable to the MRV Management (Diag) port, and open a terminal session: 9600, 8, N, 1.

Login (InReach/access), and enter the Superuser command mode:

In-Reach:0 >en
Password: system

2Enter the following commmand:

In-Reach:0 >>update ppciboot tftp_server_ip image name file_name

If successful, the “TFTP Download complete, verifying file integrity” message appears, and the loaded file is checked for integrity. If the check is successful, the “File OK, copying image to flash” message appears. You have upgraded ppciboot. If the check finds a problem, the “Verify failed, Bad ppciboot file” message appears.

You must reboot the unit for the new ppciboot to take effect.

3Enter the following commmand:

In-Reach:0 >>update software tftp_server_ip image name file_name

Updating software can take up to five minutes. You are copying from the TFTP server to the flash.

4Enter the following commmand to save your configuration:

In-Reach:0 >>save config flash

This stores the current parameters.

5Enter the following commmand:

In-Reach:0 >>reload

When the reload is complete, the new software is activated. Log in again.

You can load a default configuration file from a TFTP server while the unit is at its default setting.

Example TTY output:

InReach:0 >en

Upgrading to 5.3.7

Version 5.3.7 only runs on LX platforms with a minimum of 16 MB flash and 128 MB DRAM. It is critical that you do not attempt to load this version on older LX units that do not meet these criteria. All LX-4000T, all LX-8000S, all LX-1004T, and all 7304T are supported.

To determine your flash memory size, enter the show system characteristics and show system status commands. Check the Flash Size and Memory Size fields on the resulting screens to determine space requirements.
