Updating CMM Software
1. Extract the contents of the .zip file into a folder (e.g. "C:\CMM\") on the host PC.
2. Open a DOS Command Line Prompt on the Windows* PC and change directory to the above
folder (e.g., C:\CMM).
3. To execute the update, execute the update_cmm.bat on the host with the following options:
a. The MAC address of the connected interface on the CMM is the first command line param-
eter. To find this out, use the command ifconfig eth0 on the CMM CLI to find out the MAC
address of eth0. The MAC address must be with dash separated values (not colon).
b. A second argument “FFS2” must be used when upgrading/downgrading to a different
version. Note that this will reset the passwords, IP addresses and other custom Linux* envi-
ronment settings to factory defaults and clear the event log entries.
Example 3. Example update_cmm command when directly connected or on the same subnet:
update_cmm 00-a0-b7-d8-d8-5d FFS2
c. By default, the update script assumes that the host computer and the CMM are on the network
192.168.100.x. If your host computer is on a different network, provide another command
line argument to the update_cmm batch file. This second argument should be an unused IP
address on the same network the host computer is on followed by the FFS2 argument.
Example 4. Example update-cmm command when connected over a live network.
update_cmm 00-a0-b7-d8-d8-5d 192.168.100.50 FFS2
4. Before pressing “Enter” and executing the command line, reset the CMM by pressing in and
holding the front panel reset button for 5 seconds. The blue hot swap indicator will light to
indicate the CMM will reset. Release the front panel reset button and the CMM will reset.
5. Simultaneously press enter and execute the update_cmm command line.
6. At this point some versions of the update_cmm batch file will prompt if you want to terminate
the batch file. To continue you must enter “no” and press enter.
Note: Due to the nature of TFTP, the timing for the CMM to capture the TFTP request from the update
client can sometimes be missed. This may lead the update_cmm batch file to prompt for the CMM
to be reset again. This is normal and the update will continue as before once the batch file resumes.
Note: Occasionally the batch file will not detect the TFTP timeout, and will bet stuck in one of the update
steps. This is usually indicated by a string of endless dots/periods on the update client screen. If this
happens, hit ctrl-c on the update client, which will prompt to terminate the batch file. At this point
you can hit “y” to terminate the update process and start over, OR to continue the update process,
enter “n”, reset the CMM, and then press enter. The update process will continue from the step
where it got stuck previously.
