To download the new software, use the arrow key to move over to the 'dnload' option. The user
will be presented with a question: "Are you sure you want to overwrite this block (y/n)?".
Select 'y' to confirm the process. New in release 6.1.2, after the user confirms that the
download is desired, the system will raise an UPGRADE alarm, noting the WAN card being
upgraded. The user will then be presented with the option to use XMODEM or TFTP. The
XMODEM option is supported only via a direct connection to the IMACS unit. Should the
customer attempt to use the XMODEM option on a telnet session, the IMACS will respond
with "Error, a modem connection is needed to start the XMODEM transfer…".In this case,
you must choose the TFTP option. The upgrade will take approximately three minutes,
depending on latency in the network. The user must have a TFTP server set up in order to
choose the TFTP process. If the user chooses an option they wish to change, simply hit cntl-x
to abort the loading function.
TFTP download process
Once TFTP has been chosen, the user will be presented a series of questions. Use the defaults
when prompted. Following are the questions and the correct way to initiate the download:
Mismatch retries: Hit carriage return to select the default value of 20.
Timeout retries: Hit carriage return to select the default value of 4.
IP Address of server: Enter the IP address for the TFTP server which is pointing to the location
for the new WAN load.
