process. Alternatively, the user could go back to the serialization screen to observe the load
running on the WAN card (seen in Figure 9-4 at the beginning of this procedure). Should the
checksum function not pass, then the user will be prompted to try the download action again.
Once the downlaod has completed or failed, then the system will clear the UPGRADE alarm.
XMODEM download process
The user could also select the XMODEM method to update the card. If XMODEM is selected
the screen seen in Figure 5 appears. The capital "C"s appearing in the download screen
indicates that the XMODEM is active. The user must use the terminal communications
package to send the file in XMODEM format. Again, this process will take around an hour to
complete.
After the download has completed, the WAN status, model, version, ID and checksum will
appear. The display will indicate the load that is presently written to flash, which will be the
old load (the one being upgraded from). After the load is transferred, the system will perform
a checksum on the file that has been delivered.
