received, the VMSE checks the integrity of the firmware image and then programs the new firmware in the flash ROM. Do not switch off the power supply at this time. A loss of power while reprogramming will result in a corrupt program image and a nonfunctional VMSE.

To load firmware with Hyperterminal, enter monitor mode by resetting the VMSE and type xx1 after the * appears on the screen (you have about 1 second to type xx1).

The 0> prompt tells you that you have entered Monitor mode

Type DL to enter download mode.

Note: you will need to disconnect the Ethernet cable from the VMSE before you do the download.

You must now use the Hyperterminal menu bar and select Transfer… Send Text File. This will give you a dialog box to select the file to download. Select the .hex file for the firmware you want to load. The download will take about five minutes and the hyperterminal will appear dead until the download completes. The figure below shows the results after the download completes successfully.

After a complete reprogramming, the VMSE restarts.

After changing the firmware load in the VMSE, select defaults on the new firmware before setting the configuration to your desired settings; this keeps the VMSE from becoming confused.
