Updating Firmware

To display current firmware version information

•

Use telnet or a terminal emulator to access the built-in "terminal

interface" and use the ver command to view the version information

for firmware currently in the HP E3472A/73A Emulator.

Though Flash EPROM is very reliable, it can fail. If the HP E3472A/73A

Emulator determines the Flash EPROM is not working, it will try to use the

boot code in its Flash EPROMs. The only useful operation the boot code

allows is running progflash.

Make sure the current version information is incorrect by comparing it

with the version numbers of the update software.

Try updating the firmware again.

If none of these steps solves the problem, contact your local HP

Representative.

If there is a power glitch during a firmware update, some bits may be lost

during the download process, possibly resulting in an HP E3472A/73A

Emulator that will not boot up.

Set switch S4 to OPEN, then cycle power. This tells the HP E3472A/73A

Emulator to ignore everything in the Flash EPROM except the boot code.

Repeat the firmware update process.

Set switch S4 to CLOSED, then cycle power. This restores the

HP E3472A/73A Emulator to its normal mode.
