UPGRADING THE GXP2200EXT

The GXP2200EXT uses different number to identify the firmware version from GXP2200. However, the

firmware image is built in with the GXP2200 and there is no separate firmware file to be downloaded for

GXP2200EXT.

To upgrade the GXP2200EXT, install and connect the GXP2200EXT to the GXP2200 (make sure

GXP2200 is booted up successfully). When the connected GXP2200EXT boots up, it will retrieve firmware

image from the host GXP2200 and start upgrading process if new firmware image is presented.
