Safe Boot
Model 2263 supports field updates of the firmware. Firmware updates are posted on the
2263 web page as they become available. Update procedures are described in Linux and
Windows Software Manuals.
In case the firmware update procedure is unsuccessful for some reason, there is a way to
boot the original firmware (perform a safe boot) and repeat the update. To boot original
firmware press the button located behind the hole in the back panel (using a toothpick,
paper clip or a similar instrument) and plug in the USB cable while the button is
pressed. A red indicator light will turn on in a safe boot mode. After the firmware
upgrade is performed the unit’s power needs to be cycled to force the boot of new
firmware.
