Update firmware and Boot/POST Code
The firmware and/or boot/POST code for a Digi device can be updated from a file on a PC
or through TFTP.The recommended method is to download the firmware to a local hard
drive. TFTP is supported for those using UNIX systems. Both the firmware and the boot/
POST code are updated using the same set of steps. The Digi device automatically
determines the type of image being uploaded. Before uploading the firmware or the boot/
POST code, it is very important to read the Release Notes supplied with the firmware to
check if the boot/POST code must be updated before updating the firmware.
Prerequisites
These procedures assume that:
 A firmware file has already been downloaded the firmware file from the Digi
web site.
 If using TFTP, that TFTP is running.
