Reprogramming the Onboard Flash
When necessary, you can use the Recovery Mode UI to reprogram the AastraLink
Pro 160 Onboard flash (firmware) using the procedure described in this section.
Caution: You should only reprogram the Onboard flash with direction from Aastra support
personnel. Incorrect updating of the Onboard flash can make the AastraLink Pro 160 unbootable,
requiring the device to be returned to the factory for repair.
Note: Before you can reprogram the Onboard flash, you must download the obf.dra file (see
below) from the Aastra support web site, and store the file on a TFTP, FTP, or HTTP server that is
accessible to the AastraLink Pro 160 using its LAN connection.
Use the following procedure to reprogram the AastraLink Pro 160 Onboard flash.
