Rebooting Software
While the system is in an alarm state, do not:
Reboot
Switch to alternate software
Download new software
Unplug the SPU Controller
Reboot
Reboot can be done by
•
Removing and inserting the SPU Controller or
•
Using the Keypad
Alternate Bank
The new software is downloaded into an alternate bank. When the radio is
switched to the alternate bank and if the new software causes a failure within 2
minutes, then the watchdog triggers a reset line and reboots. This algorithm
switches the radio back to the known good software version.
This procedure is a precaution in case the software from the alternate bank is
not stable. See the following example.
