Force PROM Mode
There may be circumstances when the control firmware, located in Flash
memory, could be made incompatible with Switch operation (for example,
through a failed Flash load operation) and yet the Flash Check Sum could be
correct. If the Switch attempts to operate with the incompatible Flash Code, it
could lock up and not allow a new Flash Burn operation.
Refer to Figure C-3. The Force PROM Mode switch causes the Switch to operate
with control code stored in its PROM, and await the loading of new Flash code.
Refer to the Diagnostics/Troubleshooting Section for how to load new Flash
code.
The Force PROM Mode switch must be in the OFF position for normal Switch
operation.
