While an SSI device that is blinking a “Bootloader status” error code is bricked and must be replaced, that is not necessarily true of nLight devices. Using SensorView to attempt a firmware update to the device may result in good success.
Example with an nPP16: Intentionally disconnecting the Cat5 cable in the middle of a firmware update resulted in the SensorView message below.
MOVE AWAY FROM THE UPDATES TAB AND THEN BACK TO IT, WE SEE THE DEVICE SHOWING THIS STATUS
Meanwhile the LED’s of the device itself are blinking as seen in the attached video (not a slow-steady blink in this case).
Proceed with another attempt at updating the device firmware and observe if firmware update process this time completes with success.
If the subsequent attempt(s) at updating firmware fail(s), then consider troubleshooting the Zone(s) the devices are in. If the databus on a daisy-chain of Cat5 cable is noisy or has frequent corrupt messages, that condition may prevent successful firmware updates. Troubleshoot the Cat 5 with Bus-Splitting similar to what is done when there are comm errors.
