19 Slow Red Blinks on SNAP-PAC-S2


Applies To:

SNAP-PAC-S1
SNAP-PAC-S1-FM
SNAP-PAC-S1-W
SNAP-PAC-S2
SNAP-PAC-S2-W

Versions Affected:

Problem affects versions: R8.2 and lower


Symptoms:

If you download firmware R8.2 or lower to a SNAP PAC S-series controller with a microSD slot, the STAT LED shows 19 slow red blinks (serial port 2 failure code).

Workaround:

Use firmware version R8.3 or higher on a SNAP PAC S-series controller. To install new firmware:

  1. Using an Ethernet crossover cable, connect the computer you will use for updating firmware directly to the PAC's ENET1 network connector.
  2. Press the controller's Reset button and wait while the STAT LED turns solid green. Release the button as soon as the LED starts to blink (takes 2-5 seconds). The LED will rapidly blink red/green, indicating that the controller is in loader mode.
  3. Follow instructions in the PAC Manager User's Guide (form 1704) to Install Firmware via Failsafe Bootloader Mode.

Resolution:
