EID 1486 Autonomy Mass Storage Drive Not Accessible

Follow this procedure if an event EID 1486 Autonomy Mass Storage Drive Not Accessible occurs. This code is triggered when the system has a reduced write speed to the autonomy logger or if there is no autonomy logger installed on the machine. This code causes no immediate negative issues on the AMT. This code is meant to alert Cat MineStar System controllers of the lack of a hard drive.

Test Step 1. VERIFY AN AUTONOMY LOGGER HAS BEEN INSTALLED ON THE AMT.

1. Visually look in the autonomy cabinet on the platform of the AMT to ensure that the autonomy logger is physically present.

2. Ensure that all connections related to the autonomy logger are secure.

Expected Result:

Hard drive not installed.

Results:

• Hard drive not installed. -

  Repair: Install autonomy logger.

  Proceed to Test Step 4

• Hard drive currently installed. - Proceed to Test Step 2

• Loose connections are discovered. - Proceed to Test Step 2

Test Step 2. CHECK USB CABLE AND CONNECTIONS.

1. Unplug and reinsert USB connection to the hard drive and Auto ECM #5.

2. Visually inspect cable for damage. Replace if necessary.

   1. Verify the connections to the 12-Pin Connector to the Auto ECM #5 J3 location depicted below.

      Note: The J3 location is the top connection on the right side of the Auto ECM .
