Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality.

Problem Description

In some situations, the insertion of the 15454-M6-ECU or 15454-M6-ECU2 unit in the M6 chassis might require additional force; therefore, the software might not detect the units, because the back-plane connector does not completely engage with the mate that is mounted on the M6 chassis.

Background

Cards that are built between March, 2013 and August, 2013 use a back-plane connector that might require a higher insertion force due to production variability. Once properly inserted, these cards work and behave properly, so no further actions are required. Cards manufactured outside of this time-frame are not impacted by this Field Notice.

Problem Symptom

The insertion of the unit is completed easily up to 2 mm (1/10 of an inch) of the complete seating. From this point, additional force might be required for the proper mating of the back-plane connectors. If this additional force is not applied, the unit does not install properly, and the software does not detect it.

Workaround/Solution

As a workaround, apply more force in order to plug the unit into the chassis. In order to perform a functional sanity check, connect an RJ45 Fast Ethernet cable to the RJ45 port of a PC (not under the same Network IP domain). If the green LED indicator illuminates, the card is correctly plugged-in.

How To Identify Affected Products

The Serial Number Validation Tool, identifies the units that are potentially affected by this problem. If you experience difficulties with the insertion of an ECU unit, insert the serial number of the unit into the tool in order to verify if it is impacted by this problem.

The serial number of the ECU unit is retrieved from the ECU unit itself, or the box from which the unit is shipped.
