What does Default instrumentation mean for Card-Fault in Smarts IP Manager?

Smarts IP Manager Device certification has Card-Fault = Default in instrumentation section
Smarts IP Manager Device Certification contains the following:

INSTRUMENTATION:
Card-Fault = Default

Environment

VMware Smart Assurance - SMARTS

Resolution

The Default card-fault instrumentation was introduced in Smarts IP Manager mainly because the OldCiscoChassis MIB was deprecated by Cisco. In previous versions of Smarts IP, every symptom for Card Down notifications required that the InstrumentedBy relationship was populated for that particular card. Therefore, if you had a Card without instrumentation objects, it could never fail. For example, if a Cisco device was certified to use the OldCiscoChassis MIB for Card-Fault, and then the device's IOS was upgraded so the OldCiscoChassis MIB was no longer supported, the Card Down notification would never be generated.

The Default card-fault instrumentation allows the Smarts IP codebook to decide if the Card om such a situation might be Down as follows: 

• Card Down will be triggered based on the status of Network Adapters (Ports and Interfaces) that forms the "Realizes" relationship set for the Card.
• This instrumentation object enables multiple NetworkAdapter failures to gravitate to the Card and generate a card down notification.
• If one or more NetworkAdapters have a valid status, Card Down notification will not be generated.

The code analysis will prohibit a Card from being a candidate for the RCA if one or more NetworkAdapters have a valid status. These "valid" statuses are:

• UP
• DISABLED
• OTHER
• UNKNOWN
• DORMANT
• TESTING

Any other status reported will be counted as if the card is "DOWN".
