How do I determine the OID to get the Serial Number from 1.3.6.1.4.1.11.5.7.5.4 (HP VC Flex-10/10D Module 4.30 )

How do I determine the OID to get the Serial Number from 1.3.6.1.4.1.11.5.7.5.4 (HP VC Flex-10/10D Module 4.30 )  The out of box OID doesn't pull anything. 

I tried several OIDs on this page, but they didn't return anything either:

What is the best way to go about doing this?

Not that either.  That is the OID of the module itself, like the system ID.  I need to extract the serial number from it.  What OID is that? 🙂
