I have questions about DASIY CHAIN and VKNG

Hi, I have questions.

First,

The number of daisy chain.

When I make a vmax quote, if I add DAE, then there is a VMAX VG DAISY CHAIN 3 METER UPG.

And its quantity is 1.

I  checked it through "Display Material BOM" to know its real  amount, and it also said its quantity is 1.

However, I don't think it's not just one DAISY CHAIN. As I know VMAX DAE needs more than one DAISY CHAIN.

How many Daisy chains do I get when order VMAX VG DAISY CHAIN 3 METER FD UPG(E-DCH3MCBLUF)

Second,

the meaning of VKNG.

I think "Model : VKNG" means that 120 Drive DAE code name, Viking.

is it right?

However below picture is a engine. Is VKNG another model?

Thank you
