Hi, I am trying to make some sense from Chelsio (T540-CR) part numbers (FAB numbers)
In particular:
110-1168-50 C0
110-1178-50 A0
110-1200-50 A0

I cannot find any information on this matter on google.
As I understand this is chip revision?

How I should read it? Greater number newer or vise versa?

Thank you.

Generally speaking, what you say about higher serial numbers, MAC addresses, and revision numbers/letters being newer is correct when comparing samples of the same product. In fact, that is one of my secrets of shopping used hardware online (you are welcome). Part numbers do not change as easily, because they are tied to regulatory approvals (UL, FCC, ETL) and region-specific SKUs.

The Chelsio cards you mentioned should have a manufactured date sticker on the back, unless they are OEM versions. I happen to own two 110-1200-50 cards (mfg 2017) and a 110-1168-50 card (mfg 2014). You can probably guess which are in production and which are in the "sell" pile. It does not necessarily mean an early revision card is "bad".. just that the manufacturer probably worked out any bugs and used better/newer components in the later revision.

Hope that helps!
