Hello,
The 50M part number is a manufacturing #. Try searching on this: 76000218
Or you can find the additional concentrator at this link:

Will that be able to connect to the old hub?

Yes, they can be daisy chained together to add more ports.

Thanks, I was worried since the picture of the new units looks different then the old units.

It may have a different faceplate or something, but the functionality is the same.
