1900 Switch?

Stotic

I was reading the Sybnex CCNA book (4th edition) and it makes reference to configuring a 1900 switch. From what I've read, the 2950 switch is the only relevant switch on the CCNA. Is this true, and should I ignore the 1900 stuff? Also, where do I go to obtain the updated parts of the 5th edition. I can't find it on their website.

Yes, ignore the 1900 switches. Stick with the 2950's for reference.
