Q Are there any visual differentiators between the E-Series line cards and the classic line cards?
A Yes, of course. The E-Series line cards will have a subtle cross-hatch pattern and a yellow circle on the right end tab, visually identifying them as E-Series line cards. This will be useful in a mixed E-Series/classic line-card configuration.
Q Is local switching supported on the E-Series line cards?
A No. It is not supported on the Cisco 4500-E line cards.
Q Are the E-Series line cards supported in non-E-Series chassis?
A No. The classic Cisco Catalyst 4000 and 4500 chassis maximum per slot capacity is 6 gigabits per slot.
