What are the new features of 4500E in compare to the classic 4500?

and what that E stands for?

and we have quite few other combinations as well

4507R, 4506-E, 4507R-E, 4507R+E

I know what that 4th digit is, but I don't know about those letters especially when they are subtract and add signs?

Thanks

I recall (?) the "E" is for enhanced.

One major enhancement is the newer chassis support higher bandwidth per slot. The original (i.e. non E) chassis only supported 6 Gbps per slot while the later models support 24 or 48 Gbps per slot. (Some of the -E models, the 4507R-E and the 4510R-E only supported 24 Gbps per slot, but the latter 4507R+E and the 4510R+E support 48 Gbps. [Yea this is confusing as the 4503-E and 4506-E support 48 Gbps, likely the redundancy or extra slots of the 07R and 10R models impacts the fabric.])

I'm not 100% positive but the later chassis might support higher wattage power supplies too (to support the later PoE ports that can provide more than 15W per port).
