[c-nsp] Catalyst 4500 E-Series

[Antonio Soares]

I'm trying to understand the differences between the WS-C4507-E and the
WS-C4507+E but I'm confused:

1) 4503-E, 4506-E, 4507R+E, and 4510R+E chassis are extremely flexible and
support either 6 Gbps, 24 Gbps, or 48Gbps per line-card slot. 4507R-E and
4510R-E chassis are limited to 6 Gbps and 24 Gbps per line-card slot.

-> So the +E seems better.

2) Part Number Max Rated Power (W) Rated MTBF (Hours)

WS-C4507R+E 135 248,630
WS-C4507R-E 135 365,896

-> Now the -E seems better

3)

WS-C4507R-E 10K GPL
WS-C4507R+E 7K GPL

The +E looks much better :)

What is the logic behind all this ?
