[c-nsp] Mystery Cisco device

[Eric Andrews]

Hey, just saw something interesting...

It's a 1U Cisco device, two XENPAKs on the right and 24 SFP ports in
groups of 8 on the left. Console and aux ports on the front, and two
removable AC power supplies in the back. I couldn't see the model
number on the front, but it ends in "10GE". It says WS-4991 on the
back, but Google doesn't know anything about that.

Anyone know what this beast is?
