Re: Cisco CRS with 100Gb line card

Gotta love it! that's.....around 570KW of power if the legs are balanced (as they should be)! I'd love to see the genset(s) backing up that CO. It's been a while since I've been in any telco buildings.

No kidding! This is a lab, but it's simulating routing for a major metropolitan area/aggregation point. If it was in production, you'd take down a few hundred thousand customers

I would assume that, in production, there would be redundancy, correct?

Although sometimes I assume too much. In my field of work, there are redundancies for nearly everything. Heck, some things even have redundancies for the redundancies. It does get pretty redundant.

The building I work in (which is not a CO, but does house a lot of rather important equipment), has two 1.5MW CAT diesel gensets.

They are MASSIVE gensets and very impressive to see/hear them start up.

Total load is just under 1MW, but there are two gensets for redundancy in case one fails to start.

That's correct. In the production setups, there is a redundant everything (these boxes have redundant processors and power supplies, but on the core network there are redundant routers in case of a chassis failure), including power supplies and cabling into and out of the buildings, HVAC, you name it...

Lightweight...

Largest complex I maintain regularly has 6 1.5 MW and 2 2 MW generators, and I was called in on an emergency to another building of ours with 3 5MW turbines... They are impressive as it gets at startup...

Turbines are certainly the coolest sounding getsets, period. We looked at some but decided against it because there was concern about local service and parts.

Turbines are awesome, but you are absolutely right about service and parts... As well as being tied to a specific vendor - there's 100's of companies that can service your average generator - turbines mean dealing with the company that built it almost exclusively....
