It would help if you actually posted something. Thanks for nothing, now i'm going to have to get my network p0rn fix somewhere else edit: ah, thats better! |

Sorry about that! They uploaded sideways, so I deleted and re-uploaded to avoid any serious neck strain. |

Snippy snip snip and something major goes down. Probably cost a pretty penny. |
|
|
25KW? sure, why not. | A fair amount of 4GA cabling. |
How do you power it? Generously (albeit this power draw is for several CRS, and a few ASR9Ks as well) |

Transfer switch at a CO... 395A... on a single phase of the 480V-3ph feed into the building. |
|
|
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. |

This is awesome. I was curious so I pulled some pricing...
The Cisco 1X100GBE card is $110,000 and the 100GBE CFP LR4 module is $56,000 |

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. said by cablegeek01:I'd love to see the genset(s) backing up that CO. 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... |

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... |

That's good to know! Our DC plant guy is rather old school and shies away from the computer aspect of things. I'll get a hold of Argus/Alpha and get the new load. It's running the 3.6KW rectifier modules, and we're pretty close to capacity (had to move some gear off of it earlier this month). I didn't know they had a 4KW option; time to read up! |

As a heads up - you'll have to update in steps; you can't go from 1.95 to 2.05 in one jump...
There are some pretty big upgrades in 2.04, it's the load I run on most of my sites... But I do a lot of snmp and remote access - in a lab, with physical access, it may not be as big a deal.
And yes, there's a high effiency 4kw module, plug compatible with the 3.6... |

Thanks! |

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. |

Couldn't possibly convince you to get a private 10/100/1000 RJ45 connection into that 100G line, could I cablegeek01? Regards |

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.... |

How many people run through that thing ?. That thing has to be good for at least 180,000+ residential subscribers. |

Toss in a bit of over-subscription, and he should be able to offer 512bit/s and 1kb/s service! That should easily be enough to put the last of the morse code operators out of work (phfft, 55 bit/s is the best they can muster). |

You would be surprised how little bandwidth most of people use. edit: that number was assuming a 5 megabit plan and I may have accidentally moved a decimal place. |

Those tight bends at the fiber connectors can sometimes be a problem. However I would love to get ahold of a small portion of that BW. |

Correct me if I am wrong, but those look like SC connectors on that fiber... Does that thing really only require 2 fibers to push 100G? I was under the impression that 100G used a total of 20 fibers for 10x 10G channels and typically used 2 ribbons of fiber with MTP connectors.
I've never seen anything of this magnitude though. Fastest I've worked with is 10G. |

Back when 100G came out that was true, but it hasn't been the case with the advent of WDM and DWDM technology (pioneered I believe, with 40G ethernet). |

That's still true for "SR" (multimode fiber), but who's going to do 100G on MM???
(It's more likely to use the SR optic to make a single 100G interface 10x10G interfaces.) |
