It is very stable and has plenty of cable management options. They are kind of a cross between a two post and a cabinet. Basicaly the side cannel is 16.25 inces deep. Unfortunatly, the 6500 has slot spacing that doesn't line up with rack U's so most cable management will not work perfectly. The Might Mo can handle the density but make sure you use the largest vertical channels you have room for. You probably are not interested in doors but in locations where this is desired, the doors over the vertical channels hinge both wasy and remove easier than anything I've seen. You probably want to look at the air baffles since the 6509/6513 have right to left airflow rather than front to back. One fo the features in the Mighty Mo 10 is the ventilated side channels and available baffles. The airflow can actualy be one of your biggest challenges if you have 6509/6513's in adjacent cabinets. The warm air from one can blow into the input of the switch to the left. You could also look at using the WS-C6509-V-E chassis with front to back airflow and built in cable management.

async serial fiber transceivers
by Christopher O'Brien 22 Sep '10

22 Sep '10

Greetings, I am planning on deploying a console access server on my network for 20-30 network devices including routers, wireless controllers and other devices. The design is to have one central device for all console access. Due to the geographic diversity of my campus, I will need need to carry the async serial connections over my fiber plant with long reach optics and single mode fiber. I have the fiber plant to support this design. I have been researching solutions to implement the serial part, but I am not very familiar with the vendors I am coming up with. For instance, I know Black Box Networks makes products like this but they only seem to have stand alone devices. I was hoping for something rack mountable since I will have a dense deployment of these devices. Does anyone have experience deploying a solution like this or with async serial fiber transceivers in general? I welcome any suggestions. -Chris

US hunters shoot down Google fibre
by Eugen Leitl 21 Sep '10

21 Sep '10

http://www.itnews.com.au/News/232831,us-hunters-shoot-down-google-fibre.aspx Repairers forced to ski in to Oregon back woods. Google has revealed that aerial fibre links to its data centre in Oregon were "regularly" shot down by hunters, forcing the company to put its cables underground. The search and advertising giant's network engineering manager Vijay Gill told the AusNOG conference in Sydney last week that people were trying to hit insulators on electricity distribution poles. The poles also hosted aerially-deployed fibre connected to Google's $US600 million ($A635 million) data centre in the Dalles, a small city on the Columbia River in the US state of Oregon. "What people do for sport or because they're bored, they try to shoot at the insulators," Gill said. "I have yet to see them actually hit the insulator, but they regularly shoot down the fibre. "Every November when hunting season starts invariably we know that the fibre will be shot down, so much so that we are now building an underground path [for it]." Gill said that on one occasion, a snowstorm and avalanche prevented Google from transporting repairers and gear into the area of the cut. It usually used a helicopter or a Caterpillar D9 tractor for transport. It improvised by sending three technicians on skis to "repair the fibre that got shot down". "These guys had to cross country ski for three days," Gill said. "[One guy] is carrying what is known as a fusion splicing kit on his backpack." He joked: "These guys had to go in and fix the fibre while facing gunshots "So [the] internet... [it's] more dangerous than you realise."

Every winter we had at least 4 shotgun-blast outages, sometimes in the middle of nowhere and sometimes with a direct line of site to the back porch of a local "manufactured home". You would be amazed at what people find fun with during a long, cold winter and a belly full of libations. And I can almost guarantee you it wasn't sabotage. In many cases, the revelers were shooting at power lines and happened to hit the fibers wrapped around the ground wire. These are 500 kV lines by the way. Long story short, you can't account for stupid. Mike -- Michael K.

In my experience, there's really two types of shootings (which really depend on the region) -- Number one is using shotguns, not rifles, and bird hunting - for example when goose hunting season happens, you'll see fiber shot out over lakes/rivers more often - I think this is both bad aim and not really caring. (Occasionally the shot will even be stuck in the lines or insulation so you can tell it was a shotgun) The second is drunk idiots shooting at the lines - this is more universal and happens closer to civilization. Power companies will also have repair issues with either of these, but fiber, phone, and cable lines are more likely as they are lower to the ground due to regulations that state they have to be at least X feet away from the power lines. I don't think anyone is claiming all hunters/gun owners are irresponsible, but, as with any segment of the population, when you have a large group there will be a percentage of complete idiots out there who take stupid actions. As for the 2nd amendment stuff - I'm not touching that one with a 10 foot fiber ;) Leslie

Several years ago I heard of a Swiss ISP having the same problem. They built their network by running fibre along the earth conductor of high voltage transmission lines (like Energis in the UK). I was told that it was common for hunters to verify the setting of their sights by shooting at the lines.

Do any of our fellow nanog members have experience with cable management on 6509/6513 cisco switches? We're upgrading infrastructure in some of our facilities,.. and until it came to cable management, the switches seemed to be a great idea... 8 48port blades.. pose a challenge.. or a problem.. Pictures are welcomed... off-list contact would be great. Thanks

So it is my intent that this be my first, last, and only post on this topic. Was it addressed at NANOG (in SF?) that many rifles and amateur shooters both, are capable of sub-MOA accuracy at short distances? By short, I mean ~50 yards or less. Or that a hunter with even modest self-training, who was aiming at an insulator with a properly sighted-in rifle at short range, has a significantly greater probability of hitting the insulator being aimed at than of hitting the supported wire? That wasn't addressed in the buttwipe propaganda from down under. Need I remind anyone of the Dunblane and Port Arthur incidents and the subsequent gun control crackdowns in each of those countries. I wouldn't expect any crown- influenced news agency to give issues involving our Second Amendment a fair shake. Just like I don't expect logic or sanity from the Brady Campaign on the 2A issue. Nor should anyone else. The story smacks of deliberately painting hunters as irresponsible ruffians and worse. What sort of repair rates do the power or other companies running wire across that expanse contend with? Given the remoteness, the identity of the affected client (Google) and the apparent absence of additional information, corporate sabotage seems just-as or even-more probable than random irresponsible hunters. To be fair, some shooters are irresponsible, but deliberate sabotage cannot be ruled out with only the information currently available. Reese
