Network pics thread



I know the picture is grainy, sorry for the camera phone pic.

From the top
OpenGear IM4216-2-DDC-X2
Juniper MX80 (Licensed as an MX10), with the 20x1Gig MIC and a 2x10Gig MIC
Juniper EX4500 x 2

The console server, MX80, and 1 of the EX4500s will be shipped to Chicago, which we will have transport from there back to Cedar Falls connecting to the 4500 here.

Stuff below is production ASR1002's which we currently use for edge routing.
 
I have had all the screws out, seems almost like it was a press formed casing? like, it's folded in such a way as to not be opened again.

Probably have to take the face plate off, ive seen some switches slide FORDWARD not back :)

the last dlink i changed fans in for a customer was just that way, you had to flip it on it's top and slide the front forward..


If you can take pictures ill show you..

P.s you might also have to take the rack ears off etc etc..
 
Damn those are sexy. What make and model of fan and mounts?

dashpuppy, more info about those mounts please. I have the fans at home not properly mounted. It's a metal fan and the standard screws don't quite work.

cheap ass fan i got from a friend, the mounts came with the fan ( PERFECT )

they are like this.

For those of you running servers in your own home...how do you deal with the noise? especially if you have a smaller rack with servers/switches/routers in the office and such?

I built a dedicated small room in my basement specifically for my rack, etc. It's the only finished area in my basement, currently, lol, but it certainly keeps the noise under control because one of my vSphere servers is fairly beastly and loud.
 
thats a NOCTUA they are pretty high end for case fans

you can get just the mounts, frozencpu sells them

We removed twice as much coax that wasnt used anymore in late fall in prep for this project(These are right behind the dell racks)

You don't happen to work for IHS or Team Technologies do you?

He must. They are the only ones in these parts that would have equipment like that. Or so I would think.


But I have been proven wrong before. :p
 
The only reason I ask is that I know that is about the only place there that runs some juniper stuff and is even in that town. Unless it's a large business DC. Nice to see people on this forum close to home every now and then

The only thing I can say is that I'm pretty sure that its not UNI but then again I'm not in network ops either so.
 
I'm assuming it's Team Technologies or one of the companies they own as well; only a handful of places in that area I could think of that would have a need for ASR's on the edge.

More pictures and information please. :) I have always been curious and wondrous about antenna towers and the equipment behind them, what they do, etcetera.

Are those /\/\ Quantar's I spy? In a possible SmartNet/SmartZone configuration??? Hmmmmmmm. Hamsexy if they are ;).
 
Started cabling up the new phone system. Don't mind the KVM-IP connectors, they will be going away once it is up and running. Sorry for blurry cell phone pics, I will get some better ones once it is all up and running. 12 servers and 3 Avaya gateways in the MDF, 5 more gateways in other IDF's.

@omegatotal and PigLover, both of you are talking out of your ass.


Really? I'd love to see your data to backup that claim.


Seriously? Any data center worth calling itself a datacenter feeds 60Hz conditioned sine wave power to the data floor. It has been fed through either generators (flywheel or other) but ideally UPS batteries with line conditioners before it even reaches your equipment.
Saying a lighting striking a data center building and it somehow bypassing the building grounds, going into the buildings electrical system, bypassing the generators and/or UPS conditioning, bypassing the 3phase 480v load centers feeding the rack rows, bypassing the rack/frame ground and going directly into your equipment is a very foolish statement.

I've had equipment in 2 different data centers in Phoenix Arizona one of the driest places in the southwest. Lightning strike alley especially during the Monsoon season. If I would ask any of the facility managers at those data centers if I should ground every single piece of my equipment because a lighting strike would make it to my switch they would laugh at me. Rightly so.

why do you think they include ground points like this anyway.. they are there for a reason, yes they may not be needed in every single possible circumstance and you may get by with sheer luck.. but i have had my share of pre-mature hardware death due to un-explainable random grounding failure..

also just food for thought, i like to keep everything i own in major brand mid range or better UPS hardware and i understand how a lot of data centers have power systems, from physical inertial ups' like the spinning disc you speak of, to high quality ac to dc systems with dc to dc converters instead of running ac->dc->ac->dc which just makes more heat...

have i seen them all, no definately not, have i been involved in setting any of them up, nope, but i do have an understanding of the principles involved..



I would, too. Why wouldn't the grounding to the chassis from the mains be enough? Is it your assertion that the ground line in the mains connection isn't tied to the chassis? Are the devices you're using not CE or UL approved?

i bet you have never had a power cable fail to maintain a good earth ground... and then cause random network ports to randomly drop sync. all because you wanted to keep your rack looking clean and your equipment looking like new, so you used black anodized screws with black nylon washers to mount your switch in your rack that has painted/powder coated rails. so suddenly your switch became un-grounded and started to act all derpy...

guess what? a bare wire on a designated grounding post on the exterior of the equipment mounted in that pretty boy rack just made all that other shit irrelevant and it took a few extra bucks and 10 minutes max per device to hook up on the initial setup...

fucking tards
 
Nice radio stuff. I am guessing it's all P25?

beats me....I do not know much about the radio stuff, I just have to play nice with it....
More pictures and information please. :) I have always been curious and wondrous about antenna towers and the equipment behind them, what they do, etcetera.

wish I could, I dont know much about it, and I probably cant throw out tons of info.

I work for a county wide 911 dispatching center and this is our main tower attached to our center. we have 5 other towers through the county and I have a 4mb microwave loop to them. sadly the jump to about 11mbs is extremely costly. but I should have fiber thanks to a community big broadband project to the 3 of the other towers, one which is attached to our future backup site


Are those /\/\ Quantar's I spy? In a possible SmartNet/SmartZone configuration??? Hmmmmmmm. Hamsexy if they are ;).

I DO know thats the HAM stuff, we just tore alot of REALYL OLD ham stuff out that from circa like 1970's

I would, too. Why wouldn't the grounding to the chassis from the mains be enough? Is it your assertion that the ground line in the mains connection isn't tied to the chassis? Are the devices you're using not CE or UL approved?
I would have to double check but I can't imagine that just about everything HP sells is CE/UL Listed/approved

take it up with Motorola if you think its so bonkers :p

yeah you cant trust the 'mounting it to the rack' as a ground, everything is painted, hell even some of the cage nuts I have came painted black, most of the mounting ears did, and the racks obviously are. it mounted to a grounded rack is def NOT a good reason not to do it

I am NOT AN EXPERT, just learning some of it as I go from the motorola cert'd radio guy in the office

How interesting! I didn't know that Motorola installed the external chassis grounding leads on your HP switches. Do you know why they did that?

You are an idiot. Go troll Gen May.

LOL. What did I miss? The switch chassis are grounded through their plug to the mains. They're not subject to RF energy, and also not at risk from energy dissipated from a lightning strike. Why, then, the concern over additional low impedance bonding? If "pre-mature hardware death due to un-explainable random grounding failure.. " is really random and unexplainable, then how do we know it's the cause of the premature death?

Really, if you read back through the thread, we haven't heard any reasoning for these flimsy grounding connectors. No viable explanation, no engineering -- just lots of arguing and naive rationale like "it can't hurt". It can hurt; grounding the same equipment to two different grounding points at different potentials is a problem. If you want to call digging for a better answer "trolling", then go ahead. But it might be more prudent to let the adults have their discussion.

Nope, IHS will be part of the Chicago connectivity for transport. I work for CFU.

Wow, I've seen lots of your posts and never suspected you were in Iowa.

This is the first Juniper gear for CFU so I'm not surprised you didn't suspect us.

It doesn't even matter about the technical aspect anymore. You and cyr0n_k0r have been completely belligerent towards haunter. If you want to troll, go to Gen May where it is accepted. Your bickering about how it is unnecessary wire adds no value to this thread not to mention being completely off topic.

Get over yourselfs and post something useful.

Mike, this probably isn't the right forum to educate you on the difference between system ground, frame/chassis ground and earthing. Its is probably also not the right place to describe the changes to the earthing system that happens during a lightning strike or how improper grounding can change the float of your system ground in a way that actually induces dangerous current potentials between system ground and earth, or why it is important to maintain a traceable earth ground path from each piece of equipment - with a single traceable tie-in between earthing and system ground. And it actually has little to do with the fact that there are RF cables entering the particular building being discussed (though it probably does have to do with the fact that there is a 200+ foot metal tower effectively attached to the building increasing the likelihood of a strike). These principles apply equally to any equipment system with or without "RF cables" entering the building.

Believe me - there is a hell of a lot of engineering behind the need for proper grounding. Its a lot more complicated than making sure your power cable has a ground lead. That you don't understand it is really not a good reason for you to attack people who choose to follow their manufacturer's recommended grounding procedures.

Your right I would have never suspected you guys. My first thoughts were IHS / FUG, with their Health Net Connect. I know a couple of guys on there and it seems like there is bandwidth issues more often than not. When the service started up a few years ago, I talked with some of the guys what the core of the network looked like and they talked about Juniper M series, and they were using J series at the customer edge. Good Times.
 
Mike, this probably isn't the right forum to educate you on the difference between system ground, frame/chassis ground and earthing.
The responses I've gotten to my questions make that completely clear. Sometimes, I get lucky -- I ask a question and someone who can understand the question and is articulate enough to answer it responds. That makes it worth trying. In this case, cymon came pretty close to giving a good answer, but I don't think I've yet hit paydirt.

Sometimes there is, and sometimes there isn't. So far, for this installation, we haven't seen any evidence of it. If the answer is just "I don't know" or "we did it at the recommendation of the vendor's installer", then that's fine. Posing and bickering is very different than sharing knowledge.

1. why the hell are you all arguing here about grounding? go start your own topic for this. its getting annoying.

2. you all suck.

3. Moar network porn!!!!

Installed a PTP link using a pair of Ubiquti Loco M5s to bring in another FiOS line from our other property.

This is the end point mounted on my shed. Commence the "you did it wrong" below, because I probably did. Works great tho, pushing like 75/75 over the bonded links.

I don't think it looks bad. I do dig the sat dish mount that your re-purposing.
 
Looks good to me, as long as it works. Job well done :D

Mike, that looks like a very comfortable space :D

The person who posted from this site gave what may be the best answer possible: his equipment provider required the ground leads to maintain warrenty. I'm going to go out on a limb here and suggest he probably wasn't the power/grounding engineer responsible for designing this installation - so I don't know why you would expect to get an answer better than that one.

And re-read your posts. They do appear to be quite hostile and derisive. You might not have intended that - but they are.

I apologize for the crappy picture. Did a bunch of cleaning up today and reorganizing. (Nothing is hooked up or on because of cleaning up.) This is the start of my Cisco lab. 2 x 2950s and 2 x 2611s. Using them for my ICND1 test in a week and a half. On top is a Routerboard 450. I have an ASA 5505 and a 881 on the way to play with as well. Will post pics.
 
the Ubiquiti devices, the wife's mothers house is about.... 100m away, have a row of houses between us and the houses are concrete with tin roofs, i wanted to do a site to site link for her to get internet from us, since she barely uses anything but the cheapest Inet here is $30 a month and she always has problems with them.

would any of the sub $100 devices for for a site to site, can mount them our our roof and her roof on a pole sort of things i was thinking?

 
With something like that MrGuvernment I would go with nanostation or nanobridge Yes I am a WISP and use Ubiquiti devices.

Make sure both devices are up in the air at lease 30-40ft so they can have clear LOS.
 
appreciated, will check those out, luckily the houses are all single story places between us.
 
Had to change out some bad ram on a Cisco UCS blade tonight that has been throwing errors all week. Gotta love late night maintenance. That is what 196GB of ram looks like :D Fingers crossed that it does not happen to my other blades.

That's interesting
48 ram slots, so you only need 4gb sticks to get 196gb ram..... Noice

What dimm size max does it take?
