Mike Meyers on: Touring the Network Server Room

welcome to the equipment room for total seminars now in a structured cabling situation like what we have here we have a pretty small network so I have just this one little rack with some equipment on it now first of all this is a 19-inch rack and that's pretty much the standard for all equipment racks now if you take a look behind me you can actually see the blue and white cables that are the horizontal runs coming in for all the devices all over my network now there are two different ways that we can look at the equipment room number one you're going to have what's known as your main distribution frame or MDF in my office this is the main distribution frame you can see behind me there's all kinds of connections to the outside world and this is where it all comes together is right here now in 10 years when total seminars becomes this huge big la palace of training and we have a six story building I'll have equipment racks on every floor and while this one will stay the main distribution frame there'll be other equipment racks on other floors which would act as what we call intermediate distribution frames so make sure you're comfortable with MDF and IDF now there's a lot of different pieces that are on my equipment rack so let's take a look at them starting up at the top okay so starting up at the top of the equipment rack the first thing I want you to notice is my patch panel so the back of that patch panel has 110 punch downs and you can actually see the blue and white cables that are coming from the top and those are all terminated into the back of my patch panel now scrolling down here just a little bit that is cable management folks I don't like my patch cables draped all the way down so I push them into that little area there and it's just a convenient way to keep things a little bit neater now directly below that is my primary switch this is the switch that everybody's connected to on my network and you can tell by all the little lights are a little bit hard to see but you can see them towards the left that this is a very very busy switch directly below that is a router now this router is a developmental router so I haven't really got it up and working right now but you can see there is one piece of ethernet cable going into one end later I'll have it working a little bit better so these are the main pieces of my structured cabling system but what I want you to notice is that there are different heights and these are called use so let's zoom in a little bit onto one side of the equipment rack so that we can understand what a u is now keep in mind that people put all kinds of stuff into these 19-inch equipment racks so we have to have a standardized height the standardized height is called a U and you can actually see they're marked here very very prettily on my equipment rack so 1u right here is an inch and 3/4 so this switch right here is a 1u switch this cable management clump right here is to you so everything that you buy that you put into an equipment rack is going to be measured in use so it'll fit everything uses the same type of screw and they fitted nicely and it allows for a nice uniform look on equipment racks pretty much the only thing left on my equipment rack are my servers total seminars really isn't that big of a company so we don't have racks and racks and servers like you can see at larger companies however we do have a few servers here let me show them to you now starting up at the top I've got two 1u servers I can tell they're 1u because they fit within the 1u marker so there's these two guys they're actually not even turned on right now their developmental I use them when I'm playing around in experimenting we have two servers that do most of the heavy lifting so right here is a server this is a 1u server and we actually call these pizza box servers because as well they kind of look like pizza boxes the reason they slide out like this is for maintenance you see this with a lot of servers today it's very very convenient down here is a 5u server you can actually see it's just five five views it's a big server now this guy is my primary file server he's just got tons of storage and he's actually a desktop system it's tilted over anyway the bottom line is is that this is I've got tons of hard drives in here he works really really hard for a living okay so that's basically what it boils down to in terms of my equipment rack I've got some UPS is at the bottom for power and things like that but that's really what it's all about here now do keep in mind that this is my main distribution frame and as an MDF it has Internet connectivity I would like to show you what I have behind you but before I do that I got ahead you over to the D mark welcome to the D mark for my office building the D mark separates that which is the property of the phone company or the cable company versus what's yours so what we're looking at here is a bunch of equipment that's owned by phone company or cable company whatever it might be now typically the d mark separates the telephone company or cable company's equipment from years but this is a leased building so things are a little bit different here to help explain that let's take a look at this cable connection right here this right here is a it's basically a multiplexer or a splitter that comes from the cable company we've got a great big chunk of coax coming in to the bottom of this and this little splitter is designed to service four different customers now if you're going to be doing cable you need a cable modem so typically in the Demark area we would have a cable modem that would act as our true d mark but because this is a leased office we have offices all over this building everybody has their own piece of equipment so we cannot end the d mark right here we actually have to run this cable over to our office and create a demarc extension welcome back to my equipment room now what we're seeing here is this big cable here on the right is the one that just we saw at the D mark so it's coming down here in my equipment room and it's running down along here yeah they shoved me in here somehow to get this shot and it comes down along it goes through some splitters because we use this for television as well as our internet and this connector right here comes up and connects into my cable modem so we couldn't bring my network to the d mark so we extended the d mark to my network and that's why this box which is not my property is the demarc extension this piece of Ethernet cable right here I own that so this is really where the separation takes place so that's a demarc extension Wow we covered a lot of ground in this episode there's a lot to do when it comes to equipment rooms for the Network+ keep in mind that I want you to remember there's a difference between a main distribution frame and an intermediate distribution frame that equipment racks are 19-inch the height of the U and also keep in mind that you need to know the difference between a D mark and a demarc extension you're going to see all this on the Network+ [Music] you
