Hello, this is my first post in this amazing forum (i didn´t find the "Newbies say Hi" section), and as usual, i come with questions i hope somebody can answer.
So after being unemployed for 2 years, i´ve landed a miracle job doing Cabling and LAN deployment in a Small Company, basically they are trying to expand to the market of Network Deployments so they needed a "computer guy", wich, you guessed it, turned out to be me.
My very first job, it turns out, is gonna be a big CCTV deployment of a LAN consisting of 20 IP cameras PoE class3. This cameras are going to be installed in different buildings, 2 per building, wich will be connected to a PoE Switch with SFP ports, the backbone of the LAN is a Huge Fiber Optic "ring" that is already there (tough not in use yet). And that will be used to....¿interconnect the Switches?
The Fiber is Multimode 50/125 type Fiber that ends in a Patchcord LC-LC Distribution Box, and the company that hired us is gonna give us 2 threads of the Fiber to work with and deploy the LAN.
When i found out that this was gonna be my very first job, i freaked out !! I was very stressed for a lot of weeks, coupling it with trying to fit in in my New Office and trying to fulfill the desires of the Company (i really need the job, and most importantly i think is a perfect oportunity to learn, otherwise, i don´t see a posibility for a job of this type handling this type of equipment in my near future)
With some self, education, YT videos, and lot of Googling, i´ve been calming down, understanding some concepts and on...so relieving some stress there. This is a huge stretch for me professionaly, i´ve done other jobs before but only with UTP/Ethernet types of medium, never though i had to deal with Fiber; so lately i´ve been learning about Transceivers, miniGBIC, SFP ports, etc. All types of concepts totally new for me.
Heck, i don´t even know how to handle a Managed Switch.
After drawing a Diagram, the questions have begining to rise up once more:
That´s a very rough diagram that i draw, the lines in BLACK are the Fiber Optic cabling, the RED ones are the UTP/STP CAT5 cable that is already wired and tested and go from the Switch to the cameras.
The PoE section of the theory i´ve got it, is in the LAN segmenting and design i´m having troubles with.
As you can see there´s a "Master" Switch with 4 SFP ports that "closes" the Fiber "Ring" and is directly connected with UTP to the Server PC with Ethernet, the rest of the Switches have 2 SFP.
My main questions are:
1) How do i connect the Switches one to another so the NVR software picks up every camera?? Is escalating Switches needed? in this case...what is "escalating" Switches??
2) Do the Switches need to be Layer 2 or 3 ? Is it strictly necessary for the Swithes to have an IP address?
3) Are miniGBIC 1000BASESX SFP Modules enough? We are using LC-LC patchcords
4) Do this miniGBIC modules have to be from the same Brand/Manufacturer of the Switches to secure compatibility
5) How many miniGBIC modules do i need for this LAN (AKA transceivers) ? Can one SFP send AND receive, or are 2 SFP /thus 2 miniGBIC modules/ necessary fot that?
6) Is GIGABIT an ideal Bandwidth for this LAN? Or de we need 10GIGABIT?
And last but not least....
7) Am i gonna lose my job???
Thanks in advance...hope i´ll be the one answering newbies questions soon..
