If you want to establish a LAN Network in any office, you must survey the premises. You have to know how many user in the office. According to user your have to calculate all devices
Total Node (User) – 100
1. Switch 24 port (Unmanaged) – 5 units
Switch Depends on the nodes. If nodes are 5 then 8 port switch 1 unit. if node is 8 then we must use 16 port switch due to 1 or 2 uplink port(s).
If 100 nodes are distributed from one rack then we need five 24 port switch
On the other hand if the 35 nodes in one side of the building and 65 nodes in another side then we can use two racks. one for 35 another for 65. Switch calculation will be for 35 nodes 24 port switch 2 units or one 24 ports and one 16 ports
For 65 nodes - three 24 port switch
2. Patch Panel (24 port) - 5 Units
Depends on the number of 16 ports or above ports switch.
3. Wire Manager 1U – 5 units
Depends on the number of patch Panel
4. Patch cord 1 Meter (colored) - 100 Units
Depends on the number of Nodes. Uses: in the rack for patch panel to switch connection
5. Patch cord 3 Meter (colored) – 100`Units
Depends on the number of Nodes. Uses in the end user
6. Face Plate – (Single Port) - 100 Units
Depends on the number of Nodes. Uses in the end user
7. Modular - 100 Units
Depends on the number of Face Plate. Uses in Face plate
On the Other hand if the Faceplate is dual port then the modular should be double than Face Plate
8. MK Box/Back Box Sunrise/Local - 100 Units
Depends on the number of Face Plate. Uses for the back of Face plate.
If you need to console wall then you must use metal MK box. Otherwise all Plastic
9. Rack 24U close – 1 unit
Rack size depends on the number of Switch, Patch Panel and Wire Manager. Here Switch -5 units, Patch Panel - 5 units, Wire Manager - 5 units. Total 15. And all are 1U size. So we need 15U. Each U have 3 hole in rack. 1 hole will be wastage between two devices. So here 15 hole will be wastage means 5U wastage. So total need 20U. That's Why we gave here 24U rack. Client can keep something more. In that case we have to calculate that.
10. UTP Cat-6 – 3000 meters / 10 boxes (at actual)
From Switch to Face Plate you have to calculate cable length physically. Don't exceed 100 meters. If so in that case we have to go for Fiber connection
11. RJ 45 connector – 10 units
we can use it both end of the cable. Though we are using Patch Panel one side and Face Plate on the other side. So we don't need any connector. But sometimes it requires for uplink cable or others. That's why keep this always 10 or more.
N.B: PVC Channel, GI pipe, PVC Pipe, T-joiner, Bend, Flexible Pipe, Royal Plug, Screw, GI Wire, Electric Tape, Cable Tie Etc. - As Required
These Items also required for LAN installation. Calculate as an assumption.
LAN Connection:
Basic Connection: Switch -> UTP Cable with connector both end -> PC
Proper Way Connection: Switch -> Patch Cord 1 meter -> Patch Panel -> UTP cable -> Modular in Faceplate & MK box -> Patch Cord 3 meter -> PC
