1. Kya-Kya Chahiye?
- CAT5e ya CAT6 Ethernet cable
- RJ45 connectors
- RJ45 crimping tool
- Cable tester
- Cable cutter/stripper
2. T568B RJ45 Color Code
Connector ko saamne se dekhte hue contacts ko Pin 1 se Pin 8 order mein arrange karein:
| Pin | Wire | Color |
|---|---|---|
| 1 | White-Orange | |
| 2 | Orange | |
| 3 | White-Green | |
| 4 | Blue | |

3. LAN Cable Banane Ke Steps
Step 1 — Cable Strip Karein
Outer jacket ko carefully 2–3 cm remove karein. Andar ke conductors ko cut na karein.
Step 2 — Wires Straight Karein
8 wires ko separate karke gently straight karein.
Step 3 — T568B Order
Pin 1–8 ke according White-Orange se Brown tak order set karein.
Step 4 — Same Length Cut
Sab wires ke ends ko ek straight line mein cut karein.
Step 5 — RJ45 Mein Insert
Color order check karke wires ko connector mein poori tarah insert karein.
Step 6 — Crimp
Connector ko crimping tool mein rakhkar firmly press karein.
4. Doosre End Par Kya Karein?
T568B
T568B
Isse standard straight-through cable banti hai.
5. Cable Tester Se Check Karein
Crimping ke baad dono ends ko cable tester mein lagayein. Tester par pins 1 se 8 correct sequence mein show honi chahiye.
6. Straight-Through vs Crossover
| Type | End 1 | End 2 |
|---|---|---|
| Straight-through | T568B | T568B |
| Crossover | T568A | T568B |
Modern network equipment mein Auto-MDI/MDI-X support common hai, isliye normal PC-to-router/switch connection ke liye straight-through cable generally practical choice hai.
7. Common Problems
| Problem | Check Karein |
|---|---|
| LAN detect nahi ho rahi | RJ45 crimp aur cable tester |
| Wrong tester sequence | T568B color order |
| Connection baar-baar toot raha hai | Loose/damaged connector or cable |
| Internet nahi chal raha | Router/switch port aur network adapter |
