Network Devices and Connections

• Types of Connections:
  • Copper straight-through
  • Copper cross-over
  • Fiber connections (no differentiation between single-mode and multimode in Packet Tracer)

Cabling and Connections

Device Connections

1. PC to Switch Connections:

   • Use straight-through cables for connections as PCs and switches have opposite transmit and receive pin configurations.
   • Connections:
     • PC1 to SW3
     • PC2 to SW4
     • PC3 to SW7
     • SRV1 to SW8

2. Switch to Switch Connections:

   • Use cross-over cables for connections as devices are of the same type.
   • Connections:
     • SW3 to SW1
     • SW1 to SW2
     • SW4 to SW2
     • SW7 to SW5
     • SW5 to SW6
     • SW8 to SW6

3. Router to Switch Connections:

   • Use straight-through cables since routers transmit on the same pins as PCs.
   • Connections:
     • SW1 to R2
     • SW2 to R2
     • SW5 to R4
     • SW6 to R4

4. Router to Router Connections:

   • Cross-over cables for copper connections due to same device type.
   • Evaluate distance for cable type:
     • R2 to R1: Use a crossover cable (50 meters apart).
     • R1 to R3: Use single-mode fiber (3 kilometers apart).
     • R3 to R4: Use multimode fiber (250 meters apart).

Summary

• All devices connected using appropriate cable types and connections.
• Packet Tracer visual symbols used for fiber optic connections.
