🖥️ CompTIA A+ Lab 5.2.8 — Connect Computers with a Switch This lab demonstrates how to connect multiple computers to a network switch to enable LAN communication and internet access in a small network environment. ________________________________________ 🧠 Key Concepts Switch Overview: • A network switch connects multiple devices on the same local area network (LAN). • Operates at Layer 2 (Data Link Layer), forwarding frames based on MAC addresses. • Supports full-duplex communication, VLANs, and port management. CompTIA Exam Tip: Understand the difference between switch vs hub, straight-through vs crossover cables, and basic troubleshooting steps for connectivity issues. ________________________________________ ▶️ Step 1 — Prepare the Network Devices • Ensure all computers and the switch are powered off before connecting. • Verify Ethernet cables (Cat5e, Cat6) are in good condition. ________________________________________ ▶️ Step 2 — Connect Computers to the Switch • Use straight-through Ethernet cables to connect each computer’s NIC to a switch port. • If connecting two switches together, use a crossover cable (modern switches often auto-sense). ________________________________________ ▶️ Step 3 — Power On Devices • Power on the switch first. • Then power on computers one at a time. • Observe link lights on the switch to confirm physical connectivity. ________________________________________ ▶️ Step 4 — Configure IP Settings • Assign IP addresses manually or via DHCP. • Verify all devices are on the same subnet for LAN communication. ________________________________________ ▶️ Step 5 — Test Network Connectivity • Use ping to test communication between computers: ping IP_Address_of_other_computer • Confirm internet connectivity if the switch is connected to a router. • Test file sharing or other network services as needed. ________________________________________ ▶️ Step 6 — Verify Switch Operation • Check switch port activity lights to ensure data is being transmitted. • Optionally, use switch management interface to view MAC address table and port status. ________________________________________ ⚠️ Important Notes for CompTIA A+ Exam • Switches are layer 2 devices that forward frames based on MAC addresses. • Use straight-through cables for computer-to-switch connections. • Proper subnet configuration ensures devices can communicate on the same LAN. • Check link lights to confirm physical connectivity before troubleshooting further. ________________________________________ #CompTIAaPlus #NetworkSwitch #LANConnectivity #EthernetSetup #ITNetworking
