When installing a Local Area Network (LAN), various tests are performed to ensure that the network operates correctly and meets performance requirements. Here are some common types of LAN installation tests:
-
Cable Testing:
- Continuity Testing: Ensures that the wiring within the cables is intact and that there are no breaks in the wires.
- Wiremap Testing: Checks that the pins on either end of a cable are connected in the correct configuration (T568A or T568B).
- Length Testing: Verifies that the cable length is within the acceptable limits (typically 100 meters for Ethernet).
- Attenuation Testing: Measures the signal loss over the distance of the cable to ensure it is within specified limits.
- Cross-talk Testing: Identifies interference between wires within the same cable or between adjacent cables.
-
Network Device Configuration Testing:
- Switch Configuration: Verifies that switches are properly configured for VLANs, trunking, and other settings.
- Router Configuration: Ensures routers are set up correctly, including routing protocols and access control lists (ACLs).
- Firewall Testing: Checks that firewall rules and policies are implemented and functioning as intended.
-
Network Performance Testing:
- Throughput Testing: Measures the data transfer rate across the network and compares it against expectations.
- Latency Testing: Assesses the time it takes for data to travel from one device to another, indicating potential delays in the network.
- Packet Loss Testing: Measures the percentage of packets that are lost during transmission, indicating potential network issues.
-
Wireless Network Testing (if applicable):
- Coverage Testing: Evaluates the range and signal strength of the wireless network to ensure full coverage.
- Interference Testing: Identifies any sources of interference (like other wireless devices) that may impact performance.
- Security Testing: Verifies that the wireless network is secured, including testing encryption and access controls.
-
Load Testing:
- Simulates multiple users or devices to ensure that the network can handle expected loads without degradation in performance.
-
End-to-End Testing:
- Tests the complete network path from one endpoint to another to verify that all components work together seamlessly.
-
Functionality Testing:
- Confirms that all network services (e.g., DHCP, DNS, file sharing) are functioning correctly.
-
Documentation and Compliance Testing:
- Ensures that the network installation adheres to design specifications and industry standards, including documentation of configurations and network maps.
Performing these tests after installation helps identify any issues or bottlenecks within the LAN, allowing for necessary adjustments before the network goes live for end users.
