4.2 Use a network diagram provided by an engineer to attach the appropriate cables.
Network diagram shows the layout of the network with designated cables. Connectors, layout, and the end points. Different terms used in interpretation of network diagram are given below:
1. Patch Cables: Patch cables are used to connect devices within a local area network. They are typically short Ethernet cables with RJ-45 connectors at both ends. To connect devices like computers, servers, switches, and routers, use patch cables to connect the Ethernet ports on these devices.
2. Switches and Routers: Switches are used to create local networks by connecting multiple devices together. Routers, on the other hand, connect different networks together. Connect devices to switches and routers using patch cables. Ensure that the cables are properly inserted into the appropriate Ethernet ports on the devices.
3. Small Topologies: In small network topologies, devices are typically connected in a star or tree-like configuration. Each device connects directly to a central switch or router. Use patch cables to connect the devices to the switch or router, ensuring each device is connected to the appropriate port.
4. Power: Network devices like switches and routers often require power to operate. Ensure that power cables are properly connected to the power outlets and the respective devices. Follow the manufacturer's instructions for proper power connections.
5. Rack Layout: In larger network setups, devices may be organized in server racks or cabinets. Pay attention to the rack layout and cable management to maintain an organized and tidy environment. Use cable management solutions, such as cable ties or cable management panels, to keep cables organized and prevent tangling.
4.3 Identify the various ports on network devices. Console port, serial port, fiber port, Ethernet ports, SFPs, USB port, PoE
Network devices, such as switches, routers, and firewalls, often have various ports that serve different purposes. Here are some commonly found ports on network devices:
1. Console Port: The console port is used for local management and configuration of network devices. It typically uses an RS-232 serial connection and requires a console cable to connect to a computer or terminal for accessing the device's command-line interface (CLI).
2. Serial Port: Some network devices may have serial ports, which are used for serial communication. Serial ports can be used for various purposes, such as connecting to external modems or console servers.
3. Fiber Port: Fiber ports, also known as fiber optic ports, are used for connecting fiber optic cables. These ports are designed to transmit and receive data using light signals. They are commonly used for high-speed and long-distance network connections.
4. Ethernet Ports: Ethernet ports are the most common ports found on network devices. They are used for connecting devices using Ethernet cables, which typically have RJ-45 connectors. Ethernet ports support different speeds, such as 10/100/1000 Mbps (Fast Ethernet/Gigabit Ethernet), and may have indicators to display link and activity status.
5. SFP (Small Form-factor Pluggable) Ports: SFP ports are modular ports found on some network devices, such as switches. They can accept SFP transceivers, which are hot-swappable modules that allow for flexible connectivity options. SFP ports support various types of optical or copper interfaces, including different types of fiber connections, Ethernet, or other protocols.
6. USB Port: USB (Universal Serial Bus) ports are sometimes present on network devices. They can be used for various purposes, such as connecting external storage devices, USB modems, or for firmware upgrades.
7. PoE (Power over Ethernet): PoE ports allow for both data and power transmission over a single Ethernet cable. These ports are used to connect PoE-enabled devices, such as IP phones, wireless access points, or IP cameras, eliminating the need for a separate power source.
It's important to note that the availability and specific types of ports on network devices can vary depending on the device's model, purpose, and capabilities. Therefore, it's always recommended to refer to the device's documentation or specifications for accurate information on the ports it supports.
