#Networking Devices

🟢 This image explains the main components of a network rack and how data and power flow inside a structured network. It shows a complete rack setup with labeled devices arranged vertically for efficient operation and management. At the top, the Router connects the internal network to the Internet ( WAN ). Below it, the Firewall provides security by filtering and protecting network traffic. The Network Switch manages LAN traffic and distributes connections to multiple devices. The Patch Panel is used for cable termination and organization, ensuring clean and structured cabling. Servers provide network services such as applications, file storage, and databases. For power management, the rack includes a UPS ( Uninterruptible Power Supply ) that provides backup power during outages, and a PDU ( Power Distribution Unit ) that distributes electricity to all devices. At the bottom, cooling and cable management systems maintain proper airflow and reduce heat. The diagram also illustrates the complete network flow : #Internet → #Router → #Firewall → #Switch → #Patch_Panel → End Devices ( PCs, printers, access points ). Overall, the image presents a clear and professional overview of how a network rack is organized and how data and power move through the system.

Major Homelab Upgrade to 100Gbps The backbone of my homelab is now running at 100 Gbps over QSFP28. The Mikrotik router, two D-Link datacenter switches, and my main server are all upgraded to full 100 Gb connectivity. Alongside the core network, I also deployed a second 20 Gb network using Zyxel hardware for isolated traffic. Core design highlights: • 100Gb QSFP28 backbone • VLAN segmentation for Lab / Storage / Management • Independent 20Gb network for security and routing scenarios Hardware Used • Mikrotik ROSE Data Server (RDS) – main router/firewall handling routing, BGP, and L3 • Zyxel USG 700H – security gateway for the secondary network, VPN & UTM • D-Link DXS-3610-54S/SI/E – 10/25/100Gb L3 switch for Core/Distribution • HPE ProLiant ML350 Gen11 with 4× NVIDIA SFP28 – server with four 25 Gb links (LAG/LACP for 100 Gb aggregates) #homelab #networking #100GbE #QSFP28 #server

Networking Devices — The Building Blocks of Every Network Ever wondered how data travels smoothly from your laptop to the cloud? That’s the magic of Networking Devices — the real heroes behind every connection. 💡 Top Networking Devices You Must Know: 🔹 Hub: Basic device that sends data to all connected systems. 🔹 Switch: Smarter device that connects multiple devices in a LAN and forwards data only where it’s needed. 🔹 Router: Connects different networks and directs traffic intelligently. 🔹 Firewall: Protects your network from cyber threats and intrusions. 🔹 Access Point: Enables wireless connectivity for devices. 🔹 Modem: Connects your home or office network to the Internet. 👉 Follow @guinettechnologies for daily insights on Networking | SD-WAN | Cybersecurity | Cloud | Automation ◆ WhatsApp/Call for Enquires → https://wa.me/919289682701 #cybersecurity #ethicalhacking #networksecurity #ccna #ccnp #networkengineer #infosec #itsecurity #guinettechnologies #cisconetworking #techreels #devops #sdwan #cisco #itsecurity #firewall #fyp #instaviews

Passando pelo stand da @arsitecbrasil na abrint 2024 pude ver esse lindo rack montado pelo @rachidferreirarafael .

I’ve deployed an Ookla Speedtest server named ATEFI.CH on my home network: Capacity: up to 50 Gbps, Dual-stack: IPv4/IPv6 with TLS Try it: open the Speedtest app and search “ATEFI.CH” Visibility: Netdata + ntopng for real-time system health, traffic analytics, and connected devices Core Speedtest service remains unchanged; added secure monitoring and access controls. @speedtestdotnet @init7_net @ooklaconnectivity #speedtest #ookla #homelab #networking #netops #selfhosted #server #linux #ubuntu #ipv6 #ipv4 #fiber #gigabit #sysadmin #devops #monitoring #observability #netdata #ntopng #grafana #nginx #telecom #isp #internet #cloud

Maybe this is why everyone blames the network! #networking #datacenter

I’m on a mission to make network engineering cool. We have a big problem online today, and few people recognize it. Every time I open my feed, I see: - AI - cloud - cybersecurity - data engineering - software developers but VERY few network engineers. The next generation is making career decisions based on what they see on the internet. Everything is built on the network. How will they know how cool it is if we don’t tell them? It’s more important than ever to make sure networking has representation to younger students choosing a career field. It’s up to us to carry the torch to the next generation!! P.S. comment WOOOO for network engineering #informationtechnology #networkengineer #ccna #ccnp #workingintech
