how to install Extreme Networks 8520-48Y Ethernet Switch

• Unpack the switch and verify all components against the packing list. Inspect connectors and the chassis for any transit damage before installation.
• Mount the switch in a standard 19-inch rack using the included rails and screws. Ensure adequate airflow around the chassis and keep intake vents unobstructed.
• Install any required modular components or uplink expansion modules according to your network design. Power down the switch and follow the hot-swap procedure if you’re upgrading modules in-place.
• Connect power cords and verify power readiness. Use an Uninterruptible Power Supply (UPS) to protect against outages and ensure stable operation during maintenance windows.
• Attach cabling for 25GBASE-T ports and 100GBASE-X uplinks. Label cables for clarity and route them to prevent strain, interference, or accidental disconnections.
• Power on the device and access the management interface (CLI or GUI) to perform initial configuration. Set VLANs, QoS policies, link aggregation, and security features according to your network design.
• Validate connectivity with representative workloads. Run diagnostics, verify latency and throughput, and ensure all uplinks reach the core or aggregation layer without packet loss.
