Introduction
This manual provides detailed instructions for the setup, operation, maintenance, and troubleshooting of the Arista DCS-7280SE-72 Ethernet Switch. The 7280SE‑72 is a high-performance switch designed for data center and enterprise networks, delivering two 100GbE uplinks through the use of Arista MXP interfaces and embedded optics. Each MXP port enables twelve 10GbE, three 40GbE, or one 100GbE for a wide choice of cost‑effective connections.
Setup and Installation
1. Unboxing
Carefully remove the switch and all accessories from the packaging. Verify that all components are present, including the switch unit, power cords, and any included documentation or accessories. The product may include a DVD with additional resources.
2. Physical Installation
The Arista DCS-7280SE-72 is designed for rack mounting. Securely install the switch in a standard 19-inch equipment rack using appropriate mounting hardware. Ensure adequate airflow around the unit for proper cooling. Connect the power cords to the power supply units at the rear of the switch and then to a grounded AC power source.
3. Initial Configuration
For initial configuration, connect a console cable from your management workstation to the console port on the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control. Power on the switch and follow the on-screen prompts to set up basic network parameters such as IP address, subnet mask, and default gateway.

Operation
1. Powering On
Once connected to power, the switch will automatically begin its boot sequence. Observe the system status LEDs on the front panel to confirm successful power-on and system initialization.
2. LED Indicators
The front panel features various LED indicators for system status, port activity, and power. Refer to the detailed LED status guide in the official Arista documentation for specific meanings of each indicator, which are crucial for quick diagnostics.
3. Port Connectivity
Connect network devices to the SFP ports using appropriate transceivers and fiber optic cables. For 100GbE uplinks, use compatible MXP interfaces and cables. Ensure proper cable seating and observe port LEDs for link status and activity.
4. Software Interface
The Arista DCS-7280SE-72 operates on Arista EOS (Extensible Operating System). Access the command-line interface (CLI) via console, SSH, or Telnet for advanced configuration, monitoring, and management tasks. Refer to the Arista EOS documentation for comprehensive command references and configuration examples.
Maintenance
1. Cleaning
Regularly inspect the switch for dust accumulation, especially around ventilation openings and fan inlets/outlets. Use a soft, dry cloth or compressed air to gently clean the exterior. Do not use liquid cleaners directly on the device.
2. Firmware Updates
Periodically check the Arista support website for the latest EOS firmware updates. Applying updates can provide new features, performance enhancements, and critical security patches. Always follow the recommended update procedures provided by Arista to avoid service interruptions.
3. Component Replacement
The Arista DCS-7280SE-72 features hot-swappable power supply units and fan modules, allowing for replacement without powering down the entire switch. When replacing a component, ensure the replacement part is compatible and follow the specific removal and installation instructions provided in the official Arista hardware guide.

Troubleshooting
1. Common Issues
- No Power: Verify power cord connections, check power outlets, and ensure power supply units are properly seated.
- No Link on Port: Check cable integrity, ensure correct transceiver type, verify connected device is powered on and configured correctly.
- Network Connectivity Problems: Confirm IP address configuration, check routing tables, and verify VLAN assignments.
2. Diagnostic LEDs
Utilize the front panel LEDs (Status, Link/Activity) to quickly diagnose issues. A solid green link LED indicates a successful connection, while a blinking LED indicates data activity. Refer to the official Arista documentation for a complete guide to LED status codes.
3. Reset Procedures
In cases of system unresponsiveness, a soft reboot can be initiated via the CLI. For more severe issues, a hard power cycle may be necessary by disconnecting and reconnecting power. Exercise caution with factory reset procedures, as they will erase all configurations.
