Ubiquiti USW-Flex-2.5G-8-PoE UniFi Switch Flex 2.5G PoE User Manual

Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of the Ubiquiti USW-Flex-2.5G-8-PoE UniFi Switch Flex 2.5G PoE. This device is a flexible, 8-port 2.5 GbE PoE++ switch with a 10 GbE RJ45/SFP+ combination uplink port. It can be powered with PoE+++ or an AC power adapter (sold separately).

Key features include:

• (8) 2.5 GbE PoE++ output ports
• (1) 10 GbE PoE+++ input port for power / SFP+ port combo
• 196W PoE availability with optional AC power adapter

Package Contents

Verify that your package contains the following items:

• Ubiquiti USW-Flex-2.5G-8-PoE Switch
• Mounting accessories

Note: An AC power adapter is sold separately and is required for certain power configurations, especially for full PoE++ availability.

Setup

Powering the Device

The USW-Flex-2.5G-8-PoE can be powered in two ways:

1. PoE+++ Input: Connect a PoE+++ (802.3bt) compliant power source to the 10 GbE RJ45/SFP+ combination uplink port (Port 9). This method provides power to the switch and allows for data uplink.
2. AC Power Adapter: Connect an optional 54V DC AC power adapter (sold separately) to the DC input port. This method is necessary to achieve the full 196W PoE availability for connected devices.

Important: Ensure the power source meets the device's requirements to prevent damage.

Connecting Network Devices

Once powered, connect your network devices (e.g., computers, access points, cameras) to the 2.5 GbE PoE++ output ports (Ports 1-8) using standard Ethernet cables. These ports provide both data connectivity and Power over Ethernet (PoE) to compatible devices.

Use the 10 GbE RJ45/SFP+ combination uplink port (Port 9) to connect the switch to your main network infrastructure (e.g., router, core switch) for high-speed data transfer.

Operating Instructions

LED Indicators

The switch features LED indicators to provide status information:

• System LED: Indicates device status (e.g., booting, ready, error). Refer to the Ubiquiti UniFi documentation for specific LED patterns.
• Port LEDs: Each 2.5 GbE port has LEDs indicating link/activity and PoE status.
  • Link/Activity: Solid green for active link, blinking for activity.
  • PoE Status: Indicates if PoE is being supplied to the connected device.

Network Management

The USW-Flex-2.5G-8-PoE is part of the Ubiquiti UniFi ecosystem. It is managed through the UniFi Network Application, which can be run on a UniFi Cloud Key, UniFi Dream Machine, or a self-hosted server. For initial setup and advanced configuration, refer to the UniFi Network Application documentation available on the Ubiquiti support website.

Through the UniFi Network Application, you can:

• Monitor port status and traffic.
• Configure PoE settings for individual ports.
• Update firmware.
• View network topology.
• Manage VLANs and other network settings.

Maintenance

To ensure optimal performance and longevity of your USW-Flex-2.5G-8-PoE switch, follow these maintenance guidelines:

• Cleaning: Periodically clean the exterior of the device with a soft, dry cloth. Do not use liquid cleaners or aerosols. Ensure ventilation openings are free from dust and debris.
• Firmware Updates: Regularly check for and apply firmware updates through the UniFi Network Application. Firmware updates often include performance improvements, bug fixes, and security enhancements.
• Environmental Conditions: Operate the device within its specified environmental ranges (temperature, humidity) to prevent overheating or damage.
• Cable Management: Ensure all connected cables are properly routed and secured to prevent accidental disconnections or damage.

Troubleshooting

If you encounter issues with your USW-Flex-2.5G-8-PoE switch, consider the following troubleshooting steps:

• No Power:
  • Verify that the PoE+++ input or the optional AC power adapter is securely connected and providing power.
  • Check the power source (e.g., PoE injector, PoE switch, wall outlet) for functionality.
• No Link/Connectivity:
  • Ensure Ethernet cables are properly seated in both the switch port and the connected device.
  • Test with a different Ethernet cable.
  • Verify that the connected device is powered on and functioning correctly.
  • Check the UniFi Network Application for port status and error messages.
• PoE Not Working:
  • Confirm that the connected device is PoE compatible and within the power budget of the switch.
  • If using PoE+++ input, ensure the power source provides sufficient power for all connected PoE devices. Consider using the optional AC power adapter for maximum PoE availability.
  • Check PoE settings for the specific port in the UniFi Network Application.
• Device Unresponsive:
  • Perform a power cycle by disconnecting and reconnecting the power source.
  • If the issue persists, consider performing a factory reset (refer to Ubiquiti documentation for the reset procedure).
