8-Port 10GbE Layer 2 Web Managed Switch

QNAP QSW-M804-4C

The QSW-M804-4C combines four dedicated 10GbE SFP+ ports with four 10GbE SFP+/RJ45 combo ports, providing flexible fibre and copper connectivity for businesses and organisations upgrading to a managed 10GbE network.

What is the QNAP QSW-M804-4C?

The QSW-M804-4C is an eight-port Layer 2 Web Managed Switch designed for high-speed file transfers, simultaneous access to large files, video and multimedia workflows, and bandwidth-demanding virtualisation tasks. Its QNAP Switch System web interface provides entry-level network management through an overview dashboard, port controls and guided settings.

8 Ports Four 10GbE SFP+ ports and four SFP+/RJ45 combo ports

10GbE High-speed fibre and copper network connectivity

5 Speeds RJ45 combo ports support 10G, 5G, 2.5G, 1G and 100M

Layer 2 LACP, VLAN, QoS, ACL, LLDP, RSTP and IGMP Snooping

Flexible 10GbE Fibre and Copper Deployment

Connect servers, storage and other network devices through SFP+ or multi-speed RJ45 interfaces.

The QSW-M804-4C includes four dedicated SFP+ fibre ports and four SFP+/RJ45 copper combo ports. Direct Attach Copper cables can be used with the SFP+ interfaces when connecting servers inside a rack, while the RJ45 interfaces support 10GbE through Cat 6a or higher-category cabling.

The RJ45 combo interfaces are compatible with 10GbE and NBASE-T technologies and support five network speeds: 10G, 5G, 2.5G, 1G and 100M. The achievable connection speed depends on the cable type and cable length.

Cabling note: When the distance between the switch and connected device is less than 45 metres (148 feet), Cat 6 cable can be used to achieve 10Gb/s speeds.

QSS: Intuitive Network Management

The QNAP Switch System provides a visual, web-based interface for configuring and monitoring the switch.

Overview Dashboard

View real-time system information, port connection status and port traffic from a central dashboard.

Visual Port Management

The graphical interface reflects the switch’s physical ports to make configuration and monitoring easier.

Guided Configuration

Settings guidance, status charts and flat control layers help simplify network setup and ongoing management.

One-Click Updates

QSS supports one-click online firmware updates to help IT administrators keep the switch software current.

Bandwidth and Packet Management

Layer 2 controls help administrators manage traffic, organise connected devices and allocate network resources.

Link Aggregation

LACP combines multiple network connections to increase throughput and provide protection against a connection failure.

VLAN

Virtual LAN functionality allows selected devices from different physical network segments to be organised into a logical network.

Quality of Service

QoS helps prioritise bandwidth usage and optimise the allocation of available network resources.

IGMP Snooping

IGMP Snooping assists in reducing unnecessary multicast traffic, minimising bandwidth loss and limiting network information leakage.

Network Reliability and Security Functions

Access controls, device discovery and loop-prevention features help administrators maintain a stable Layer 2 network.

Access Control Lists

ACL functionality provides access controls that can help administrators strengthen network security.

LLDP

Link Layer Discovery Protocol supports device discovery and assists with network troubleshooting.

Rapid Spanning Tree Protocol

RSTP supports loop prevention, redundant network paths and expandable small-to-medium network deployments.

IEEE 802.3x Flow Control

Full-duplex flow control helps balance data transmission and avoid packet loss during periods of unequal bandwidth.

High-Speed Network Applications

Flexible 10GbE connectivity supports storage, multimedia and other bandwidth-demanding environments.

The QSW-M804-4C can be used with NAS devices featuring built-in 10GbE SFP+ or 10GBASE-T ports, as well as NAS models equipped with compatible 10GbE network adapters. The supplied product information also identifies QNAP Thunderbolt 3 to 10GbE and USB 3.2 Gen 1 to 5GbE network adapters as parts of QNAP’s wider high-speed networking range.

These connection options can support photo and video editing, virtualisation, large-file transfers and simultaneous multi-workstation access to shared files.

Rackmount or Desktop Installation

A modern enclosure and included rackmount kit provide flexible placement options.

The QSW-M804-4C features a compact rackmount design suitable for business networks, server rooms and modern office environments. A rackmount kit is included to provide additional installation flexibility.

The QSW-M804-4C is made in Taiwan and is presented as a reliable managed networking solution for organisations adopting 10GbE connectivity.
