Includes four 10Gb E SFP+/ RJ45 combo ports. Compatible with 10Gb E and NBASE-T technologies to support five speeds (10G / 5G / 2. 5G / 1G / 100M) using existing cables. The QNAP Switch System (QSS) is easy to use and provides an overview dashboard, port management and setting guide, making central network management intuitive. Provides Layer 2 management features (such as LACP, VLAN, ACL and LLDP) for IT staff to efficiently control network bandwidth and enhance security. One of the few web-managed switches that supports Rapid Spanning Tree Protocol (RSTP). Easily and efficiently deploy small/medium-scale networks that support expansion, redundancy, and loop prevention. Compliant with IEEE 802. 3az Energy Efficient Ethernet and IEEE802. 3x Flow Control in full-duplex mode, the QSW-M804-4C avoids packet loss from unparalleled bandwidth and reduces power consumption for low-speed and inactive connections. QSS can be updated with just one click, helping IT staff ensure their network security. The QSW-M804-4C is a Layer 2 Web Managed Switch with four 10Gb E SFP+ ports and four 10Gb E SFP+/RJ45 combo ports that enables blazing-fast transfer speeds, simultaneous multi-workstation access to large files (ideal for video editing and multimedia), and empowers bandwidth-demanding tasks like virtualization. Supporting Layer 2 switching and providing a user-friendly entry-level network management solution, the QSW-M804-4C is an affordable way for businesses and organizations to fully embrace 10Gb E connectivity.
