QNAP QSW-M7308R-4X 12-Port 100GbE and 25GbE L3 Lite Managed Switch

Build a Compact 100GbE Backbone for Demanding Workloads The QNAP QSW-M7308R-4X combines four 100GbE QSFP28 ports and eight 25GbE SFP28 ports in a half-width rackmount chassis. It gives high-speed storage, servers and media workflows a focused aggregation point with 1200Gbps switching capacity. QSS Pro adds L3 Lite management, including static routing and DHCP server functions, while MC-LAG provides an option for a correctly designed redundant switch pair. Choose the required media and firmware as part of the full network design.

Plan the endpoint adapters, storage performance and network layout together: a published switching-capacity figure is not a guarantee of every application's transfer rate. Use the Media and Breakout Layout That Fit The SFP28 interfaces support qualified 25GbE, 10GbE and 1GbE media. Supported 100GbE QSFP28 ports can use QSFP28-to-four-SFP28 breakout DAC or AOC cables, with up to sixteen 25GbE breakout sub-ports across those four ports. Breakout operation divides the selected port into its supported lanes; it does not add sixteen independent 100GbE connections. Match Exact Compatible Connections QNAP lists compatible connection accessories including CAB-DAC15M-Q28, CAB-DAC15M-Q28B4, CAB-DAC15M-SFP28 and TRX-25GSFP28-SR. Choose the cable or transceiver for the switch port and the exact peer adapter or switch, including speed and distance. These accessories are separate from the switch package. The additional Gigabit RJ45 management port and RJ45 console port are for administration, not copper 10GbE data uplinks. Manage Segments with QSS Pro L3 Lite Use supported static routes, IPv4/IPv6 interfaces and DHCP server functions alongside VLANs and access controls. Units supplied with the earlier QSS software can be updated to QSS Pro according to QNAP's supported upgrade path. Confirm and configure the required software functions before deploying the switch into a live network. Design Redundancy with a Compatible Switch Pair MC-LAG and LACP provide different building blocks for a network with redundant paths. MC-LAG requires a compatible switch pair, correctly configured links and a suitable endpoint design. A single switch or a second cable alone does not remove every point of failure; test the intended recovery behaviour before production use. Plan for RDMA and Media Traffic Current QNAP software offers PFC, ECN and QoS for supported lossless-Ethernet designs, while PTP and multicast controls support appropriate AV-over-IP deployments. Use firmware that supports the selected functions and configure compatible endpoints throughout the fabric. The hardware alone does not establish a correctly tuned RDMA or time-synchronised network. Fit High-Speed Switching into Less Rack Width The metal half-width chassis uses active cooling and an internal 100–240V AC supply. Standard mounting hardware is included. QNAP also lists the optional SP-EAR-QSW2FOR1-01 kit for an appropriate side-by-side mounting arrangement; select it only when that installation requires it. Summary The QSW-M7308R-4X suits a planned 100GbE and 25GbE network that needs compact mounting and QSS Pro L3 Lite control. Its uplink, breakout and redundancy options are useful when the exact media, software and peer systems are matched to the deployment. Frequently Asked Questions How Many Data Connections Are Available?ExpandCollapse The switch has four 100GbE QSFP28 ports and eight 25GbE SFP28 ports. The separate Gigabit management connection and RJ45 console are administration interfaces, not additional high-speed data ports. Can a 100GbE Port Connect to Four 25GbE Devices?ExpandCollapse Yes, with a supported QSFP28-to-four-SFP28 breakout DAC or AOC cable and the required port configuration. QNAP supports breakout on the four QSFP28 ports, giving up to sixteen 25GbE breakout sub-ports across them. Does It Provide L3 Lite Management?ExpandCollapse Yes, through supported QSS Pro software. It includes static routing, IPv4/IPv6 interfaces and DHCP server functions. Older QSS installations should follow QNAP's supported update path before these features are used. Does MC-LAG Require a Second Switch?ExpandCollapse MC-LAG is a multi-chassis design, so it needs a correctly configured compatible switch pair and supported endpoint connections. The second switch and network cabling are separate purchases. Are Optical Modules and Network Cables Included?ExpandCollapse The standard package contains the switch, power cord, rackmount kit, foot pads, screws and installation guide. Select supported optics, DACs, AOCs or fibre cables separately for the exact ports and link distances. What Warranty and Mounting Format Does It Have?ExpandCollapse It is a half-width rackmount switch with a 2-year warranty. Standard mounting hardware is included. A specialised side-by-side installation may use the separately selected compatible QNAP mounting kit. Read more
