11-Port Unmanaged Desktop Switch
QNAP QSW-308-1C
A cost-effective entry-level switch with three 10GbE SFP+ connections, including one SFP+/RJ45 combo port, plus eight Gigabit Ethernet ports. Its compact fanless design supports quiet, high-speed networking in homes and offices.
What is the QNAP QSW-308-1C?
The QSW-308-1C is an unmanaged desktop switch designed for building a hybrid 10GbE and Gigabit Ethernet network. It provides two dedicated 10GbE SFP+ ports, one 10GbE SFP+/RJ45 combo port and eight 1GbE RJ45 ports, with a total switching capacity of 76Gbps.
3 × 10GbE
Two dedicated SFP+ ports and one SFP+/RJ45 combo port
8 × 1GbE
Gigabit RJ45 ports for connecting network devices
76Gbps
Total switching capacity with 38Gbps non-blocking throughput
Fanless
Ventilated desktop design for silent operation
Flexible 10GbE and Gigabit Connectivity
Connect devices with different interfaces and bandwidth requirements.
2 × 10GbE SFP+
Dedicated 10G-only SFP+ ports for direct SFP+ connections.
1 × Combo Port
Use either the 10GbE SFP+ interface or the multi-speed RJ45 interface.
8 × Gigabit RJ45
Connect computers, NAS devices and other Gigabit Ethernet equipment.
Port limitation: The 10GbE SFP+ ports are not backward compatible with 1GbE SFP modules. The RJ45 side of the combo port supports 10G, 5G, 2.5G, 1G and 100M speeds.
Five-Speed 10GBASE-T and NBASE-T Connectivity
Use the copper combo port with a range of Ethernet connection speeds.
The RJ45 interface in the SFP+/RJ45 combo port supports five network speeds: 10G, 5G, 2.5G, 1G and 100M. Auto-negotiation selects the optimal supported speed and duplex mode when different devices are connected.
Depending on the cable type and cable length, the copper interface can provide higher transmission speeds while allowing existing network cabling to be reused.
To achieve a 10Gb/s connection over a distance of less than 45 metres, the supplied product information states that a Category 6 cable can be used.
Plug-and-Play Unmanaged Operation
No switch configuration is required for normal operation.
Silent Fanless Design
A fanless, ventilated enclosure supports silent operation while maintaining network performance.
Compact Desktop Format
The compact desktop enclosure is designed to blend into home and office network environments.
Build a Hybrid High-Speed Network
Combine fibre, direct-attach copper and RJ45 connections.
Direct attach copper cables can be used to connect the SFP+ ports directly to compatible SFP+ devices. A 10G-SFP-T copper transceiver module can also be used to connect 10GBASE-T or NBASE-T devices through Category 6, Category 5 or Category 5e cabling.
The QSW-308-1C can be combined with supported QNAP 10GbE network expansion cards, Thunderbolt 3-to-10GbE network adapters and USB 3.2 Gen 1-to-5GbE network adapters to create a high-speed network for large-file transfers, photo and video editing, virtualization and other bandwidth-demanding tasks.
10GbE-Enabled QNAP NAS Connectivity
Connect compatible QNAP NAS systems to a higher-speed network.
QNAP NAS models with built-in 10GbE interfaces, or compatible NAS systems upgraded with a 10GbE network adapter, can be connected to the QSW-308-1C. The higher-bandwidth network can support demanding workflows such as virtualization, databases, high-resolution video editing and file sharing.
Frequently Asked Questions
Common questions about the QNAP QSW-308-1C.
Is the QSW-308-1C a managed switch?
No. It is an unmanaged plug-and-play switch that does not require configuration for normal operation.
How many ports does the QSW-308-1C provide?
It has 11 ports in total: two dedicated 10GbE SFP+ ports, one 10GbE SFP+/RJ45 combo port and eight 1GbE RJ45 ports.
Which speeds are supported by the RJ45 combo port?
The RJ45 side of the combo port supports 10G, 5G, 2.5G, 1G and 100M connection speeds.
Can the SFP+ ports use 1GbE SFP modules?
No. The supplied product information states that the 10GbE SFP+ ports are not backward compatible with 1GbE SFP modules.
Can the SFP+ and RJ45 sides of the combo port be used at the same time?
The product provides one combo port, meaning it is represented by a shared SFP+/RJ45 connection rather than two additional independent ports.
Does the QSW-308-1C contain a cooling fan?
No. It uses a fanless, ventilated design for silent operation.
What is the switching capacity?
The QSW-308-1C has a switching capacity of 76Gbps and total non-blocking throughput of 38Gbps.
Are there any listed network-adapter compatibility limitations?
Yes. The supplied datasheet warns that compatibility issues with the Intel X520 Ethernet network adapter may cause the 10GbE ports to switch randomly between port-up and port-down states.
What warranty is listed for the QSW-308-1C?
The supplied datasheet lists a two-year warranty.
Compatibility notice: Compatibility issues with the Intel X520 Ethernet network adapter may cause the 10GbE ports to switch randomly between port-up and port-down states.
