QNAP QSW-M408-4C NBASE-T Combo Managed Network Switch

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device across different regions.

A list of the cable categories or standards that a product can use, such as Cat5e, Cat6, Cat6a, Cat7, Fiber, HDMI, USB, etc. The values are separated by commas and represent the types of cables compatible with the device.

A list of the cable types that are supplied with the product, such as USB, HDMI, VGA, DisplayPort, LAN (RJ‑45), SATA, audio or other relevant connectors.

A list of official certifications or compliance marks that the product has received from regulatory bodies, safety organizations, or industry standards groups. Each entry represents a distinct certification such as CE, FCC, RoHS, UL, or WEEE, and may include additional details like version numbers or specific test reports.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

Represents how many console ports are physically present on the product. The value is a simple integer indicating the total count of console connectors, regardless of type or version.

A comma‑separated list of the copper Ethernet standards supported by a device, such as 10BASE‑T, 100BASE‑TX, or 1000BASE‑T. Each entry indicates a specific speed and physical specification that the product can transmit over its RJ‑45 ports.

A comma‑separated list of the DHCP roles and options that a device can provide or use, such as server, client, relay, snooping, option 82 support, and IPv6 variants. The value may contain multiple items for a single product.

Represents the count of physical Gigabit Ethernet (10/100/1000 Mbps) copper interfaces available on a device. The value is an integer indicating how many separate RJ‑45 connectors support Gigabit speeds, regardless of other port types or generations.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

The total count of SFP+ (Small Form-factor Pluggable) transceiver modules physically installed in a networking device, such as switches or routers. This value indicates how many separate SFP+ slots are populated and can be used for high‑speed fiber or copper connections.

The largest Ethernet frame size in bytes that the device can transmit or receive without fragmentation. This value determines the maximum payload that can be sent in a single network packet, which can improve throughput for high‑bandwidth applications.

The highest electrical power that a device can draw or consume during operation, expressed in watts (W). It represents the peak energy usage of the product and is useful for estimating maximum power requirements, comparing efficiency across similar devices, and ensuring compatibility with power supplies.

The total count of individual cooling fans that are part of the product or its components. This value indicates how many separate fan units are installed, such as in a graphics card, CPU cooler, case, or other hardware assemblies.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

Indica los estándares o velocidades que soportan los puertos RJ‑45 presentes en el producto, como Fast Ethernet (10/100 Mbps), Gigabit Ethernet (1 Gbps) o 10 Gigabit Ethernet. Cada valor describe una capacidad específica del conector y permite comparar la compatibilidad de red entre dispositivos.

The network layer(s) that a device can operate at, expressed as a string such as "L2", "L3" or combinations like "L2/L3". This attribute indicates the protocol stack level supported by the hardware or firmware.

The classification of a network switch based on its management capabilities, such as Managed or Unmanaged. This attribute indicates whether the device can be configured and monitored remotely (Managed) or operates with fixed settings without remote configuration (Unmanaged). It helps users choose a switch that matches their networking expertise and control requirements.
