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.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

Maximum theoretical speed at which a device can send or receive data over its Ethernet LAN interface, expressed in megabits per second (Mbps) or gigabits per second (Gbps). It represents the upper bound of throughput under optimal conditions and is useful for comparing network performance between devices with wired connectivity.

Indicates whether the device can receive firmware updates, allowing improvements in functionality and security fixes through downloads from the manufacturer.

The total amount of internal flash memory available in a device, expressed as a data size (e.g., megabytes or gigabytes). This attribute indicates how much data can be stored on the device’s built‑in flash storage.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

Indicates whether the product is designed to be installed inside a computer system or other device, such as an internal hard drive, SSD, network card, or component. A value of "Yes" means it can be mounted within the chassis; a value of "No" indicates it is intended for external use.

The total amount of internal memory available in a device, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold for active processes and affects multitasking performance.

List of Linux operating systems that the product can run or support, including specific versions and architectures when relevant. Each value represents a distinct Linux distribution or kernel version supported by the hardware or software.
