Zyxel USG Flex 500 Device Only Firewall

Indicates whether the product includes a built‑in fan that can be used for cooling or ventilation without requiring an external unit. A value of "Yes" means the device has such a fan; "No" means it does not.

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.

Represents the total count of Ethernet LAN (RJ‑45) interfaces available on a product. The value is an integer indicating how many physical Ethernet ports are present, regardless of speed or generation.

The maximum rate at which a firewall can process or transmit network traffic, expressed in megabits per second (Mbits/s). It indicates the capacity of the device to handle data flow without bottlenecks.

Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.

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 amount of thermal energy a product can dissipate, expressed in a standard unit such as BTU per hour or watts. It indicates the cooling requirement and helps compare how much heat the device generates during operation.

The electrical current drawn by a device when powered, expressed in amperes (A). It indicates how much current the product consumes from its power source during normal operation and can be used to assess compatibility with power supplies or USB ports.

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 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.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A list of cryptographic and authentication methods that a device can use for secure communication or data protection. Each entry represents a distinct algorithm or protocol, such as encryption ciphers (e.g., AES, WEP), authentication mechanisms (e.g., RADIUS, WPA‑PSK), or network security protocols (e.g., HTTPS, SSL/TLS). The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The total count of USB 3.2 Gen 1 (also known as USB 3.1 Gen 1 or SuperSpeed) ports available on the device, indicating how many peripherals can be connected simultaneously via this interface.

A list of the VPN protocols that a device can establish, such as PPTP, L2TP, IPSec, OpenVPN, and related pass‑through or server modes. The values are typically separated by commas and may include variations like "IPSec Pass‑Through" or "OpenVPN Server" to indicate specific capabilities.

The maximum rate at which a VPN device can process or transmit encrypted network traffic, expressed in megabits per second (Mbits/s). It indicates the capacity of the VPN appliance to handle secure data flow without bottlenecks.

Represents the count of virtual private network (VPN) tunnels that a device or service can establish simultaneously. This value indicates how many independent secure connections are supported for remote access, site‑to‑site links, or other encrypted communications.
