516S8C4M
The SIL 516S8C4M is a rack-mountable Layer 3 Managed Network Switch engineered for demanding industrial and utility-grade applications.
The SIL 516S8C4M is a rack-mountable Layer 3 Managed Network Switch engineered for demanding industrial and utility-grade applications. Its efficient Top-of-Rack form factor ensures optimal use of space within rack cabinets, making it ideal for enterprise networks, intelligent transportation systems (ITS), and utility infrastructure. This model provides a versatile port configuration, including: 16 × Gigabit SFP Downlink Ports 8 × RJ45 + SFP Combo Ports 4 × 10Gb SFP Uplink Ports Designed with a fanless architecture, the switch relies on natural convection cooling. This enhances long-term reliability, reduces maintenance requirements, and allows more of the system’s power budget to be allocated to processing and switching performance. Powered via a 240 VAC IEC input, the SIL 516S8C4M integrates seamlessly into commercial and industrial power environments without the need for external DC power supplies, simplifying installation and reducing cabinet complexity. Built for environments where space optimisation, resilience, and interconnectivity are critical, this switch performs reliably in unconditioned outdoor cabinets, roadside enclosures, and industrial control rooms. Its extended operating temperature range and robust metal enclosure ensure dependable operation in harsh conditions. The SIL 516S8C4M adheres to key industry standards including IEEE 802.3, 802.3u, 802.3z, 802.3ab, 802.3x, 802.3az, 802.3ah, as well as IEEE 802.1X and 802.1Q, ensuring compatibility with modern industrial Ethernet architectures.
