MikroTik CRS504-4XQ-OUT Outdoor 4-Port 100G QSFP28 Network Switch IP66

The MikroTik CRS504-4XQ-OUT is a compact, energy-efficient outdoor switch engineered to deliver 100 Gbps switching performance in demanding outdoor environments. Built around the Marvell Prestera switch chip and housed in an IP66-rated weatherproof enclosure, it provides four QSFP28 ports that support 100G, 40G, 25G, 10G, and 1G connections — expandable to up to 16 fiber interfaces via breakout cables. A QCA9531 650 MHz MIPSBE CPU with 128 MB RAM and 32 MB Flash handles management, while robust feature support including VLANs, ACL, MLAG, Jumbo frames, and L3 hardware offloading makes it well-suited for ISP deployments, outdoor events, and any application requiring high-throughput, weatherproof network infrastructure. Three flexible powering options — 802.3bt PoE-in, DC jack, and 2-pin terminal — allow straightforward integration into a wide range of field installations.

Key features & benefits

• 4x QSFP28 100G Ports — Four QSFP28 ports deliver up to 100 Gbps per interface and support backward compatibility with 40G, 25G, 10G, and 1G connections, providing the flexibility to integrate with existing fiber infrastructure at multiple speed tiers.
• Up to 16 Fiber Interfaces via Breakout — Using breakout cables, each QSFP28 port can be split into multiple lower-speed interfaces, expanding the switch to up to 16 high-speed fiber connections from a single compact chassis.
• IP66 Weatherproof Enclosure — The IP66-rated enclosure protects internal electronics against powerful water jets and environmental ingress, enabling reliable continuous operation in outdoor locations regardless of weather conditions.
• Marvell Prestera Switch Chip — The Marvell Prestera switching silicon provides hardware-level support for VLANs, ACL, MLAG, Jumbo frames, and L3 hardware offloading, enabling enterprise-grade traffic management at the edge without sacrificing efficiency.
• Three Flexible Powering Options — Supports 802.3bt PoE-in (43–57 V), a DC jack (36–57 V), and a 2-pin terminal (36–57 V), giving installers multiple options to power the unit cleanly in varied field environments.
• Wide Operating Temperature Range — Rated for operation from -40°C to +70°C, the CRS504-4XQ-OUT maintains full functionality through extreme cold and heat, making it suitable for year-round outdoor deployments across diverse climates.
• Low Maximum Power Consumption — Draws only 25W without attachments and a maximum of 38W under full load, keeping operating costs and thermal output low relative to the switching capacity delivered.
• Onboard Management CPU — A QCA9531 650 MHz MIPSBE processor paired with 128 MB RAM and 32 MB Flash storage handles switch management tasks independently, supporting consistent and reliable device administration.
