MikroTik CAOTS – Outdoor Case for Network Equipment Protection

MikroTik CAOTU is a plastic outdoor enclosure for protecting RouterBOARD equipment in exterior installations, compatible with the RB411, RB433, RB493 and RB800 series, designed for outdoor mounting where protection against weather, moisture and temperature variation is essential for network continuity. Commonly used in outdoor wireless installations, telecommunications towers and distribution points exposed to environmental conditions.

The enclosure includes an integrated Ethernet insulator that protects the equipment and network infrastructure against voltage surges and electrical discharges transmitted through the network cable — a critical requirement for any outdoor installation connected via a long Ethernet run. The included mounting set enables secure attachment to masts, walls or antenna brackets without additional purchases. The durable white plastic provides adequate mechanical protection for RouterBOARD units installed inside.

CAOTU is compatible with a wide range of RouterBOARD units across the RB411, RB433, RB493 and RB800 series, offering flexibility for various outdoor equipment configurations. The enclosure design maintains access to the ports and connectors of the installed board, simplifying maintenance interventions without full disassembly. The white color reduces solar heat absorption, helping to keep operating temperatures within safe limits in installations exposed to direct sunlight.

Recommended for outdoor wireless installations on towers and masts where RouterBOARD equipment requires full environmental protection, for access and distribution points exposed to weather conditions in ISP and enterprise networks, for any outdoor deployment where surge protection via the Ethernet insulator is a mandatory safety requirement, and for installation teams standardizing on enclosures compatible with multiple RouterBOARD models simultaneously.
