Network switch MikroTik CRS418-8P-8G-2S+5axQ2axQ-RM — L2/L3, 17× Gigabit RJ-45, 2× SFP+, PoE (802.3af/at), 1U rack

The MikroTik CRS418-8P-8G-2S+5axQ2axQ-RM is a 1U rack-mount L2/L3 Ethernet switch designed for access-layer and aggregation deployments in small to medium enterprise networks. It provides seventeen Gigabit RJ‑45 ports including PoE output on selected ports, two SFP+ 10G uplink ports for high-speed fiber connections, and a dedicated console RJ‑45 port. The device supports IEEE 802.3af/at PoE standards, enabling centralized power delivery to access points, IP cameras and other PoE devices while offering basic L2/L3 switching features suitable for managed network environments.

Advantages

The CRS418-8P-8G-2S+5axQ2axQ-RM combines a compact 1U rack form factor with a mix of copper and 10G fiber connectivity, allowing flexible port placement and high-bandwidth uplinks in a single chassis. Built-in PoE output compatible with IEEE 802.3af and 802.3at simplifies installation of powered devices and reduces the need for separate power supplies at endpoints. The inclusion of SFP+ ports provides scalable uplink performance for aggregation to core switches or servers, and the console port supports local management and troubleshooting.

Suitable for

• Access layer switching in small to medium enterprise networks
• PoE device aggregation for access points, IP cameras and VoIP phones
• Edge or distribution switch with 10G uplinks to core infrastructure

Key specifications

• Form factor: 1U rack-mount
• Ethernet ports: 17 × Gigabit RJ‑45 (10/100/1000)
• Uplink ports: 2 × SFP+ (10G)
• PoE support: Output compliant with IEEE 802.3af and IEEE 802.3at
• Management: Console RJ‑45 port and software-based L2/L3 features

How to use

Install the switch in a standard 19" rack using the supplied mounting brackets and connect power according to the hardware manual. Connect access devices and endpoints to the Gigabit RJ‑45 ports and use the SFP+ ports for high-speed uplinks to aggregation or core switches. Configure VLANs, port modes and PoE settings through the device management interface to match your network design. Use the console RJ‑45 port for initial configuration or direct troubleshooting when needed.

Recommendations

Place the unit in a properly ventilated rack space and verify total PoE power budget before connecting multiple powered devices. Use quality SFP+ modules and fiber cabling for uplinks to achieve expected 10G performance. For deployments requiring advanced routing or heavy L3 processing, verify supported software features and offloading capability against your network requirements.
