The MikroTik RB4011iGS+RM is a fanless 1U rackmount router built for professional and business network infrastructure. It combines ten 10/100/1000 Mbps Ethernet ports with a single 10 Gbps SFP+ uplink port, giving network engineers flexible connectivity options from the access layer through to high-speed fiber backbones. At its core is a quad-core AL21400 Cortex-A15 processor running at 1.4 GHz, backed by 1 GB of RAM and 512 MB of NAND storage, delivering the headroom needed for complex routing tables, firewall rule sets, and simultaneous VPN tunnels. Hardware-accelerated IPsec offloading keeps encrypted tunnel throughput high without burdening the CPU. The solid matte-black metal chassis operates entirely without a fan, making it well suited for noise-sensitive environments such as offices, studios, and compact data closets. Port 1 accepts passive PoE input (18–57 V) for flexible power sourcing, while port 10 provides passive PoE output at up to 57 V to power downstream devices. The unit ships with rackmount ears for tool-assisted installation in any standard 1U rack space. RouterOS Level 5 powers the software stack, enabling BGP, OSPF, RIP, VLANs, firewall, and a broad suite of VPN protocols including IPsec, L2TP, OpenVPN, and WireGuard. With a maximum draw of only 18 W without PoE out and 33 W with PoE out, the RB4011iGS+RM is an energy-efficient choice for always-on network roles.
Key features & benefits
- 10 Gigabit Ethernet Ports — Ten 10/100/1000 Mbps ports provide versatile wired connectivity for workstations, switches, access points, and other network devices across the enterprise edge or branch office.
- 10 Gbps SFP+ Uplink — A dedicated SFP+ port enables optional 10 Gbps fiber or direct-attach copper connectivity for high-throughput uplinks to core switches or ISP handoffs. SFP+ module sold separately.
- Quad-Core 1.4 GHz AL21400 CPU — The four-core Cortex-A15 processor at 1.4 GHz handles demanding routing, firewall, and VPN workloads simultaneously without throttling under sustained traffic loads.
- Hardware-Accelerated IPsec — Dedicated IPsec offload keeps encrypted site-to-site and remote-access VPN tunnels running at high throughput without exhausting CPU resources needed for other tasks.
- Fanless Metal Chassis — The all-metal enclosure uses passive cooling to eliminate fan noise entirely, improving reliability in environments where acoustic output and moving-part failure are concerns.
- Passive PoE In and Out — Port 1 accepts passive PoE input from 18–57 V for flexible power deployment. Port 10 delivers passive PoE output at up to 57 V to power a compatible downstream device without an additional injector.
- 1 GB RAM and 512 MB NAND Storage — Ample memory supports large routing and firewall tables, while onboard NAND storage holds the RouterOS installation and configuration without requiring external media.
- RouterOS Level 5 with Advanced Protocol Support — RouterOS Level 5 license unlocks BGP, OSPF, RIP, extensive VLAN management, firewall, and VPN protocols including IPsec, L2TP, OpenVPN, and WireGuard for comprehensive network control.
- Low Power Consumption — Maximum draw of 18 W without PoE out and 33 W with PoE out makes the unit economical for continuous 24/7 operation and keeps thermal output low in dense rack environments.
- Standard 1U Rackmount Form Factor — At 228 x 120 x 30 mm and supplied with rackmount ears, the RB4011iGS+RM installs cleanly in any standard 1U rack space alongside other infrastructure equipment.
