• Passive PoE-Out through Ether5.
• USB 2.0 Type-A port with up to 1A output.
• 650MHz single-core QCA9531 CPU.
• 64MB RAM and 16MB Flash storage.
• RouterOS Level 4 license.
• Compact 113 × 89 × 28mm enclosure.
• Low maximum power consumption of approximately 5W.

2.4GHz Dual-Chain WiFi

The RB951Ui-2nD features a built-in 2.4GHz 802.11b/g/n dual-chain wireless radio. It is designed for basic wireless networking, internet access and local connectivity in homes and small offices.

The wireless interface supports a theoretical PHY rate of up to 300Mbps. Actual data throughput depends on channel conditions, interference, client capability, channel width and network configuration.

The integrated antennas provide approximately 1.5dBi gain with an omnidirectional 360° pattern.

5× 10/100 Ethernet Ports

The MikroTik hAP RB951Ui-2nD includes five individual 10/100 Mbps Ethernet ports. These ports can be configured through RouterOS for LAN connectivity, WAN access, VLANs, firewall policies and other networking functions.

It is important to note that the RB951Ui-2nD uses Fast Ethernet rather than Gigabit Ethernet. Therefore, it is best suited to deployments where 100Mbps Ethernet connectivity is sufficient.

Passive PoE-In and PoE-Out

Ether1 supports passive PoE-In, allowing the router to receive power through the Ethernet cable. The device also supports DC power through its power jack.

Ether5 provides passive PoE-Out for powering compatible RouterBOARD devices. MikroTik documentation specifies that the Ether5 output is approximately 2V below the input voltage and supports up to approximately 0.58A under the stated conditions. This is passive PoE, not IEEE 802.3af/at active PoE.

USB 2.0 Type-A Port

The integrated USB 2.0 Type-A port provides an additional expansion interface. The official specification lists up to 1A of USB output current.

Compatible USB peripherals can be used depending on RouterOS support and the specific deployment requirements.

650MHz QCA9531 Processor

The RB951Ui-2nD uses a QCA9531 single-core processor running at 650MHz, supported by 64MB RAM and 16MB Flash storage. This hardware platform is designed for the routing, firewall and wireless functions expected from this compact MikroTik router.

Because this is an older entry-level hardware platform with 10/100 Ethernet, it should be selected for basic networking requirements rather than high-speed Gigabit or multi-gigabit applications.

RouterOS Level 4

The hAP RB951Ui-2nD runs MikroTik RouterOS and includes a Level 4 license. RouterOS provides extensive configuration options beyond basic wireless routing.

• Internet gateway and NAT
• Firewall configuration
• DHCP server and client
• Static routing
• Wireless access point configuration
• Bandwidth management
• VLAN configuration
• VPN functionality
• Traffic monitoring
• Network administration through WinBox and other RouterOS tools

Compact Home and Small Office Design

The RB951Ui-2nD measures approximately 113 × 89 × 28mm, making it suitable for compact desktop or wall-mounted installations. Its small enclosure allows it to be deployed where space is limited.

The router supports an input voltage range of 6–30V DC according to the official product specification.

RB951Ui-2nD vs Gigabit MikroTik Routers

The RB951Ui-2nD is designed around 10/100 Mbps Ethernet, so it should not be confused with newer MikroTik routers featuring Gigabit Ethernet, WiFi 5 or WiFi 6. Its main advantages are its compact design, integrated 2.4GHz wireless, RouterOS functionality and passive PoE-Out capability.

For modern Gigabit networking, consider newer MikroTik platforms such as the MikroTik hEX Series or other current MikroTik routers.
