Mikrotik CRS112-8P-4S-IN | 8 Ports Gigabit Ethernet PoE Cloud Router Smart Switch (with PoE out)

Description

Key Features

Connectivity & Ports

• 8 × Gigabit RJ45 Ethernet ports with PoE-out support, capable of delivering power directly to connected devices such as IP cameras, VoIP phones, or access points.

• 4 × 1 Gbps SFP cages for fiber uplinks or long-distance network links.

• 1 × RJ45 serial (console) port for local management and diagnostics.

PoE Power and Flexibility

• Supports autosensing 802.3af/at PoE/PoE+ and Passive PoE output.

• Power can be supplied through dual DC jacks (18–28 V or 48–57 V), with auto-detection to correctly provide PoE to devices.

• Per-port PoE current up to 1 A at 18–28 V or 450 mA at 48–57 V; total PoE budget varies based on input, ensuring flexibility for powering multiple devices.

RouterOS Management

• Runs RouterOS with Level 5 license, offering advanced management features including VLANs, traffic control, ACLs, port isolation, STP/RSTP, SNMP, and more.

• Provides layer-2 and some layer-3 functionality—allowing bridges, routing, VLAN tagging, and QoS configurations for complex network environments.

Performance & Hardware

• Powered by a 400 MHz single-core CPU with 128 MB RAM and 16 MB flash storage.

• Offers non-blocking layer-2 switching performance with ~24 Gbps switching capacity and up to 17.8 Mpps forwarding rate.

• Passive cooling (fanless design) ensures quiet operation and reliability.

Build & Installation

• Compact desktop or partial rackmount form factor with included mounting accessories.

• Operating temperature range suitable for indoor network environments.

• Includes a 28 V 3.4 A power adapter in the box.

Ideal Use Cases

• Small business networks needing managed switching with PoE for surveillance cameras, phones, or APs.

• Fiber uplinks or connections to central switches/routers via SFP modules.

• Networks requiring advanced VLANs, traffic policies, and monitoring via RouterOS.
