Your Network, Your Rules: Maximum PoE Flexibility
Forget rigid PoE solutions! The MikroTik CRS112-8P-4S-IN is the true PoE chameleon for your Network. Its eight Gigabit Ethernet RJ45 PoE Switch ports are equipped with an intelligent auto-sensing function that automatically detects which PoE standard your connected device requires. Whether you want to power a MikroTik SXT Antenna with 24V or an 802.3af/at PoE+ IP camera, this PoE Switch reliably and correctly supplies them with power – all from a single device. The special feature: thanks to the dual Power Supply (18-28V and 48-57V DC input), you can flexibly adjust the PoE budget and supported standards. This allows you to power 24V passive devices and 48V 802.3af/at PoE+ devices simultaneously if you purchase the corresponding 48-57V Power Supply separately. That's flexibility that competitors often overlook!
High-Speed Connectivity with Fiber Optic Power
Data transmission bottlenecks are a thing of the past. The MikroTik CRS112-8P-4S-IN offers four SFP Ports that enable lightning-fast Fiber Optic Connectivity. Achieve uplinks of up to 1 Gbit/s and effortlessly connect the Managed Switch to your backbone Network, core switches, or bridge longer distances where copper cables reach their limits. Ideal for connecting high-resolution cameras or expanding your Network in larger environments. These SFP Ports are a real game-changer for your network infrastructure.
Full Control with RouterOS: Your Managed Switch for Professionals
As a Managed Switch with Layer 2 Switching and Layer 3 Routing functions, powered by the powerful RouterOS Level 5 license, the MikroTik CRS112-8P-4S-IN gives you full control over your Network. Configure detailed VLAN Support, use port isolation, set ACLs, or monitor traffic – all via an intuitive interface. The special thing about RouterOS: you can remove ports from the switch configuration and use them for routing purposes. This fine-grained control goes far beyond the capabilities of many pure Layer 2 Switching devices and makes the CRS112-8P-4S-IN a true power tool for your Network Infrastructure. Discover the diversity of Network Network and optimize your infrastructure.
Silent, Robust, and Versatile: At Home Everywhere
Are you looking for an Ethernet Switch that is not only powerful but also discreet? The MikroTik CRS112-8P-4S-IN is a Fanless Design PoE Switch and operates absolutely silently. This makes it perfect for offices, hotels, or living areas where noise would be disruptive. But that's not all: it is designed for a wide temperature range from -20°C to 60°C. This allows you to use it in demanding environments such as control cabinets or warehouses, where other MikroTik Switches would long give up. A truly compact Desktop/Rackmount PoE Switch that delivers on its promises and seamlessly integrates into any environment.
Strengths & Notes at a Glance
- Pro: Versatile PoE Support: The switch offers autosensing 802.3af/at PoE+ and Passive PoE on all 8 Gigabit Ethernet ports, enabling Power Supply to a wide range of devices such as IP Cameras, WLAN access points, and VoIP phones via a single cable.
- Pro: Flexible Connectivity with SFP Ports: Four SFP Ports enable Fiber Optic Connectivity uplinks of up to 1 Gbit/s, which is ideal for connecting to backbone networks, core switches, or for longer distances where copper cables reach their limits.
- Pro: RouterOS Functionality and Management: With RouterOS Level 5, the Managed Switch combines powerful Layer 2 Switching functions with basic Layer 3 Routing capabilities, firewalling, and advanced management options that allow for detailed network configuration and monitoring.
- Note: Limited PoE Budget for 802.3af/at without Separate Power Supply: Although a 28V 3.4A power supply is included, a separate 48-57V power supply is required for full 802.3af/at PoE+ functionality and a higher PoE budget (up to 160W). The included power supply primarily supports passive 24V PoE or a lower budget for 802.3af/at PoE+.
- Note: Limited Layer 3 Routing Performance: Although the device supports Layer 3 Routing functions and runs with RouterOS, the CPU (400 MHz) is not optimized for demanding routing tasks or high throughput in Layer 3 mode. It is primarily designed as a Managed Switch with L3 features and should be used for pure Layer 2 Switching applications or basic routing.

Frequently Asked Questions (FAQ)
What is the main purpose of the MikroTik CRS112-8P-4S-IN?
The MikroTik CRS112-8P-4S-IN is a Cloud Router Switch that combines the functions of an 8-port Gigabit PoE switch and a router with 4 SFP ports for fiber uplinks. It serves to power your network devices and transmit data over copper and fiber optic cables.
Which PoE standards does the CRS112-8P-4S-IN support?
The switch supports both the common 802.3af/at (PoE/PoE+) standards and Passive PoE. It can automatically detect the required power type when you use a 48-57V DC input voltage.
Can the MikroTik CRS112-8P-4S-IN also be used as a router?
Yes, the device runs MikroTik's RouterOS and combines the functions of a fully functional router with those of a manageable switch with Layer 3 features. You can remove ports from the switch configuration and use them for routing purposes, however, the routing performance is limited for demanding scenarios.
Is the CRS112-8P-4S-IN fanless and therefore quiet?
Yes, the MikroTik CRS112-8P-4S-IN features a passive cooling system and is fanless, allowing for silent operation.
Which power supply is included and what impact does it have on PoE?
A 28V 3.4A power supply is included. With this power supply, the switch can deliver Passive PoE with up to 1A per port. For full 802.3af/at support and higher PoE performance, you will need a separate 48-57V power supply (not included).
What kind of management features does the switch offer?
The switch offers extensive Layer 2 management features such as VLAN (IEEE 802.1Q, up to 4000 VLANs), Port Isolation, Port Security, Broadcast Storm Control, Port Mirroring, Rapid Spanning Tree Protocol (RSTP), Access Control Lists (ACLs), IGMP Snooping, and Static Link Aggregation.
