CRS112-8P-4S-IN

The CRS112-8P-4S-IN is an eight-port Gigabit PoE switch with four SFP ports for high-speed fiber uplinks. It offers flexible power output options, supporting auto-sensing 802.3af/at PoE/PoE+ as well as Passive PoE.

This device features a total of 12 independent switching ports. The included 28 V 3.4 A power supply covers most scenarios, while an additional DC jack on the back supports 48-57 V input (not included). When using 48-57 V, the unit can automatically detect and power 802.3af/at devices. The max current per port is 1 A at 18–28 V or 450 mA at 48–57 V, with a total power limit of 2.8 A @ 24 V and 1.4 A @ 48–57 V.

The CRS series blends the features of a fully functional router with the power of a managed switch. Running on MikroTik’s RouterOS with a Level 5 license, it includes an easy-to-use Switch menu for Layer 2 functions, while advanced users can reassign ports for routing as needed. You’ll find all the essentials for a managed switch, plus advanced features like port forwarding control, VLANs, MAC filtering, traffic mirroring, bandwidth control, and more.
