## Description

CRS112-8P-4S-IN is an eight Gigabit RJ45 port PoE switch, that offers different power output options: autosensing 802.3af/at PoE/PoE+ and Passive PoE, and four SFP ports provide optical fiber connectivity options to support uplinks of up to 1 Gbps. CRS112-8P-4S-IN is equipped with 12 independent switching ports. 28 V 3.4 A power supply is already included in the box. There is secondary DC jack on the back of the enclosure that supports 48-57 V power supply (not included, can be purchased separately). CRS112-8P-4S-IN can power 802.3af/at devices if 48-57 V DC input is used (unit will automatically detect and provide correct power to devices). Max current is 1 A per port if input voltage is 18-28 V, 450 mA if 48-57 V. Total limit is 2.8A@24V and 1.4A@48-57V. PoE-Out is passed over mode B 4,5 (+) and 7,8 (-) pins

Review: Great little power house if you need a router and an 8 port POE switch. It's not for a none Mikrotik users. It is not a plug and play unit. You must know about Mikrotiks and how to configure them.
Review: No venía el soporte para montarse en rack, no lo devuelvo porque me es funcional y me urge pero he notado que últimamente las piezas pequeñas de ciertos pedidos no las envian

### ⭐⭐⭐⭐⭐ Review
*by R***L on 4 October 2025*

Zugegebenermaßen für Neulinge mit RouterOS etwas tricky in der Konfiguration, aber mehr Leistung für Ihr Geld wird man in diesem Leistungssegment kaum finden. Bei diesem Produkt kann man eigentlich kaum etwas falsch machen. Auch die Verarbeitung auf hohem Niveau - nix Billig-Plastik :) Aber bitte bedenken: Konfiguration setzt recht steile Lernkurve voraus!
