Professional networking equipment — MikroTik's managed L3 Cloud Router Switch, model CRS112-8P-4S-IN. The device is equipped with 8x Gigabit (10/100/1000 Mbps) Ethernet ports and 4x SFP (1.25G) optical cages. Its primary advantage is the PoE-out functionality on all eight Ethernet ports (supporting auto-sensing 802.3af/at and Passive PoE). It is an ideal solution for powering and managing IP cameras, wireless Access Points, and VoIP phones. Powered by the RouterOS (Level 5) system, it provides full routing capabilities alongside advanced switching features. The device comes in a compact desktop metallic enclosure (the package includes brackets for standard 1U rackmount installation).
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 - product codes 48POW (1.46A 70W) and 48V2A96W (2A 96W)). 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
