CRS112-8P-4S-IN: 8x Gigabit Ethernet Smart Switch with PoE-out, 400MHz CPU, 128MB RAM, desktop version with rack mount accessory, RouterOS L5

CRS112-8P-4S-IN is a PoE switch with eight Gigabit RJ45 ports, offering various power output options: autosensing 802.3af/at PoE/PoE+ and Passive PoE, and four SFP ports provide fiber optic connectivity options to support uplinks up to 1 Gbps.

CRS112-8P-4S-IN is equipped with 12 independent switching ports. The 28 V 3.4 A power supply is already included in the box. There is a secondary DC jack on the back of the enclosure that supports 48-57 V power (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 a 48-57 V DC input is used (the unit will automatically detect and provide the correct power to the devices). The maximum current is 1 A per port if the input voltage is 18-28 V, 450 mA if 48-57 V. The total limit is 2.8A@24V and 1.4A@48-57V. PoE-Out is passed on pins 4,5 (+) and 7,8 (-) of mode B
