MikroTik PoE Switch CRS112-8P-4S-IN | 8x Gigabit Ports with PoE-Out & 4x SFP Uplink Ports

MikroTik PoE Switch CRS112-8P-4S-IN | 8x Gigabit Ports with PoE-Out & 4x SFP Uplink Ports 8x Gigabit Ethernet Smart Switch with PoE-out, 4x SFP cages, 400MHz CPU, 128MB RAM, desktop case, RouterOS L5 MikroTik PoE Switch 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. The CRS112-8P-4S-IN features 12 independent switching ports. It comes with a 28V 3.4A power supply included in the box. You can also use the secondary DC jack on the back, which supports a 48–57V power supply (not included). Compatible power supplies include models like 48POW (1.46A, 70W) and 48V2A96W (2A, 96W). When powered via 48–57V DC, the switch can automatically detect and power 802.3af/at devices. The maximum output current per port is 1A at 18–28V input and 450mA at 48–57V input. The total PoE output limit is 2.8A at 24V or 1.4A at 48–57V. The PoE-out power is delivered via Mode B on pins 4,5 (+) and 7,8 (–).
