The MikroTik CRS112-8P-4S-IN is a Gigabit ethernet switch that features eight PoE ports with different power options: autosensing 802.3af/at PoE/PoE+ and Passive PoE. It also includes four SFP ports for optical fiber that support uplinks up to 1 Gbps. The CRS112-8P-4S-IN is equipped with 12 independent switching ports. The package includes a 28V 3.4 A power supply and there is a secondary DC input on the back of the case that supports 48-57 V power (not included, can be purchased separately). The CRS112-8P-4S-IN can power 802.3af/at devices if a 48-57 V DC input is used (the unit will detect and provide the correct power). The maximum current is 1 A per port if the variable voltage is 18-28 V and 450 mA if it is 48-57 V. The total limit is 2.8A@24V and 1.4A@48-57V.
