MikroTik CRS112-8P-4S-IN
CRS112-8P-4S-IN is an eight Gigabit RJ45 port PoE switch with autosensing 802.3af/at PoE/PoE+ and Passive PoE power output options, and four SFP ports enable optical fiber connectivity options to handle uplinks of up to 1 Gbps.
The CRS112-8P-4S-IN has 12 independent switching ports. The power supply (28 V 3.4 A) is already included in the package. On the back of the enclosure, there is a secondary DC connection that supports a 48-57 V power supply (not included, but available separately - product codes 48POW (1.46A 70W) and 48V2A96W (2A 96W)). If a 48-57 V DC input is used, the CRS112-8P-4S-IN can power 802.3af/at devices (the unit will automatically detect and provide correct power to devices). The maximum current per port is 1 A when the input voltage is 18-28 V and 450 mA when the input voltage is 48-57 V. The total current limit is 2.8A@24V and 1.4A@48-57V. PoE-Out is routed using mode B's 4,5 (+) and 7,8 (-) pins.
