CRS112-8P-4S-IN is a PoE switch with 8 Gigabit ports, which offers different power output options: autosensing 802.3af/at, PoE/PoE+ and Passive PoE, and the 4 SFP ports offer optical fiber connection options for uplink links up to 1 Gbps. It comes with a 28V 3.4A adapter included in the box. There is also a secondary DC jack on the back of the case that accepts a 48-57V power supply that must be purchased separately (models 48POW (1.46A 70W) and 48V2A96W (2A 96W)). The CRS112-8P-4S-IN can power 802.3af/at devices if the 48-57V DC input is used (the unit will automatically detect and supply the correct power to the devices). The maximum current is 1A per port. The total limit is 2.8A@24V and 1.4A@48-57V.
