MikroTik's RB-CRS1128P is an eight port Gigabit PoE switch, that offers different power output options: autosensing 802.3af/at PoE/PoE+ and Passive PoE, and four SFP ports provide optical fibre connectivity options to support uplinks of up to 1 Gbps.
The RB-CRS1128P is equipped with 12 independent switching ports. 28V 3.4A power supply is already included in the box. There is a secondary DC jack on the back of the enclosure that supports 48-57V power supply (not included).
The RB-CRS1128P can power 802.3af/at devices if 48-57V DC input is used (unit will automatically detect and provide correct power to devices). The maximum current is 1A per port if the input voltage is 18-28V, 450mA if 48-57V. Total limit is 2.8A@24V and 1.4A@48-57V.
