MikroTik's RB-CRS1128P is a compact Cloud Router Switch equipped with 8x Gigabit PoE ports and 4x 1.25Gbps SFP ports for fiber connectivity. The eight Ethernet ports deliver highly flexible power management, providing Passive PoE right out of the box using the included power supply, or standard 802.3af/at PoE when connected to an external 48–57V source. Running on a fully unlocked RouterOS Level 5 License, this device offers deep routing and switching capabilities. Note: You can connect both 24V and 52V power supplies simultaneously, allowing the switch to dynamically output both voltages depending on what your connected PoE devices require.
