The CRS112-8P-4S-IN is an 8-port Gigabit PoE switch that offers a variety of power options: automatic 802.3af/at PoE/PoE+ detection and passive PoE and four SFP ports offer fiber optic connectivity options to connect to uplinks up to 1 Gbps.
The CRS112-8P-4S-IN is equipped with 12 independent switching ports. 28 V 3.4 The power supply is already included in the set. On the back of the enclosure there is an additional DC socket, which supports 48-57 V power supply (not included in the set, can be purchased separately - product codes 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 device will automatically detect and ensure correct power supply to the devices). The maximum current is 1 A per port if the input voltage is 18-28 V, 450 mA if 48-57 V. The total limit is 2.8A@24V and 1.4A@48-57V. PoE-Out is transmitted via the B-mode 4.5 (+) and 7.8 (-) contacts.
The product is equipped with the highest class operating system RouterOS with level 5 license, allowing the user to access almost infinite configuration possibilities.

CAPsMAN is a tool created by MikroTik to manage access points, thanks to the use of profiles it ensures ease of network expansion. Before you start working with this tool, you should make sure that the same version of MikroTikOS software and the same "wireless" package is installed on each of the devices, both router and access points.
A switch is a device that connects segments of a computer network.
There is no winner between Mikrotik and Ubiquiti Networks, none of them is better or worse, there are different tasks and problems and different solutions for them. Choose a product according to your needs, not your brand.
