MikroTik CRS112-8P-4S-IN

CRS112-8P-4S-IN is eight Gigabit RJ45 ports PoE switch, that offers different power output options: autosensing 802.3af/at PoE/PoE+ and Passive PoE, and four SFP ports provide optical fiber connectivity options to
support uplinks of up to 1 Gbps.
CRS112-8P-4S-IN is equipped with 12 independent switching ports. 28 V 3.4 A power supply is already included
in the box. There is secondary DC jack on the back of the enclosure that supports 48-57 V power supply (not
included, can be purchased separately). CRS112-8P-4S-IN can power 802.3af/at devices if 48-57 V DC input is
used (unit will automatically detect and provide correct power to devices). Max current is 1 A per port if input
voltage is 18-28 V, 450 mA if 48-57 V. Total limit is 2.8A@24V and 1.4A@48-57V.

Our CRS series combines a fully functional router and a managable switch with L3 features, it’s powered by
the familiar RouterOS. All the specific Switch configuration options are available in a special Switch menu, but
if you want, ports can be removed from the switch configuration, and used for routing purposes. It gives you all
the basic functionality for a managed switch, plus more: allows to manage port-to-port forwarding, apply MAC
filter, configure VLANs, mirror traffic, apply bandwidth limitation and even adjust some MAC and IP header
fields. IGMP snooping is also supported.
