Description
MikroTik’s CRS112-8P-4S-IN is a Gigabit ethernet switch with eight PoE ports that offer different power output options: autosensing 802.3af/at PoE/PoE+ and Passive PoE.
There are also four SFP ports for optical fibre connectivity options which support uplinks of up to 1 Gbps.
The RS112-8P-4S-IN is equipped with 12 independent switching ports.
A 28V 3.4 A power supply is already included in the box and there is a secondary DC jack on the back of the enclosure that supports 48-57 V power supply (not included, can be purchased separately).
The 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.
