MikroTik Cloud Router Switch 8 Port PoE 4SFP | CRS112-8P-4S-IN

Description

MikroTik's RB-CRS1128P is a Cloud Router Switch featuring 8x Gigabit PoE ports and 4x 1.25Gbps SFP ports. The 8 PoE ports support both passive PoE (with the included Power Supply) and 802.3af/at when powered by a 48-57V power supply. The unit is powered by RouterOS with a Level 5 License. Note: Both 24V and 48V PSU's can be used simultaneously to make use of both voltages for POE devices.

CRS112-8P-4S-IN

8x Gigabit Ethernet Smart Switch with PoE-out, 4x SFP cages, 400MHz CPU, 128MB RAM, desktop case, RouterOS L5

CRS112-8P-4S-IN is an eight Gigabit RJ45 port 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 - product codes 48POW (1.46A 70W) and 48V2A96W (2A 96W)). 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. PoE-Out is passed over mode B 4,5 (+) and 7,8 (-) pins
