CRS112-8P-4S-IN

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. A 28V 3.4A power supply is already included in the box. There is a secondary DC jack on the back of the enclosure that supports a 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 a 48-57 V DC input is used (the 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
