Description 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 Specifications Details Product code CRS112-8P-4S-IN Architecture MIPSBE CPU QCA8511 CPU core count 1 CPU nominal frequency 400 MHz Switch chip model QCA8511 Dimensions 200 x 142 x 44 mm RouterOS license 5 Operating System RouterOS Size of RAM 128 MB Storage size 16 MB Storage type FLASH MTBF Approximately 200’000 hours at 25C Tested ambient temperature -20°C to 60°C Suggested price $209.00 Powering Details Number of DC inputs 2 (DC jack) DC jack input Voltage 18-28 V / 48-57 V Max power consumption 160 W Max power consumption without attachments 10 W Cooling type Passive PoE-out Details PoE-out ports Ether1-Ether8 PoE out 802.3af/at Low voltage PoE-Out current limit 1 A High voltage PoE-Out current limit 450 mA Max total out (A) 2.8A (18V-28V) & 1.4A (48V-57V) A Ethernet Details 10/100/1000 Ethernet ports 8 Number of 1G Ethernet ports with PoE-out 8 Fiber Details SFP ports 4
