Description:CRS112-8P-4S-IN is an eight Gigabit RJ45 port PoE switch, that offersdifferent power output options: autosensing 802.3af/at PoE/PoE andPassive PoE, and four SFP ports provide optical fiber connectivityoptions to support uplinks of up to 1 Gbps.CRS112-8P-4S-IN is equipped with 12 independent switching ports. 28 V3.4 A power supply is already included in the box. There is secondaryDC 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 power802.3af/at devices if 48-57 V DC input is used (unit will automaticallydetect and provide correct power to devices). Max current is 1 A perport if input voltage is 18-28 V, 450 mA if 48-57 V. Total limit is2.8A@24V and 1.4A@48-57V. PoE-Out is passed over mode B 4,5 ( ) and 7,8(-) pinsSpecificationsDetailsProduct code CRS112-8P-4S-INArchitecture MIPSBECPU QCA8511CPU core count 1CPU nominal frequency 400 MHzLicense level 5Size of RAM 128 MBStorage size 16 MBStorage type FLASHPoweringDetailsMax Power consumption 10WPoE out 802.3af/atNumber of DC inputs 2 (DC jack)DC jack input Voltage 18 – 57 VEthernetDetails10/100/1000 Ethernet ports 8FiberDetailsSFP ports 4PeripheralsDetailsSerial port RJ45OtherDetailsPCB temperature monitor Yes
