Overview        NT-IN322BF series is an industrial-standard 4-port Gigabit switch with dual fiber port redundancy, providing 2-port 10/100/1000base-TX Ethernet ports and additional two 100/ 1000base-FX fiber ports. Rigorous industrial design makes it stable and reliable with basic protection, as well as flexible enough for Ethernet expansion in harsh industrial environments. When the main fiber broke down, NT-IN322BF can switch to redundant fiber within 1ms.   NT-IN322BF series is either rack-mountable with DIN rail or panel mounted in cabinet for easy installation. Wide range of working temperature, power supply backup, IP40 protection, LED indicators and compact design, all these make NT-IN322BF a perfect solution for special industrial application site.   NT-IN322BF-AT (AF) series is the POE version of NT-IN322BF with two POE Ethernet ports, powering POE IP camera, AP and IP phone over Ethernet cable. NT-IN322BF-AT (AF) supports IEEE802.3at with 25.5W output, compatible with IEEE802.3af.   Features * Dual fiber port redundancy available with DIP switch * Built-in efficient switching core to implement flow control and reduce broadcast packets * Protocol supported: IEE802.3 10base-T, IEEE802.3u 100base-TX/FX, IEEE802.3ab 1000base-T, IEEE802.3z  1000base-SX/LX, IEEE802.3x Flow Control, IEEE802.3at PSE * 10/100/1000base-TX can automatically identify the direct line and cross-line, is compatible with various cards,  switches, HUB and other Ethernet devices * Take store-and-forward mechanism to avoid packet loss and error frames * Provide four independent 10M/100Mbps/1000Mbps self-adaptive twisted pair ports; realize Ethernet port redundancy and multiple users access. * Support up to 1536 bytes packet. * Support full-duplex flow control / half-duplex back pressure mode * 12V--48V DC or 24V AC power supply input, redundant power and reverse polarity protection * -40 to 80℃ operating temperature to meet a variety of complex environment * IP40 standard protection housing. * Supports ESD protection at Ethernet port and EFT protection. * Easy installation, DIN rail or panel mountable. * Dual fiber multi mode, single mode and WDM single mode fiber compatible. * Support POE power supply up to 25.5W (optional) * 12 Gbps back plane bandwidth, 1 k MAC address automatic learning and 512kb internal cache for data buffer   Specification   Parameter Specification Design Level Industrial IP40 design standards Access mode 10/100/1000Mbps Protocols IEEE802.3 10base-T,IEEE802.3u 100base-TX,IEEE802.3ab 1000base-T, IEEE802.3z 1000base-SX/LX,IEEE802.3x Flow Control.IEEE802.3at PSE Wavelength 850nm/1310nm/1550nm Transmission distance Dual-fiber multi-mode:500m Single fiber single mode: 20/40/60/80/100km Dual-fiber single mode:20/40/60/80/100km Category-5 twisted pairs: 100m EIA 568A/B Port 2 RJ45 ports: Connecting STP/UTP category-5 twisted pairs, EIA568A/B 2 optical ports: Multi-mode :SC/FC/LC/ST(50/125, 62.5/125μm) Single mode : SC/FC/LC/ST (9/125μm) Conversion Store and Forward MAC 1K Buffer space 512Kb Flow control Full duplex: flow control; Half duplex: back pressure Time-delay Store and Forward: max. 9.6μs BER <10-9 MTBF 50,000 hours LED indicator Power Supply : PWR 1,PWR 2 POE at UTP port: POE1, POE2 Fiber Port: F1,F2 Power supply Power Input Range: 12 ~ 48VDC/24VAC , 6-PIN Terminals, Redundant dual power Power consumption <5W (without PSE function) Storage humidity 5%~90% non-condensing Operating humidity 5%~90% non-condensing Parameter Specification Operating temperature -40~80℃  Storage Temperature -40~80℃ Dimension 140mm(D)×110mm(W)×40mm(H) Weight         Certification EMI   FCC Part 15, CISPR (EN55022) class A EMC   FCC,CE EMS   EN61000-4-2 (ESD), Level 4   EN61000-4-3 (RS), Level 3   EN61000-4-4 (EFT), Level 4   EN61000-4-5 (Surge), Level 4   EN61000-4-6 (CS), Level 3   EN61000-4-8, Level 5   EN61000-4-11 Shock   IEC 60068-2-27 Free Fall   IEC 60068-2-32 Vibration   IEC 60068-2-6 Green product   RoHS Product picture http://www.nnetswitch.com
