Planet WGS-4215-8T2S Przemysłowy 8-Portowy 10/100/1000T + 2-Porty 100/1000X SFP zarządzalny switch, montaż ścienny (-40~75 stopni C) Proste wdrożenie i rozbudowa sieci Zaprojektowany w obudowie ściennej do prostego montażu na ścianie lub w innym dogodnym miejscu, PLANET WGS-4215-8T2S jest inowacyjnym przemysłowym   8-Portowym 10/100/1000T + 2-Porty 100/1000X SFP, oferującym zarządzanie IPv6/IPv4.i nteligentne funkcje zarządzania wartswą 2 i przyjazny interfejs. WGS-4215-8T2S jest w stanie działać niezawodnie, stabilnie i cicho w każdym środowisku, bez wpływu na wydajność. Wyposażony w szybką sieć i możliwość pracy w szerokim zakresie temperatur od -40 do 75 stopni C , oraz wytrzymałą obudowę IP30, WGS-4215-8T2S jest idealnym rozwiązaniem w zastoswaniu: automatyka budynkowa/domowa internet rzeczy (IoT) Monitoring IP Sieć bezprzewowodowa Innowacyjne rozwiązanie ściennego montażu WGS-4215-8T2S został specjalnie zaprojektowany do instalacji gdzie mamy ograniczone miejsce na montaż jak np. skrzynka elektryczna. Pozwala na to kompaktowa, płaska konstrukcja ściennego. Zastosowanie przyjaznego "przedniego dostępu" pozwala na łatwy montaż okablowania i zapewnia znakomity dostęp dla techników. WGS-4215-8T2S możę by montowany ściennie za pomocą kołków, ściennie do metalowych powierzchni za pomoca dołączonych magnesów, oraz na szynie  DIN za pomocą dołączonego zestawu. Dzięki możliwości uniwersalnego montażu WGS-4215-8T2S ma szeroki zakres zastosowań. Możliwość podwójnego zasilania dla zapewnienia nieprzerwanego dostępu do sieci. WGS-4215-8T2S umozliwia wybór zasilania lub jednoczesne podwójne zasilanie (12V~48V DC lub 24V AC) dla zwiekszenia niezawodności systemu. W poniższym przykładzie, gdy blok zacisków 3-pin nie działa funkcja przełączania awaryjnego zostanie aktywowana automatycznie w celu utrzymania zasilania WGS-4215-8T2S. Alternatywnie WGS-4215-8T2S można zasilić poprzez wtyk DC co zapewni nieprzerwane działanie. Environmentally Hardened Design With IP30, flat but rugged metal housing protection, the WGS-4215-8T2S provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb side traffic control cabinets without air conditioner. Being able to operate under the temperature range from -40 to 75 degrees C, the WGS-4215-8T2S can be placed in almost any difficult environment. IPv6 / IPv4 Dual Stack Management Supporting both IPv6 and IPv4 protocols, the WGS-4215-8T2S helps the SMBs to step in the IPv6 era with the lowest investment as its network facilities need not be replaced or overhauled if the IPv6 FTTx edge network is set up. Robust Layer 2 Features The WGS-4215-8T2S can be programmed for advanced switch management functions such as dynamic port link aggregation, 802.1Q VLAN,  Q-in-Q VLAN, Multiple Spanning Tree Protocol (MSTP) , Loop and  BPDU Guard, IGMP Snooping , and  MLD Snooping . Via the link aggregation, the WGS-4215-8T2S allows the operation of a high-speed trunk to combine with multiple ports such as a 16Gbps fat pipe, and supports fail-over as well. Also, the  Link Layer Discovery Protocol (LLDP)  is the Layer 2 protocol included to help discover basic information about neighboring devices on the local broadcast domain. Efficient Traffic Control The WGS-4215-8T2S is loaded with robust QoS features and powerful traffic management to enhance services to business-class data, voice, and video solutions. The functionality includes broadcast/multicast/unicast  storm control , per port  bandwidth control , 802.1p/CoS/IP DSCP QoS priority and remarking.

Advanced Network Security PLANET WGS-4215-8T2S offers a comprehensive  IPv4/IPv6  Layer 2 to Layer 4  Access Control List (ACL)  for enforcing security to the edge. Its protection mechanism also comprises  802.1X port-based  user and device authentication, which can be deployed with RADIUS to ensure the port level security and block illegal users. With the  protected port  function, communication between edge ports can be prevented to guarantee user privacy. Furthermore, the WGS-4215-8T2S also provides  DHCP snooping ,  IP source guard  and  dynamic ARP inspection  functions to prevent IP snooping from attack and discarded ARP packets with invalid MAC address. The network administrators can now construct highly-secure corporate networks with considerably less time and effort than before. Flexibility and Long-distance Extension Solution The two mini-GBIC slots built in the WGS-4215-8T2S support SFP auto-detection and dual speed as it features  100BASE-FX  and  1000BASE-SX/LX SFP  (Small Form-factor Pluggable) fiber transceivers to uplink to backbone switch and monitoring center in long distance. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and up to 10/20/30/40/50/60/70/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions. Intelligent SFP Diagnosis Mechanism The WGS-4215-8T2S supports  SFP-DDM  ( Digital Diagnostic Monitor ) function that can easily monitor real-time parameters of the SFP for network administrator, such as optical output power, optical input power, temperature, laser bias current and transceiver supply voltage. Ready to Go with IoT Generation Internet is very popular the world over as users surf online daily with their mobile devices, such as smart phones, tablets, or laptop computers. However, users expect more from the convenience of Internet, like how to use their mobile devices to control something via the Internet, thus making life more convenient.
