NETGEAR GS752TP Switch Niv.2 48 ports Gigabit PoE + 4 SFP 512W

Product Information

Network Management System (NMS300), allowing all NETGEAR business products to be deployed and managed through this single interface Dedicated SFPs, not only providing fiber uplinks, but also uplink redundancy and failover, improving reliability and availability for the network

Advanced QoS (Quality of Service) for traffic prioritization including port-based, 802.1p and L2/L3/L4 DSCP-based Facilitate fast receiver joins and leaves for multicast streams. Save cost and improve network efficiency by ensuring multicast traffic only reaches designated receivers without the need of an extra multicast router. E' uno switch amministrabile, cioè è possibile programmarne il funzionamento attivando per esempio le VLAN, l'aggregazione di link, alcuni meccanismi di protezione L2. Se non fate nulla, funziona come switch "normale". Questa programmazione viene fatta via WEB, ma non è una cosa alla portata di tuttiThe NETGEAR® new generation Gigabit 52 port (48 port copper + 4 port fibre) PoE Smart Switch offers powerful L2 features, better PoE functions, and enhanced performance and usability. The GS752TP come with PoE capabilities on all ports, providing hardware investment protections so that the switch can support many more PoE powered devices and new higher-powered devices down the road. It is purposely designed for the converged networks where voice, video, data are all carried on a single network platform for network efficiency, operational cost savings, and ease of management.

Insert a straightened paper clip or a similar device into the hole of the Factory Default button and hold for two to three seconds. These eight port PoE + two fibre uplinks (you'll need SFP+ modules to use them) switches are a great choice for the more advanced home network or office setup. They are ideal for powering IP cameras, phones, wifi access points and other such devices. If you press the Factory Default button too long, some switches change to recovery mode, signified by the LED light turning from green to amber. If this happens, power cycle the switch or press the Reset button to reboot the device.

Documentation:

IP phones and PCs can authenticate on the same port but under different VLAN assignment policies. Users are free to move around and enjoy the same level of network access regardless of their physical location on the network. Four dedicated Gigabit SFP ports for aggregation to the network core. Support for fibre and Copper modules. Can also build dual redundancy by a trunked uplink with link aggregation and failover. Ha due slot per inserire moduli SFP per le fibre ottiche, da comprare a parte (questa caratteristica non l'ho ancora testate: a casa non ho una rete in fibra)

Comprehensive IPv6 supporting management, QoS and ACL, ensuring investment protection and a smooth migration to IPv6-based network Support high-density VoIP, Surveillance and Wi-Fi AP deployments, scalable for future growth. Never face the risk of running out of PoE ports. Advanced controls for optimized network performance and better delivery of mission-critical traffic such as voice and video. It's quiet, switches data fast and works well, as long as you do your research first about VLANS and Trunking and design your network. The management interface isn't very fast, but after initial setup you only need to tweak stuff here and there. Temperature-based fan-speed control minimises system acoustic noise in any environment starting at 27.08dB at 25°C (77°F) ambient.Temperature-based fan-speed control minimizes system acoustic noise in any environment starting at 27.08dB at 25°C (77°F) ambient.

Es ideal para sistemas domoticos, ya que permite activar y desactivar el POE de los puertos a traves del interfaz web, o desde linea de comandos (tiene un interfaz al que puedes acceder haciendo telnet al puerto 60000, poniendo el usuario, la contraseña y despues entrando en el modo administrativo con el comando enable (y con la contraseña en blanco)). El funcionamiento de Interfaz de comandos (CLI) es muy parecedo al de los dispositivos Cisco (ver imagen). Otra cosa buena que tiene es que es muy poco profundo, lo cual lo hace ideal para poner en una balda dentro de un armario de 20cm de profundidad (no se fuerzan los conectores rj45 en el frontal como sucede con otros switches mas profundos).Build current network with future in mind. Ensure investment protection and a smooth migration to an IPv6-based network without switch replacement. Additional Insight managed devices added to the network automatically inherit the network configuration Da tempo uso switch Netgear, ne apprezzo quindi la struttura generale, la "robustezza" elettrica e meccanica rispetto ad altre marche, il costo ragionevole, l'aggiornamento del firmware garantito anche a distanza di anni. Questo non mi sembra faccia eccezione, anche se lo sto usando solo da un paio di pomeriggi.
