Netgear GS748T 48-Port Smart GIGABIT Switch with 4 SFP ports
Overview
Switches with Essential L2 Features for SMB Networks
NETGEAR Smart Managed Switches offer powerful L2 and L2+/Layer 3 Lite features, better PoE functionality, and enhanced performance and usability. They are purposely designed for converged networks where voice, video, data are all carried on a single network platform. These switches are optimized for network efficiency, operational cost savings, and ease of management. This series of switches offers 8 to 52 port configurations both in Fast Ethernet and Gigabit Ethernet with PoE options. All switches come with Gigabit SFP ports for fiber connectivity. These switches are the ideal solution for businesses looking for the best combination of features, performance, and value.
Designed for Converged Networks, Big or Small
- PoE and PoE+ Support available for all configurations
- Auto Voice VLAN for fast and reliable deployment of VoIP
- Auto Video VLAN, following the same concept of Auto Voice, help speed up your deployment of IP-based surveillance systems
- Static routing, helps route internal traffic for more efficient use of network resources
- IGMP and MLD snooping, provides advanced multicast filtering
Build a Future-Proof Network with NETGEAR
- Solid performance with a non-blocking architecture, 8K MAC address table, 256 VLANs, 480 shared ACL entries, 32static routes, and 1,024 Multicast Groups
- Comprehensive IPv6 management, QoS and ACL, ensuring investment protection and a smooth migration to IPv6-based networking
- PoE+ support on all PoE models with the GS728TPP providing PoE+ support on all ports, adding the flexibility to add power-hungry devices such as video phone, PTZ camera and 11ac Wireless APs into the network in the future
- The presence of SFP ports provide necessary fiber uplinks, while dedicated SFP ports on many models further builds uplink redundancy and failover, improving reliability and availability for network virtualization
- Energy Efficient Ethernet (IEEE802.3az) support for more energy savings in the future when more EEE-compliant end devices come to market
- Advanced QoS with IPv4/IPv6 ingress traffic filtering (ACLs) and prioritization (QoS – Diff Serv)
- Dynamic VLAN assignment for easy user authentication and location-independent access to network
Network Development Made Easy
- Auto Voice VLAN for easy development of VoIP
- Auto Video for simple deployment of IP Surveillance
- ACL Wizard for a guided tour to set up your network access control
- Smart Control Center, a powerful tool for multi-switch discovery, deployment, monitoring and firmware upgrades
- PoE Timer for scheduling the on/off time of your PoE powered devices
Smart IT, not Big IT
- Easy to manage via web-Based Management GUI or Smart Control Center for multi-switch deployment
- Standard-based technology, ensuring interoperability with any standard-based devices in the existing network
- Dual firmware images, improving reliability and uptime to your network
