Netgear GS748TPS - PROSAFE® 48-PORT GIGABIT STACKABLE POE SMART SWITCH GS748TPS

• The industry's first Gigabit Smart Switch with both PoE and Stacking
• The industry's first to support PoE Plus on Smart switch platform
• True Stacking for flexibility, scalability and easy network management

Powerful Gigabit Smart Switches Supporting both Stacking and PoE

The ProSafe™ Gigabit Stackable Smart PoE (Power over Ethernet) Switches are specifically designed for growing small and mid-sized businesses (SMB) with advanced network needs for the support of multiple "new-world" applications: Voice over IP (VoIP), a unified wired/wireless network, IP surveillance, converged video and data network and much more. It delivers the scalability, flexibility, reliability, and performance the SMB customers need in an affordable and easy-to-manage package.

Each ProSafe™ Gigabit Stackable Smart PoE Switch comes with 48 10/100/1000 Mbps ports and four shared SFP ports. All ports support standards-based PoE and as a first in the industry, they also support IEEE 802.3at-based PoE+ on the first 4 ports of each switch, capable of providing up to 30W of power to higher-powered PoE devices such as dual-band N Wireless access points, videophones and IP cameras with pan/tilt/zoom capabilities. Coupled with autovoice VLAN feature, the switch greatly reduces the complexity of VoIP deployment, and makes it easy for SMBs to implement and manage a VoIP system on their network.

The stacking feature on these switches provides the SMB with uncompromised performance, scalability and ease of network management. The only Gigabit Smart Stackable switches in the industry, they can be stacked through dedicated high-speed stacking ports (HDMI-based) with an aggregate 20 Gbps bandwidth, ensuring that the traffic between the stacked switches won't be compromised. Customers can scale up to 6 switches in one stack, and all of them can be easily configured and managed as one switch. Businesses can add switches to the stack as their network expands without making a big upfront investment at the beginning. Meanwhile, the stack's redundancy and hot-swappable capability help boost network resiliency. Under the same Gigabit Stackable Smart Switch family, the GS724TPS and GS748TPS switches can be stacked together with GS724TS and GS748TS.

These switches come with a complete suite of advanced features such as access control lists (ACL), 802.1x port authentication, enhanced QoS, rate limiting and IGMP snooping, among others, to provide SMB businesses with more robust security, higher quality of service and high availability.

An intuitive, Web browser interface provides simple yet comprehensive management, making it extremely simple to deploy and manage the advanced features, in order to realize the potential of a converged network and deliver lower total cost of ownership.

Scalability and High Availability

Each ProSafe™ Gigabit Stackable Smart PoE Switch comes with 2 dedicated high-speed stacking ports on the rear of the switch providing 20 Gbps of bandwidth, allowing you to stack up to six switches or 288 10/100/1000 Mbps ports – and easily manage them all with a single IP address.

This stacking technology also provides several high-availability features to ensure business continuity:

• Resiliency: Due to redundant stacking port connections, there is an automatic fail-over in case any switch in the stack fails, with rapid reconfiguration, thus preventing network downtime.
• Hot-swappable: All switches in the stack are hot-swappable, and can be integrated or removed without disrupting the network.

Full-featured, Flexible Power over Ethernet (PoE)

With a total power budget of 192 Watts for the GS724TPS and 384 Watts for the GS748TPS, customers can choose to connect up to 48 802.3af IP-based devices in their network. Power-over-Ethernet (PoE) helps you optimize the installation and power management of network devices such as wireless access points (AP), Voice over IP (VoIP) phones, and IP-based surveillance cameras, and free your network deployment from restrictions of power outlet proximity using a standard Cat 5 cable. In addition, as the first in the industry, the first 4 ports on GS724TPS and GS748TPS also support PoE+, the IEEE 802.3at-based technology, providing up to 30 Watts of power for your high-powered PoE devices such as videophones, RFID readers, access control systems, etc. To facilitate power management, the switches are equipped with auto power budgeting functions, thus allowing the users flexibility in power management. Users can allocate the power by priorities, monitor power consumption and get alerts when power usage reaches a threshold.

Advanced Security

These switches also provide advanced features that provide more robust security to SMBs.

These include:

• 802.1x for authentication
• ACL filtering to permit or deny traffic based on MAC and/or IP addresses

Advanced Quality of Service (QoS)

Priority queuing ensures high-priority traffic gets delivered efficiently, even during congestion from high traffic bursts. Companies implementing network telephony or video conferencing, for example, need to be able to prioritize such voice and video traffic and other real-time applications over less latency-sensitive traffic to ensure reliability and quality. The ability to prioritize traffic ensures quality of latency-sensitive services and applications despite increasing traffic loads.

The ProSafe™ Gigabit Stackable Smart Switches provide an extensive set of QoS features:

• 802.1p-based prioritization
• Layer 3-based (DSCP) prioritization
• Rate-limiting

"Smart" Management Features

Manage all ProSafe™ Gigabit Stackable Smart Switches as though they were one unit from an easy-to-use Web console that can be used to configure all features, as well as monitor and troubleshoot. These switches also have SNMP (v1, 2 and 3) to collect and track data to monitor the network health, as well as manage devices, and more easily enforce critical IT controls and policies. SNMP v2c is most commonly deployed, as it provides better reporting capabilities than SNMP v1. Companies interested in more robust security may opt for SNMP v3, which provides data encryption.

All ProSafe™ Gigabit Stackable Smart Switches provide world-class reliability with a NETGEAR Lifetime Warranty and optional ProSupport Maintenance Packages. These switches are optimized for ProSafe™ Network Management Software (NMS100) and work with other SNMP-based management software.
