NetGear GS748TS ProSafe 48-Port Stackable Switch

NetGear GS748TS ProSafe 48-Port Stackable Switch

Growing companies rely on their network to provide the foundation for essential business applications: mission-critical data applications, security, Voice over IP (VoIP), video-conferencing and much more. Businesses that are growing rapidly want full-featured network switches that can accommodate growth, support the full range of network applications and secure the network without the overhead and complexity of fully-managed switches. The ProSafe Gigabit Stackable Smart Switch family delivers the scalability, flexibility, reliability, and performance growing small and medium-sized businesses need in an affordable and easy-to-manage package.

A first in the industry, each ProSafe Gigabit Stackable Smart Switch comes with 24 or 48 10/100/1000 Mbps ports with four shared SFP ports that provide high performance Fibre connections for bandwidth-intensive applications like ERP and large file transfers. In addition, two dedicated ports on the rear of the switch provide a 20 Gbps, dual-ring, highly redundant stacking bus that accommodates growth and offers the highest level of resiliency, thus 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. Finally, these switches come with a complete suite of advanced features for more robust security, higher quality of service and high availability. This switch is equipped with highly advanced features such as access control lists (ACL), 802.1x port authentication, enhanced QoS, rate limiting and IGMP snooping among others to provide a small and mediumsized business with a network that is geared for growth while providing scalability and reliability.

An intuitive, Web-browser interface provides simple yet comprehensive management, making it a snap to fully realize the potential of the rich feature-set offered by these switches. Why buy fullymanaged stackable network switches designed and priced for the enterprise? NETGEAR ProSafe Gigabit Stackable Smart Switches are designed for small and medium-sized growing businesses.

Each ProSafe Gigabit Stackable Smart Switch comes with 2 dedicated high-speed stacking ports on the rear of the switch providing 20 Gbps of bandwidth. Stack as many as six switches as you grow, and yet maintain high-speed connectivity across the stack with stacking cables. 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.

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 addresses or IP addresses.

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
• TCP/UDP-based prioritization

Manage all ProSafe Gigabit Stackable Smart Switches as though they are one unit from an easy-to-use Web console that can be used to configure all features, as well as monitor and trouble-shoot. 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.
