The stacking technology also enables the chassis-based switches to be integrated into SGSW-24040 series Managed Switch at an inexpensive cost.

Cost-effective IPv6 Managed Gigabit Switch Solution for SMBs

The SGSW-24040 series supports both IPv4 and IPv6 management functions. They can work with original IPv4 network structure and further support the new IPv6 network structure in the future. With easy and friendly management interfaces and plenty of management functions included, the SGSW-24040 series is the best choice for ISP to build the IPv6 FTTx edge service and for SMB to connect with the IPv6 network.

Highlt Reliable Stacking Management

The SGSW-24040 series applies the advantage of the stacking technology to managing the stack group with one single IP address, which helps network managers to easily manage a stack of switches instead of connecting and setting each unit one by one. Through its high bandwidth tunnel and stacking technology, the SGSW-24040 series gives the enterprises, service providers and telecoms flexible control over port density, uplinks and switch stack performance. The stack redundancy of the SGSW-24040 series ensures that data integrity is retained even if one switch in the stack fails. You can even hot-swap switches without disrupting the network, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands.

Robust Layer 2 Features

The SGSW-24040 series can be programmed for advanced switch management functions such as dynamic Port link aggregation, Q-in-Q VLAN, private VLAN, Multiple Spanning Tree protocol (MSTP), Layer 2 to Layer 4 QoS, bandwidth control and IGMP Snooping. The SGSW-24040 series provides 802.1Q Tagged VLAN, and the VLAN groups allowed will be maximally up to 255. Via aggregation of supporting ports, the SGSW-24040 series allows the operation of a high-speed trunk to combine with multiple ports. It enables a maximum of up to 12 groups of 16 ports for port link aggregation, and supports fail-over as well.

Easy and Friendly Traffic Control

PLANET SGSW-24040 series is loaded with powerful but easy traffic management and QoS features to enhance services offered by telecoms. The functionality includes QoS features such as wire-speed Layer 4 traffic classifiers and bandwidth limit that are particular useful for multi-tenant unit, multi business unit, Telco, or Network Service Provide applications, such as VoIP, video streaming and multicast applications. The embedded handy QoS configuration wizard helps you set up a typical network application rules easily and quickly via Web interface. The SGSW-24040 series also empowers the enterprises or campuses to take full advantages of the limited network resources and guarantees the best performance in Voice and Video conferencing transmission.

Efficient and Secure Management

For efficient management, the SGSW-24040 series Managed Ethernet Switch is equipped with console, WEB and SNMP management interfaces. With the built-in Web-based management interface, the SGSW-24040 series offers an easy-to-use, platform-independent management and configuration facility. The SGSW-24040 series supports standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based management software. For text-based management, the SGSW-24040 series can be accessed via Telnet and the console port. Moreover, the SGSW-24040 series offers secure remote management by supporting SSH, SSL and SNMPv3 connection which encrypt the packet content at each session.

Enhanced Security

The SGSW-24040 series offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications. Its protection mechanism also comprises 802.1x Port-based and MAC-based user and device authentication. With the private VLAN function, communications between edge ports can be protected to ensure user privacy. New SGSW-24040 series net Security also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrators can now construct highly secured corporate networks with considerably less time and effort than before.

Flexibility and Extension Solution

The two mini-GBIC slots built in the SGSW-24040 series support dual speed, 100Base-FX and 1000Base-SX/LX SFP (Small Form-factor Pluggable) fiber-optic modules, meaning the administrator now can flexibly choose the suitable SFP transceiver according to the transmission distance or the transmission speed required. The distance can be extended from 550 meters (Multi-Mode fiber) up to above 10/50/70/120 kilometers (Single-Mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.

AC / DC Power Redundant to Ensure Continuous Operation ( SGSW-24040R )

Particularly for the SGSW-24040R, it is equipped with one 100~240V AC power supply unit and one DC -48V power supply unit to provide an enhanced reliable and scalable redundant power supply installation. The continuous power system is specifically designed to fulfill the demands of high tech facilities requiring the highest power integrity. The -48V DC power supply implemented makes the SGSW-24040R the telecom level device that can be located in the electronic room.

For small area network communication such as on the campus and community, the PLANET SGSW-20404 series Managed Stackable switches enable an affordable and scalable network deployment. Multiple SGSW-24040 series switches may be connected together to constitute a chain or ring stack topology using the 5Gbps stacking ports as interconnect links. Up to 16 units, 384 high-density Gigabit Ethernet ports can be managed by a stacking group with a single IP address. Furthermore, up to 64 mini-GBIC/SFP ports are available for remote uplink connectivity in a stacking group and provide the uplink to the edge network through Gigabit Ethernet LX/SX SFP modules. The SGSW-24040 series stackable switching system gives you the flexibility to expand small area network when needed.

Gigabit Ethernet supported equipment has become the fundamental unit of enterprises and network servers. The SGSW-24040 series stackable Gigabit switch can easily provide cost-effectiveness, high-density and high-bandwidth. Dedicated stacking features built into the SGSW-24040 series switch makes all devices in the stack operate together as a one much larger switch providing multiple high performance Gigabit Ethernet network for backbone of enterprise or telecoms. The SGSW-24040 series switch is ideal to be used as a server farm switch connecting servers. With the dynamic link aggregation function, a 16 GB fat pipe is provided for connecting to the backbone if required.

The dual power supplies provide the SGSW-24040R the non-stop network service ability. Besides the AC power input, the DC power supply can be chosen as -48V DC power input source or redundant power for the SGSW-24040R. The SGSW-24040R can take electrical power either from the AC outlet, the DC outlet or both for redundancy.
