Centralized Power Management for Enterprise and SMB Power over Gigabit Ethernet Networking
To go for more popular Gigabit PoE network applications, PLANET SGSW-24040P/SGSW-24040P4 is the 24-port Gigabit PoE Managed Stackable Switch. Besides supporting the reliable stacking technology and advanced networking features, the SGSW-24040P/SGSW-24040P4 features high performance Gigabit Power over Ethernet (PoE), which optimizes the installation and power management of network devices such as wireless access points (APs), Voice over IP (VoIP) phones, and security video cameras. The SGSW-24040P series also provides high scalability for current and future network infrastructures as they can flexibly work with PLANET SGSW series Gigabit Switch to meet the various networking requirements and simplify the network deployment and management.

The SGSW-24040P series Gigabit PoE Switch is ideally applicable for large scale of network deployment in enterprises, telecoms or campuses. A high performance with cost-effective solution is achieved by the SGSW-24040P series PoE Switch providing Gigabit throughput and power supply to PoE compliant devices including 802.11n AP with Gigabit PoE LAN port, mega-pixel PoE IP camera, PoE VoIP phones and more. Power and high speed data switching are integrated into one unit and delivered over a single cable, eliminating costs and time for additional AC wiring. The Gigabit PoE Switch also eliminates the need for dedicated electrical outlets on the wall, ceiling or any unreachable place. A maximum of 15.4W is available on the Gigabit ports for powering PDs (Powered Devices), with a maximum per device PoE delivery of 380W available for all ports to satisfy the increasing needs for power consumption of powered devices.

Cost-effective IPv6 Managed Gigabit Switch Solution for SMBs
The SGSW-24040P series can work with the original network structure (IPv4) and also support the new network structure (IPv6) in the future. With easy and friendly management interfaces and plenty of management functions included, the SGSW-24040P series is the best choice for ISP to build the IPv6 FTTx edge service and for SMB to connect with the IPv6 network.

High-Density, Resilient Deployment Switch Solution for Growing Gigabit Networking
The SGSW-24040P/SGSW-24040P4 provides 24 10/100/1000Mbps Gigabit Ethernet ports with IEEE 802.3af PoE injector, 4 shared Gigabit SFP slots, and 2 dedicated High-Speed HDMI-like interfaces for stacking with the series of switches. By applying the SGSW-24040 series, up to 16 units, 384 Gigabit Ethernet ports can be managed by a stacking group and you can add ports and functionality as needed. The 2 built-in stacking ports providing 5Gbps bandwidth and up to 20Gbps Bi-directional speed, it can handle an extremely large amount of data in a secure topology linking for backbone or high capacity network server with 68Gbps switching fabric per unit. The stacking technology also enables the chassis-based switches to be integrated into SGSW-24040 series Managed Switch at an inexpensive cost.

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.

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 four 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.
