What we love about Planet Products is the high performance and

For higher power PoE network applications with Gigabit speed transmission, PLANET introduces the SGSW-24040HP. This 24-Port Gigabit High Power over Ethernet Managed Switch features high performance Gigabit IEEE 802.3af PoE (Up to 15.4W) and IEEE 802.3at High-Power PoE (Up to 30.8W) on all ports.

By supporting reliable stacking technology and advanced networking features, SGSW-24040HP also provides high scalability for current and future network infrastructure as it can flexibly work with PLANET SGSW series Gigabit Switches.

A maximum of 30.8 Watts is available on the Gigabit ports of the SGSW-24040HP for powered devices, with a maximum PoE delivery of 360 Watts for all ports. Providing Gigabit throughput and high power the SGSW-24040HP optimizes the installation and power management of devices like 11n wireless access points (AP), network video cameras, large screen PoE Video phones, thin-clients, etc.

The SGSW-24040HP provides a built-in SMTP and SNMP Trap alarm function that can send instant alarm to the administrators by email when errors happen (like when the connected PD devices change, or when the Ethernet cable is disconnected. The switch also records when the error happens and the recovery status.

The PoE schedule function helps you to enable or disable PoE power feeding for each PoE port during specified time intervals to help conserve power and save money.

The SGSW-24040HP supports both IPv4 and IPv6 management functions.

The SGSW-24040HP provides 2 dedicated High-Speed HDMI-like interfaces for stacking. With up to 16 units of stacking, 384 Gigabit PoE ports can be managed.

The SGSW-24040HP 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-24040HP provides 802.1Q Tagged VLAN, with up to 255 VLAN groups allowed.

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

The SGSW-24040HP 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 of 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. The SGSW-24040HP 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.

The two mini-GBIC slots built in the SGSW-24040HP support Dual-Speed, 100Base-FX and 1000Base-SX/LX SFP (Small Form-factor Pluggable) fiber-optic modules, that means, 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.

High power and high speed data switching are integrated into one unit and delivered over a single cable, the Gigabit PoE Switch also lowers the need for dedicated electrical outlets on the wall, ceiling or any unreachable place and eliminating costs and time for additional AC wiring.
