Description

Full-Functioned Layer 2 / Layer 4 Managed Switch for Enterprise and Campus Networking
The PLANET SGSW-2840R is a 24-Port 10/100Mbps Fast Ethernet Switch with 4-Port Gigabit TP/ SFP Combo interfaces, which boasts high performance switch architecture. The SGSW-2840R is capable of providing non-blocking switch fabric and wire-speed throughput as high as 12.8 Gbps, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands. Its four built-in Gigabit Ethernet uplink ports also offer incredible extensibility, flexibility and connectivity to the core switch or servers.

AC / DC Power Redundant to ensure continuous operation
The SGSW-2840R is equipped with one 100~240V AC power supply unit and one additional DC -48V power supply unit for redundant power supply installation. A redundant power system is also provided to enhance the reliability with either 100~240V AC power supply unit or DC -48V power supply unit. The continuous power systems are specifically designed to handle the demands of high tech facilities requiring the highest power integrity. Furthermore, with the -48V DC power supply implemented, the SGSW-2840R can be applied as the telecom level device that could be located at the electronic room.

Robust Layer 2 Features
The SGSW-2840R can be programmed for basic switch management functions such as port speed configuration, Port aggregation, VLAN, Spanning Tree protocol, QoS, bandwidth control and IGMP Snooping. It provides IEEE 802.1Q Tagged VLAN and the VLAN groups allowed on the SGSW-2840R will be maximally up to 256. Via aggregation of supporting port, the SGSW-2840R allows the operation of high-speed trunk combining multiple ports. Maximum up to 8 ports can be assigned for 12 trunk groups and it supports fail-over as well.

Excellent Traffic Control
PLANET SGSW-2840R is loaded with powerful traffic management and QoS features to enhance services offered by telecoms. The QoS features includes wire-speed Layer 4 traffic classifiers and bandwidth limiting applications that are particular useful for multi-tenant unit, multi business unit, Telco, or Network Service Providers. It also empowers the enterprises to take full advantages of the limited network resources and guarantees the best performance in VoIP and Video conferencing transmission.

Efficient IP Stacking Management
The SGSW-2840R supports IP Stacking function that helps network managers to easily configure up to 36 switches in the same series via one single IP address instead of connecting and setting each unit one by one. For efficient management, the SGSW-2840R is equipped with console, WEB and SNMP management interfaces. With its built-in Web-based management, the SGSW-2840R offers an easy-to-use, platform-independent management and configuration facility. It supports standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based management software. For text-based management, the SGSW-2840R can be accessed via Telnet and the console port. Moreover, the SGSW-2840R offers secure remote management by supporting SSL and SSH connection which encrypt the packet content at each session.

Powerful Security
The PLANET SGSW-2840R offers comprehensive Access Control List (ACL) for enforcing security to the edge. Its protection mechanism also comprises port-based IEEE 802.1x user, Web Authentication user and device authentication. The port-security is effective in limiting the numbers of clients pass through so that 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 embedded in the SGSW-2840R are compatible with 1000Base-SX/LX and WDM SFP (Small Form Factor Pluggable) fiber-optic modules. The distance can be extended from 550 meters (Multi-Mode fiber cable) or up to 10/30/50/70/120 kilometers (Single-Mode fiber or WDM fiber cable). They are well suited for applications within the enterprises data centers and distributions.
