Intelligent Long Reach PoE Switch on Coaxial-based Network
PLANET LRP-422CST, a brand-new Multi-channel Long Reach PoE Switch, features an extended Ethernet and PoE networking of up to 1 kilometer over the existing coaxial cables going to multiple PoE compliant devices. It provides IPv6/IPv4 dual stack management and built-in L2/L4 Gigabit Switching engine along with 4 BNC ports with Long Reach PoE Injector function, 2 Gigabit copper ports and 2 extra 100/1000BASE-X SFP fiber slots. Each of the BNC ports provides 36 watts of power with a total power budget of up to 150 watts. As an advanced PoE switch, the LRP-422CST features intelligent PoE functions to improve the availability of critical applications. It provides a quick, safe and cost-effective PoE network solution to upgrading the existing coaxial cable infrastructure from the analog system to the HD IP surveillance system.

Multi-channel Long Reach Power over Ethernet
To support the enterprises in easily building a multi-channel and centrally-controlled Long Reach PoE system, the LRP-422CST works with the Long Reach PoE Extenders, LRP-101CE, via its 4 BNC ports being the Long Reach PoE injectors for all connected LRP Extenders. Each of the BNC ports features long range data and power transmission for distance up to 1,000m (3,280ft) over coaxial cable to the LRP Extender, and another 100m over Ethernet cable to remote PoE IP camera, PoE wireless AP or access control systems complied with 802.3af/at PoE.

Daisy-chaining Multiple Nodes
PLANET Long Reach PoE solution can easily build a power system for centrally-controlled IP cameras in a high availability network infrastructure. It gives users the flexibility to expand small area network with BNC T-connector for sharing four nodes per port when needed, making the LRP-422CST with 4 BNC Long Reach PoE Ports an ideal support for up to 16 PoE powered devices.

Intelligent Powered Device Alive Check
The LRP-422CST can be configured to monitor connected PD (Powered Device) status in real time via ping action. Once the PD stops working and responding, the LRP-422CST will resume the PoE port power and bring the PD back to work. It will greatly enhance the network reliability through the PoE port resetting the PD’s power source and reducing administrator management burden.

IPv6/IPv4 Dual Stack
Supporting both IPv6 and IPv4 protocols, the LRP-422CST helps the SMBs to step in the IPv6 era with the lowest investment as its network facilities need not be replaced or overhauled if the IPv6 FTTx edge network is set up.

Robust Layer 2 Features
The LRP-422CST can be programmed for advanced switch management functions such as dynamic port link aggregation, 802.1Q VLAN and Q-in-Q VLAN, Multiple Spanning Tree Protocol (MSTP), Loop and BPDU Guard, IGMP Snooping, and MLD Snooping. Via the link aggregation, the LRP-422CST allows the operation of a high-speed trunk to combine with multiple ports such as an 8Gbps fat pipe, and supports fail-over as well. Also, the Link Layer Discovery Protocol (LLDP) is the Layer 2 Protocol included to help discover basic information about neighboring devices on the local broadcast domain.

Powerful Security
PLANET LRP-422CST offers comprehensive IPv4/IPv6 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 user and device authentication, which can be deployed with RADIUS to ensure the port level security and block illegal users. With the Protected Port function, communication between edge ports can be prevented to guarantee user privacy. Furthermore, Port Security function allows to limit the number of network devices on a given port.

Advanced Network Security
The LRP-422CST 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 build highly-secure corporate networks with considerably less time and effort than before.

Friendly and Secure Management
For efficient management, the LRP-422CST is equipped with console, Web, Telnet and SNMP management interfaces. With the built-in Web-based management interface, the LRP-422CST offers an easy-to-use, platform-independent management and configuration facility. By supporting the standard Simple Network Management Protocol (SNMP), the switch can be managed via any standard management software. For text-based management, the switch can be accessed via Telnet and the console port. Moreover, the LRP-422CST offers secure remote management by supporting SSH, SSL and SNMP v3 connections which encrypt the packet content at each session.

Intelligent SFP Diagnosis Mechanism
The LRP-422CST also supports SFP-DDM (Digital Diagnostic Monitor) function that can easily monitor real-time parameters of the SFP for network administrator, such as optical output power, optical input power, temperature, laser bias current and transceiver supply voltage, thus increasing the efficiency of network management.
