Centralized Power Management for Gigabit Ethernet PoE Networking
To fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the WGSW-20160HP features high performance Gigabit IEEE 802.3af PoE (Up to 15.4 watts) and IEEE 802.3at PoE+ (Up to 30 watts) on all ports. It perfectly satisfies the PoE IP camera which needs high power consumption such as IR, PTZ, speed dome cameras or even box type IP cameras with built-in fan and heater.

The PoE capabilities provided also help to reduce deployment costs for network devices as a result of freeing from restrictions of power outlet locations. Power and data switching are integrated into one unit, delivered over a single cable and managed centrally. It thus eliminates cost for additional AC wiring and reduces installation time.

Built-in Unique PoE Functions for Surveillance Management
As a managed PoE Switch for surveillance network, the WGSW-20160HP features four special PoE Management functions:
■　PD ALIVE Check
■　Scheduled Power Recycling
■　SMTP/SNMP Trap Event Alert
■　PoE Schedule

Intelligent Powered Device Alive Check
The WGSW-20160HP can be configured to monitor connected PD (Powered Device) status in real-time via ping action. Once the PD stops working and is without response, the WGSW-20160HP 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 reduce administrator management burden.

SMTP/SNMP Trap Event Alert
Though most NVR or camera management software offers SMTP email alert function, the WGSW-20160HP further provides event alert function to help to diagnose the abnormal device owing to whether or not there is a break of the network connection, loss of PoE power or the rebooting response by PD Alice Check process.

PoE Schedule for Energy Saving
Besides being used as an IP Surveillance, the WGSW-20160HP is certainly applicable to construct any PoE network including VoIP and Wireless LAN. Under the trend of energy saving worldwide and contributing to the environmental protection on the earth, the WGSW-20160HP can effectively control the power supply besides its capability of giving high watts power. The “PoE schedule” function helps you to enable or disable PoE power feeding for each PoE port during specified time intervals and it is a powerful function to help SMB or Enterprise save power and money.

Efficient Management
For efficient management, the WGSW-20160HP Managed Switch is equipped with console, WEB and SNMP management interfaces. With the built-in Web-based management interface, the WGSW-20160HP offers an easy-to-use, platform-independent management and configuration facility. The WGSW-20160HP supports standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based management software. For text-based management, the WGSW-20160HP can be accessed via Telnet and the console port. Moreover, the WGSW-20160HP offers secure remote management by supporting SSH, SSL and SNMPv3 connection which encrypt the packet content at each session.

Robust Layer 2 Features
The WGSW-20160HP 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 / MLD Snooping. The WGSW-20160HP provides 802.1Q Tagged VLAN, and the VLAN groups allowed will be maximally up to 255. Via aggregation of supporting ports, the WGSW-20160HP allows the operation of a high-speed trunk combining multiple ports and supports fail-over as well.

Powerful Security
The WGSW-20160HP 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, communication between edge ports can be prevented to ensure user privacy. The WGSW-20160HP also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discarding ARP packets with invalid MAC address. The network administrators can now construct highly secured corporate networks with considerably less time and effort than before.
