LK7026GCM is a managed L2 Gigabit switch PoE+ (802.3af/at) switch with 24 10/100/1000M BAST-T ports and 2 100/1000M BASE-X SFP slots. 24 gigabit Ethernet ports supports IEEE802.3.af/at, up to 30W PoE output per port. It supports soft-based IPv4/IPv6 static routing and other management function, which makes it an ideal solution for small business and enterprise projects.

Rich PoE Management Function
Being the managed PoE switches for CCTV surveillance, wireless and VoIP networks, LK7026GCM features the following special PoE management functions:
■ PoE PD-alive check
■ Scheduled power rebooting
■ PoE schedule
■ PoE usage monitoring
■ Soft-reboot PoE Non-stop
■ PoE port power feeding priority

Smart PoE PD-Alive Check
LK7026GCM can be configured to monitor connected PD status in real time. Once the PD stops working and responding, LK7026GCM will resume the PoE port power and bring the PD back to work. They will greatly enhance the network reliability through the PoE port resetting the PD’s power source and reducing administrator management burden.

Scheduled Power Rebooting
LK7026GCM allow each of the connected PoE IP cameras or PoE wireless access points to reboot at a specified time each week. Therefore, they will reduce the chance of IP camera or AP crash resulting from buffer overflow.

PoE Schedule for Energy Saving
For energy saving and environmental protection purpose, LK7026GCM can effectively control the power supply besides their capability of giving high watts power. The PoE schedule function helps to enable or disable PoE power feeding for each PoE port during specified time intervals and it is a powerful function to help SMBs or enterprises save power and money.

PoE Usage Monitoring
Via web interface, LK7026GCM enable the administrator to monitor the status of the power usage of each connected PD in real time. Thus, they greatly enhance the management efficiency of the facilities.

Solution for IPv6 Networking
With the IPv6/IPv4 dual stack and other management functions, LK7026GCM is the best choice for IP CCTV surveillance, VoIP and wireless solution providers to develop the IPv6 network. Meanwhile they help the SMBs to upgrade their network infrastructures to the IPv6 era without any extra investment.

Robust Layer 2 Features
LK7026GCM can be programmed for advanced switch management functions, such as port aggregation, Q-in-Q VLAN, Spanning Tree Protocol, QoS, bandwidth control, ERPS IGMP/MLD snooping etc. LK7026GCM allows the operation of a high-speed trunk combining multiple ports.

Powerful Security Functions
LK7026GCM provides a comprehensive access control list (ACL) for enforcing security to the edge. It can be used to restrict to network access by denying packets based on source and destination IP address, TCP/UDP port number 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.

Enhanced Security and Traffic Control
LK7026GCM supports 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 administrator can now construct highly-secure corporate networks with considerably less time and effort than before.

User-friendly Secure Management
For efficient management, LK7026GCM is equipped with console, web and SNMP management interfaces. With management interface,LK7026GCM offers an easy-to-use, platform independent management and configuration facility. The LK7026GCM supports SNMP and it can be managed via any management software based on the standard SNMP v1 or v2 Protocol. Meanwhile the LK7000 series offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these switches. Moreover,LK7026GCM offers the remotely secure management by supporting SSH, SSL and SNMP v3 connection where the packet content can be encrypted at each session.

Intelligent SFP DDM Function
LK7026GCM support SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
