SKU: LK7052XGSM Category:

LK7052XGSM is a Managed PoE+ Switch, which is equipped with 48 10/100/1000BASE-T ports, 4 1Gb SFP/10Gb SFP+ uplinks, 48 RJ45 ports support both IEEE 802.3af PoE and IEEE 802.3at PoE+ (up to 30W per port) for powering attached IP phones, wireless access points, or other standards-compliant PoE and PoE+ end network devices. 4 SFP+ uplink ports are provided to support connections to higher layer aggregation or core switches.

Rich PoE Management Function
Being the managed PoE switches for CCTV surveillance, wireless and VoIP networks, LK7052XGSM 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
LK7052XGSM can be configured to monitor connected PD status in real time. Once the PD stops working and responding, the PoE switch 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
LK7052XGSM allows 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, LK7052XGSMcan 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, LK7052XGSM enables 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.

10Gbps Uplink Capacity for Big Bandwidth Application
10G Ethernet is a big leap in the evolution of Ethernet. The 10G SFP+ slots support dual-speed 10GBASE-SR/LR or 1000BASE-SX/LX, meaning the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. It is a cost-effective solution for SMB network to achieve the maximum performance of the 10G networks

Solution for IPv6 Networking
With the IPv6/IPv4 dual stack and other management functions, the LK7000 series 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
LK7052XGSM 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. The LK7000 series allows the operation of a high-speed trunk combining multiple ports.

Powerful Security Functions
LK7052XGSM 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
LK7052XGSM 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, LK7052XGSM is a managed PoE switch,which is equipped with console, web and SNMP management interfaces. With management interface, LK7052XGSM offers an easy-to-use, platform independent management and configuration facility. LK7052XGSM supports SNMP and it can be managed via any management software based on the standard SNMP v1 or v2 Protocol. Meanwhile LK7052XGSM offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these switches. Moreover, LK7052XGSM 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
LK7052XGSM supports 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.
