Dual power supplies, redundant backup of key components; It supports the insertion of 3 service boards, which can flexibly expand the port density. It can be widely used in medium and large video surveillance networks, smart device networks, and campus core networks.

• Three service boards (TL-SH5250-LPU-R AND TL-SH5250F-LPU-R) are supported, and load balancing and mutual backup are supported
• Supports two power modules (TL-PSM400E-AC-R) and supports load balancing and redundant backup, reducing the risk of equipment downtime and service interruption
• 1 fan module is provided, which supports automatic speed adjustment and real-time speed display. The fan module has two built-in fans to dissipate heat from the entire machine and ensure that the chassis works within the normal temperature range
• Service boards, power modules, and fan modules all support hot-swap technology, and work with a series of fault detection and judgment mechanisms to greatly improve device reliability
• It supports TP-LINK commercial cloud platform management, and the operation and maintenance is simple and convenient
• The service board and power module (TL-PSM400E-AC-R) must be purchased separately

The 10 Gigabit service board is connected, and the system is highly scalable

TL-NS7503E-R has two types of service boards: TL-SH5250-LPU-R AND TL-SH5250F-LPU-R, which can be mixed TL-SH5250F-LPU-R
port specifications: 48SFP + 2SFP+, and TL-SH5250-LPU-R port specifications: 48GE + 2SFP+
TL-NS7503E-R can flexibly access 1~3 service boards according to actual needs, and provides up to 144 Gigabit ports in the whole frame to meet the requirements of high-density network access. All ports on the
service board support wire-speed forwarding, which can meet the requirements of high-speed networking in various scenarios.
*Service board TL-SH5250-LPU-R, The TL-SH5250F-LPU-R is sold separately

Redundant design of key components, greatly improving reliability

Supports 3 service boards to implement load balancing and mutual backup. Two power modules (TL-PSM400E-AC-R) are
provided to support load balancing and redundant backup, reducing the risk of equipment downtime and service interruption. The
fan module has two built-in fans to dissipate heat from the whole machine, and supports automatic speed adjustment to ensure that the chassis works within the normal temperature range
Service boards, main control boards, power modules, and fan modules all support hot-swap technology, and work with a series of fault detection and judgment mechanisms to greatly improve device reliability

It supports TP-LINK commercial cloud platform management, and the operation and maintenance is simple and convenient

It supports TP-LINK commercial cloud platform management, and the operation and maintenance is simple and convenient

Support login to TP-LINK commercial cloud platform through PC web and mobile APP, only need a TP-LINK ID, and easily realize remote management.

Real-time monitoring and display of the working status of each board, and the equipment running status is clear at a glance.

When network security, devices go offline, or configuration is abnormal, alarm information is automatically pushed, and faulty devices are highlighted in the topology, so that O&M personnel can quickly locate them.

Strong business processing capabilities

Supports inter-box stacking* to achieve link-level redundancy, expand the number of ports, improve reliability, and reduce O&M costs.
Supports BGP/OSPF/RIP dynamic routing protocols and static routing protocols to solve the routing and routing problems after complex networks are divided into subnets.
MAC address table depth up to 32K
DHCP servers are supported, which assign IP addresses
to hosts in the network DHCP relay is supported, and switches in different interfaces or subnets can also obtain IP addresses, reducing the number of DHCP servers
Support proxy ARP, so that hosts in different physical networks in the same network segment can communicate
normally IEEE 802.1Q VLAN, MAC VLAN, protocol VLAN, and private VLAN, users can flexibly divide VLANs
according to different needs GVRP is supported to implement dynamic distribution, registration, and attribute propagation of VLANs, reducing the amount of manual configuration and ensuring the correctness of
configuration. The VLAN VPN function encapsulates the outer VLAN tag for the user's private network packets at the public network access end, so that the packets carry the two-layer VLAN tag across the public network.
It supports QoS, three priority modes based on ports, 802.1P-based and DSCP-based, and Equ, SP, WRR, SP+WRR Four Queue Scheduling Algorithms
Support ACL, filter packets by configuring matching rules, processing operations, and time permissions, and provide flexible security access control policies
Support IGMP V1/V2 multicast protocol, MLD Snooping, IGMP Snooping, and meet the requirements
of multi-terminal HD video surveillance and video conferencing access IPv6 is supported, meeting the requirements of smooth IPv4 to IPv6 upgrade and IPv4/IPv6 hybrid networking

You can read the power consumption information of each board to understand the power consumption status of the whole machine

Complete security protection mechanism

Supports IP address, MAC address, VLAN, and port quaternary binding to filter data packets

ARP protection against ARP spoofing and ARP flood attacks
, which are common in LAN. IP source protection to prevent illegal address spoofing
, including MAC address spoofing, IP spoofing, and MAC/IP spoofing. DoS protection, Land Attack, Scan SYNFIN, Xmascan, Ping Flooding, and other attacks
It supports 802.1X authentication, provides authentication functions for LAN computers, and controls the authorization status of controlled ports according to the authentication results.
Supports port security, stops learning when the number of MAC addresses learned by the port reaches the maximum number, prevents MAC address attacks and controls port network traffic.
Support DHCP Snooping, effectively eliminate private DHCP servers, Ensure the legitimacy of the DHCP server
