What is LM-4804FMGP-L2+?
The LM-4804FMGP-L2+ is a high-density PoE switch designed to connect and power multiple network devices from a single system. It delivers both data and power through Ethernet ports while providing Layer 2+ management features for traffic control, security, and monitoring. In practical deployments, it is used as an access or distribution switch where many PoE devices need stable connectivity and centralized management.
Key Features
High-Density PoE for Large Deployments
The LANMUS LM-4804FMGP-L2+ Managed switch has 48 PoE-enabled ports and a total power budget of 450W. This switch can support a large number of devices such as IP cameras, access points, and VoIP phones. It eliminates the necessity to use separate power sources and simplifies the process of installation in offices, campuses, and surveillance systems.
Fiber Uplink for Stable Backbone Connectivity
The 4 SFP uplink ports deliver a stable fiber connection to the aggregation or core switches. This makes sure that as many devices are operating, information can flow inside the network without any congestion between layers of the network.
Advanced Layer 2+ Network Control
The switch supports VLAN segmentation, static routing, ACL policies, and QoS management, which allow IT teams to control traffic flow, separate networks, and prioritize critical applications for better performance.
Quick Network Recovery with Redundancy Protocols
This switch also supports STP, RSTP, MSTP, and ERPS. The switch can quickly recover from link failures. This guarantees minimal downtimes and stable communications, particularly in those environments where network availability is a factor.
Strong Security for Controlled Access
Inbuilt capabilities like 802.1X authentication, IP-MAC binding, and ACL filtering can be used to secure the network. These controls prevent unauthorized access and protect sensitive data across connected devices.
Easy Management and Monitoring
The switch is controllable using Web interface, CLI, SNMP, and SSH. It also supports system logs, traffic monitoring, and diagnostics tools, thus making it easier to maintain and troubleshoot the network by the IT teams.
Durable and Fanless Design
The switch has a metal enclosure, no fan cooling, and a broad operating temperature range, which was designed to operate in various environments with stable operation. It can be used in indoor and semi-industrial settings without requiring regular maintenance.
Real Client Scenario Handled by Our Engineers
In Kenya, a logistics firm installed a large CCTV surveillance system in several warehouses. The problem was managing both the power and connectivity of dozens of cameras while keeping the network running well.
Our team implemented the LANMUS LM-4804FMGP-L2+ as the main access switch. It used PoE to power all cameras and uplink them to the core network using fiber uplinks. The system became more manageable, downtime was minimized, and video surveillance was consistent even when the system was at its peak operations once deployed. The client could also add the system without altering the current infrastructure.
When is it best to use LANMUS LM-4804FMGP-L2+?
The LANMUS LM-4804FMGP-L2+ is a good choice when your network has a large number of PoE devices that need both power and connectivity from a single switch. It can be used in surveillance systems, enterprise networks, and infrastructure configurations where centralized control is considered significant. It is also well-suited when you require stable fiber uplinks to enable connectivity to core switches and maintain control over traffic, security, and performance across a variety of connected devices.

Frequently Asked Question (FAQ)
The primary use of this switch is in networks where several PoE devices should be connected and managed centrally. It is commonly used in surveillance systems, office networks, warehouses, and infrastructure projects. Since it supports both power and data to be carried over a single cable, thus simplifying the installation in a place where it is not feasible to run separate power lines.
The switch has 48 PoE ports, which means that the switch is able to directly connect up to 48 powered devices like cameras, access points, or IP phones. Moreover, the 4 SFP uplink ports enable it to be connected to the next higher level switches, making it applicable when expanding networks to additional devices.
Yes, it does support PoE based on IEEE 802.3af/at standards. It implies that each port can provide two types of services: network connectivity and power to compatible devices. It simplifies the process of installation and is particularly applicable to the devices that are located in areas with a shortage of power outlets.
The switch offers a switching capacity of 104 Gbps and provides support for wire-speed forwarding. This means that in cases where there are a lot of devices operating, data processing is efficient and there are no delays. Such features as QoS are also used to give priority to important traffic to achieve better performance.
Yes, the 4 SFP ports can be used to provide fiber uplink connections to the aggregation or core switches. This renders it applicable to long-distance connectivity and high-speed backbone communication in a network of enterprises or campuses.
The switch has several security measures that include ACL filtering, port isolation, 802.1X authentication, and IP-MAC binding. These features help control access, prevent unauthorized devices from connecting, and protect the network from internal and external threats.
Yes, it is designed for stable performance with features like redundancy protocols (STP/RSTP/MSTP/ERPS), surge protection, and a fanless, durable build. These characteristics mean that this switch can be used continuously with minimal chances of going dead.
SPOLLEX provides full support, such as consultation and deployment, configuration, and AMC contracts. Our team will make sure that the switch is well integrated with your network and that it remains reliably operational over time with continued support and maintenance.
