What is LM-4804FMGP-L2+ Extreme Switch?
An unmanaged switch like the LM-402UGP works as a straightforward network distributor. You connect your devices, power them on, and traffic flows automatically. There is no configuration panel, no login, and no risk of misconfiguration. From our experience working with CCTV vendors and system integrators, the LM-402UGP is often chosen for:
- Small camera clusters
- Branch offices
- Temporary installations
- Edge network extensions
It acts as a stable foundation rather than a control center, which is exactly what unmanaged switches are meant to be.
Key Features
High Port Density for Structured Networks
The LM-4804FMGP-L2+ extreme switch consists of 48 Gigabit PoE ports in a single switch. This allows you to connect a large number of devices without requiring additional hardware components. This cuts down the rack space in real deployments, eases cabling, and simplifies managing the network. It is a practical choice for office floors, retail outlets, and CCTV setups where many devices need to be connected at once. These are used in practice when the office floor, retail stores, and CCTV systems require a large number of machines to be linked simultaneously.
Reliable PoE Power for Continuous Operation
This switch supports 48 PoE/PoE+ ports with a total power budget of 450W. Each port can deliver up to 30W, which is sufficient to serve devices such as IP cameras, access points, and VoIP phones. Generally, when used in everyday life, stable PoE implies that devices do not require any additional power adapters, which minimizes the points of failure and makes the setup clean and reliable.
Fiber Uplink for Strong Backbone Connectivity
The 4 SFP uplink ports allow the switch to connect to the core network via a fiber cable. This assists in ensuring the continuity of communication over a longer distance and with a greater bandwidth. In multi-floor offices or large buildings, this ensures that data moves smoothly between network layers without losing any signals and degradation in performance.
Layer 2+ Control for Better Network Management
With L2+ features, the switch supports VLAN configuration, traffic control, and basic routing. This allows businesses to separate departments, manage traffic flow, and improve security within the same network. When two or more teams and systems are interconnected, it becomes easier to control the movement of data.
Stable Performance with Built-in Protection
The switch is designed to operate in hot environments where power issues can occur. It supports 6KV surge protection and works within a temperature range of -20°C to 55°C. Features like PoE watchdog (PD alive check) also help detect and restart unresponsive devices automatically, minimizing the amount of manual intervention and downtime.
Real Client Scenario Handled by Our Engineers
A 5-star hotel in Kenya approached our team after facing repeated network issues in their office and CCTV system. They had multiple IP cameras and access points, but the existing setup used separate power adapters and smaller switches. This created cable clutter, unstable connections, and frequent device downtime.
After reviewing the network from our team, we deployed the LM-4804FMGP-L2+ to handle both connectivity and power from a single switch. Once installed, all cameras and access points were powered directly through PoE, which removed the need for extra adapters. As a result, the network became stable, downtime was reduced, and the overall setup became cleaner and more efficient.

Frequently Asked Question (FAQ)
This is a type of switch that is used in areas where numerous devices are required to have simultaneous network access and get power through the same system. It is applicable in corporate offices, CCTV surveillance systems, retail stores, and high-rise buildings. Its ability to support PoE and provide high port capacity helps in simplifying the installations, but does not affect the performance.
The LM-4804FMGP-L2+ switch provides 48 PoE ports, which means up to 48 devices can be connected and powered directly. In the actual systems, companies have a combination of IP cameras, access points, and office systems connected. The extra SFP uplink ports can also be expanded by linking to other switches or the core network.
Yes, it supports IEEE 802.3af/at standards with a cumulative PoE capacity of 450W. This enables the use of more than one device simultaneously without power outages. Practically, this prevents such failures as camera stops or access points that reboot because of power instability.
Yes, this is one of its practical advantages. VLAN can be used to isolate office traffic and CCTV traffic on the same switch. This maintains the network in order and prevents the video information to impact office performance.
The 4 SFP ports are used for fiber uplinks to connect the switch to the core or aggregation layer. They help maintain stable, high-speed communication over longer ranges, which is useful in large buildings or campus settings.
The PoE watchdog tracks the linked devices and validates whether they have been turned on. In case a device becomes unresponsive, the port can be restarted by the switch. This saves manual troubleshooting and maintains running gadgets such as cameras.
Yes, it has 6KV surge protection to cope with voltage surges. This assists in securing the switch and other devices in places where the power is not so stable. It also minimizes the likelihood of hardware damage.
SPOLLEX provides complete support, including network design, installation, configuration, and training. We also offer AMC and continuous support contracts depending on your requirements. We have staff and knowledge of the locality and have made sure that your network is installed properly and can work without problems.
