Clearness, Electromagnetic Interference

L2 Managed Switch

Please keep a proper temperature and humidity in the equipment room. Too high/low humidity may lead to bad insulation, electricity leakage, mechanical property changes and corrosions. Too high temperature may accelerate aging of the insulation materials and can thus significantly shorten the service life of the device. For normal temperature and humidity of the device, please check the following table.

Environment	Temperature	Humidity

Operating	0℃ ~ 40℃	10% ~ 90%RH Non-condensing

Storage	-40℃~ 70℃	5% ~ 90%RH Non-condensing

Clearness

The dust accumulated on the Switch can be absorbed by static electricity and result in poor contact of metal contact points. Some measures have been taken for the device to prevent static electricity, but too strong static electricity can cause deadly damage to the electronic elements on the internal circuit board. To avoid the effect of static electricity on the operation of the Switch, please attach much importance to the following items:

■■ Dust the device regularly, and keep the indoor air clean.

■■ Keep the device well grounded and ensure static electricity has been transferred.

Electromagnetic Interference

Electronic elements including capacitance and inductance on the device can be affected by external interferences, such as conducted emission by capacitance coupling, inductance coupling, and impedance coupling. To decrease the interferences, please make sure to take the following measures:

■■ Use the power supply that can effectively filter interference from the power grid.

■■ Keep the device far from high-frequency, strong-current devices, such as radio transmitting station.

■■ Use electromagnetic shielding when necessary.

Lightening Protection

Extremely high voltage currents can be produced instantly when lightning occurs and the air in the electric discharge path can be instantly heated up to 20,000℃. As this instant current is strong enough to damage electronic devices, more effective lightning

TL-SG5428, TL-SG5412F specifications

The TP-Link TL-SG5428 and TL-SG5412F are advanced Ethernet switches designed to meet the demands of growing networks, offering robust performance, scalability, and a suite of features for simplified management. These devices are tailored for both medium-sized businesses and enterprise environments, ensuring reliable and efficient data transfer across connected devices.

The TL-SG5428, a 28-port Gigabit L2 Managed Switch, is equipped with 24 Gigabit Ethernet ports and 4 SFP (Small Form-Factor Pluggable) slots for fiber uplink. This versatility allows for high-speed connections to servers, storage devices, and other network components, enhancing overall network performance. In contrast, the TL-SG5412F features 12 Gigabit Ethernet ports, also complemented by 4 SFP slots, making it an ideal choice for smaller setups or branch offices.

One of the prominent features of both models is their support for advanced Layer 2 management, which includes VLAN (Virtual Local Area Network) support for improved network segmentation and security. This capability helps in organizing network traffic effectively and limits broadcast storms, ultimately enhancing network efficiency. Additionally, both switches support Link Aggregation Control Protocol (LACP), allowing multiple ports to be combined for increased bandwidth and redundancy.

Power over Ethernet (PoE) technology is another key aspect of these models. The TL-SG5428 and TL-SG5412F can deliver power to connected devices such as IP cameras, phones, and access points through the Ethernet cable, simplifying installation and reducing cable clutter. This feature is particularly beneficial in environments where power outlets may be limited or difficult to access.

Security features are also paramount in both switches. They come with 802.1X authentication to prevent unauthorized access and support for Access Control Lists (ACLs) to further protect sensitive data. Moreover, the switches have a robust web-based management interface and support SNMP (Simple Network Management Protocol), allowing for easy monitoring and configuration.

In terms of quality of service (QoS), both models can prioritize network traffic effectively using various algorithms, ensuring that critical applications receive the necessary bandwidth, which is crucial for maintaining the performance of voice, video, and data services.

In summary, the TP-Link TL-SG5428 and TL-SG5412F are versatile, feature-rich switches that provide essential tools for managing and optimizing network performance. With their combination of advanced security, PoE capabilities, and efficient traffic management, they are well suited for dynamic networking environments, ensuring reliable and scalable network solutions for businesses of all sizes.
