Switch DAHUA DH-LR2110-8ET-120 L2 8x Fast Ethernet (10/100) PoE, 48–57V, 8,8 Gbit/s, MAC 8000, preto

Dahua DH-LR2110-8ET-120 is an L2 network switch with eight Fast Ethernet (10/100) RJ-45 ports and integrated Power over Ethernet (PoE) support. It provides a switching capacity of 8.8 Gbit/s and a MAC address table for up to 8,000 entries. The device complies with IEEE 802.3/802.3u/802.3ab/802.3x/802.3af/802.3at standards and operates from a 48–57 V DC power source. Dahua ePoE technology enables extended PoE transmission distances to simplify surveillance system design and reduce cabling costs while maintaining compatibility with common IP cameras and basic office network equipment.

Advantages

The switch supports extended PoE transmission: up to 800 meters at 10 Mbps and up to 300 meters at 100 Mbps using Dahua ePoE technology, enabling long-distance connections without additional power supplies. It is compatible with IEEE 802.3af and 802.3at PoE standards and also supports PoC/Hi-PoE, providing flexible power options for cameras and other PoE devices. The device’s L2 feature set with MAC auto learning and aging and an 8K MAC table helps maintain efficient packet forwarding in small LANs. Its compact black housing and industrial temperature design make it suitable for installations in constrained or varied environmental conditions.

Suitable for

• PoE-based IP camera deployments and surveillance systems
• Small office and branch LANs requiring PoE endpoints
• Long-distance PoE links where in-line power or remote power injectors are impractical
• Basic network edge switching for sensors, access points, or VoIP phones

How to use

Install the DH-LR2110-8ET-120 on a shelf or in a small rack with adequate ventilation and connect the 48–57 V DC power supply. Connect IP cameras or other PoE devices to the RJ-45 ports using standard Ethernet cables; the switch will provide power and data to compatible PoE devices automatically. For longer runs, select appropriate cable quality and consider the ePoE distance limits: up to 800 m at 10 Mbps or up to 300 m at 100 Mbps. Configure basic L2 settings on upstream switches or management systems as needed; the MAC auto learning and aging operate without manual MAC address configuration.

Recommendations

Use shielded or high-quality UTP cabling for extended runs and verify cable condition to maintain link stability at longer distances. When planning deployments with multiple PoE devices, calculate total PoE power budget and confirm that the connected devices do not exceed the switch’s available PoE power. Place the switch in a location that meets its operating temperature range and provides proper airflow to ensure reliable performance.
