Dahua DH-LR2110-8ET-120-V2 - 10-Port Unmanaged Ethernet Network Switch

Dahua DH-LR2110-8ET-120-V2 - 10-Port Unmanaged Network Switch

The Dahua DH-LR2110-8ET-120-V2 (LR2110-8ET-120-V2 without the DH- prefix) is a 10-port unmanaged network switch and PoE switch with 8 ePoE ports. Dahua ePoE technology carries PoE and data over Ethernet cable up to 800m at 10Mbps, or up to 300m at 100Mbps, so IP CCTV cameras can be sited a long way from the switch. As a CCTV PoE switch it powers and connects IP cameras over long Ethernet cable runs. It is a layer 2 switch and an unmanaged Ethernet switch, with a Gigabit RJ-45 uplink and an SFP uplink, and it works as soon as it is powered on, with no configuration. Dahua states that the datasheet parameters apply to V2.0 of this model.

Also listed as LR2110-8ET-120-V2.

Key features

• Long distance PoE: ePoE up to 800m at 10Mbps, or up to 300m at 100Mbps.
• 120W total PoE power across 8 PoE ports: ports 1 and 5 up to 90W each, ports 2, 3, 4, 6, 7 and 8 up to 30W each.
• Dahua says the red ports support IEEE802.3af, IEEE802.3at, IEEE802.3bt and Hi-PoE standards, up to 90W per port, for high power devices.
• Layer 2 unmanaged switch: plug and play, no configuration needed.
• Eight-pin PoE: pins 1, 2, 4, 5 positive and 3, 6, 7, 8 negative, so signal lines and idle lines supply power at the same time. Dahua says this improves compatibility with IP cameras and reduces cable loss.
• Intelligent PoE: power consumption control and real-time monitoring give priority to important ports and help prevent malfunctions caused by changes in power consumption.
• Wide operating temperature of -30 °C to +65 °C, with built-in lightning-proof circuits.
• Port indicator light shows the transmission mode of each port: IEEE, E100 or E10.
• Suited to small-scale scenes such as offices, schools, hotels, supermarkets and hospitals.

Common questions

How far can the DH-LR2110-8ET-120-V2 carry PoE?

With ePoE, Dahua gives up to 800m at 10Mbps, or up to 300m at 100Mbps. Its transmission table for Cat6 cable lists 100Mbps from 100m to 300m and 10Mbps at 400m, 500m and 800m, with the PoE power available falling as the cable gets longer. Send us your cable length and camera model and we will help you check it.

How much PoE power does it supply?

120W in total. Ports 1 and 5 supply up to 90W each and ports 2, 3, 4, 6, 7 and 8 up to 30W each. Dahua lists IEEE802.3af, IEEE802.3at, IEEE802.3bt and Hi-PoE support.

Is it a managed switch?

No. Dahua lists the management type as No. It is a layer 2 unmanaged switch that works as soon as it is powered on.

What uplink ports does it have?

Port 9 is an RJ-45 10/100/1000 Mbps port and port 10 is an SFP 1000 Mbps port. The SFP modules above are listed in Dahua's ordering information.

How can I mount it?

Dahua lists rack mount and DIN guide rail mount, so it can be installed in a rack or used as a DIN rail switch.

What temperature range does it work in?

-30 °C to +65 °C, with relative humidity of 10% to 90%, non-condensing.

Does it come with a power adapter?

Dahua lists an included power adapter, with an external power supply of 54 VDC, 2.22 A.
