Dahua DH-CHS4206-4ET-90 - 6-Port Cloud Managed Hardened Layer 2 Ethernet PoE Network Switch

Dahua DH-CHS4206-4ET-90 - 6-Port Cloud Managed Hardened PoE Network Switch

The Dahua DH-CHS4206-4ET-90 is a 6-port cloud managed hardened PoE network switch. Dahua names it the 6-Port Cloud Managed Hardened Switch with 4-Port PoE. It is a Layer 2 switch with four 10/100 Mbps PoE ports, two SFP 1000 Mbps uplinks and a 90 W total PoE budget, in a full metal, dust-proof enclosure for desktop or DIN rail mounting. A DIP switch turns managed mode on or off, and in managed mode the switch can be managed from its local web page or from the DoLynk Care cloud app.

Also listed as CHS4206-4ET-90.

Common questions

What type of switch is it?

It is a Layer 2 Ethernet switch: its four PoE ports are RJ-45 10/100 Mbps ports and its two uplinks are SFP 1000 Mbps ports.

How many PoE ports and what is the PoE budget?

Four RJ-45 10/100 Mbps PoE ports with a 90 W total budget: port 1 provides 90 W and ports 2-4 provide 30 W each, within the 90 W total.

Which PoE standards does it meet?

IEEE 802.3af, IEEE 802.3at, Hi-PoE and IEEE 802.3bt.

Can I manage it from my phone?

Yes. In managed mode it can be managed through the DoLynk Care app, which shows device status and sends alarm notifications, or through the local web page.

What are the uplink ports?

Two SFP 1000 Mbps ports (ports 5-6). Dahua lists optional SFP modules for them.

How far can a PoE port reach?

Dahua lists long distance PoE up to 250 m, with the bandwidth reduced to 10 Mbps (Extend mode, ports 1-4).

How is it mounted and what temperatures does it take?

Desktop or DIN rail mount, in an iron casing rated IP30 and IK06, operating from -30 °C to +65 °C.

What is in the box?

Dahua's datasheet lists a user manual, legal and regulatory information, a power cord, a power adapter and a terminal block.
