Dahua DH-CHS4212-8GT-110 - 12-Port Cloud Managed Hardened Gigabit Ethernet PoE Network Switch

Dahua DH-CHS4212-8GT-110 - 12-Port Cloud Managed Hardened Gigabit PoE Network Switch

The Dahua DH-CHS4212-8GT-110 is a 12-port cloud managed hardened Gigabit PoE network switch. Dahua names it the 12-Port Cloud Managed Hardened Gigabit Switch with 8-Port PoE. It is a Layer 2 switch with eight 10/100/1000 Mbps PoE ports, four Gigabit uplinks (two SFP and two RJ-45) and a 110 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 cloud.

Also listed as CHS4212-8GT-110.

Key features

• Long distance PoE up to 250 m (bandwidth reduced to 10 Mbps) and a PoE watchdog that restarts failed PoE ports
• Full metal, dust-proof enclosure, -30 °C to +65 °C operating temperature, IP30 and IK06

Technical specification

Works with

The two SFP uplink ports take SFP modules. Dahua lists these optional modules for this switch:

• Dahua GSFP-850-MMF - Gigabit SFP module, LC, 550 m, multi-mode (optional accessory listed in the datasheet)
• Dahua GSFP-1310R-20-SMF - Gigabit SFP module, LC, 20 km, single-mode (optional accessory listed in the datasheet)
• Dahua GSFP-1310T-20-SMF - Gigabit SFP module, LC, 20 km, single-mode (optional accessory listed in the datasheet)

Common questions

What type of switch is it?

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

How many PoE ports and what is the PoE budget?

Eight RJ-45 10/100/1000 Mbps PoE ports with a 110 W total budget: ports 1-2 provide up to 90 W each and ports 3-8 provide 30 W each, within the 110 W total.

Which PoE standards does it meet?

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

What are the uplink ports?

Four uplinks: ports 9-10 are SFP 100/1000 Mbps and ports 11-12 are RJ-45 10/100/1000 Mbps. Dahua lists optional SFP modules for the SFP ports.

Can it be managed remotely?

Yes. In managed mode it can be managed through the local web page or the cloud platform, with network topology management over LLDP.

What protects against loops?

Loop protection raises a loop alarm and starts an elimination mechanism, and the switch also supports Spanning Tree Protocol and link aggregation.

How is it mounted and what temperatures does it take?

DIN rail or desktop 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.
