Dahua DH-PFS4218-16ET-240-V3 - 16 Port Managed PoE Switch for CCTV

Dahua DH-PFS4218-16ET-240-V3 - 16 Port Managed PoE Switch

The Dahua DH-PFS4218-16ET-240-V3 is a layer 2 managed PoE switch, a network switch for PoE IP cameras and other PoE devices. It has 16 PoE ports at 100 Mbps and 2 Gigabit uplink combo ports (RJ-45 or SFP), with a total PoE budget of 240W. The two red ports, ports 1 and 2, support IEEE 802.3bt and Hi-PoE at up to 90W. Dahua lists it as the DH-PFS4218-16ET-240 (PFS4218-16ET-240 without the DH- prefix) and describes it as suited to small and micro-scale monitoring networks such as offices, schools, hotels, supermarkets and hospitals. Dahua's datasheet for the PFS4218-16ET-240 says its parameters apply to hardware version V2.0, and the specification below is taken from that datasheet; this listing is the V3, so check Dahua's documentation for the V3 for any detail you depend on.

Also listed as PFS4218-16ET-240-V3.

Key features

• 16 x RJ-45 10/100 Mbps PoE ports, plus 2 x combo uplink ports that take either a 10/100/1000 Mbps RJ-45 cable or a 1000 Mbps SFP module
• PoE standards IEEE 802.3af, 802.3at, Hi-PoE and 802.3bt; total PoE budget 240W, ports 1 and 2 up to 90W, ports 3 to 16 up to 30W
• Intelligent PoE: if the load goes over the budget the switch shuts down the highest numbered port first, rather than every port at once
• PoE watchdog: detects a port failure and restarts network communication on that port
• 250 m long distance PoE transmission (the speed drops to a maximum of 10 Mbps)
• Layer 2 management by web, CLI and SNMP-based software, with a console debugging port
• IEEE 802.1q VLAN, STP and RSTP, LACP link aggregation, port mirroring, IP and MAC binding, MAC filtering and 802.1x port authentication
• All-metal design, 4 kV common mode and 2 kV differential mode lightning protection, working from -10 °C to +55 °C

Technical specification

Works with

Dahua lists these SFP modules for the uplink ports: GSFP-1310T-20-SMF, GSFP-1310R-20-SMF (both 20 km single-mode) and GSFP-850-MMF (550 m multi-mode). Related switches: DH-CS4218-16ET-135 and DH-PFS4420-16GT-240. See all our PoE network switches.

Common questions

How many PoE devices can the DH-PFS4218-16ET-240-V3 power?

It has 16 PoE ports within a 240W total budget. Ports 1 and 2 can deliver up to 90W each and ports 3 to 16 up to 30W each, so the devices you connect must fit inside 240W in total. If the load goes over the budget, the highest numbered port is shut down first.

Are the PoE ports Gigabit?

No. The 16 PoE ports are 10/100 Mbps. The two combo uplink ports are 10/100/1000 Mbps RJ-45 or 1000 Mbps SFP.

Which ports give 90W PoE?

The red ports, ports 1 and 2, support IEEE 802.3bt and Hi-PoE at up to 90W.

How is it managed?

Dahua lists CLI, iLinksView, web and SNMP-based network management software, and the switch has a Console port.

Can it power a camera further than 100 m?

Dahua lists a long distance PoE function to 250 m. The speed drops to a maximum of 10 Mbps in that mode.

What does the PoE watchdog do?

It detects a network port failure and restarts network communication on the port, so it avoids a manual restart.

Is it a PoE switch for CCTV?

It is a managed layer 2 Ethernet switch with PoE on all 16 of its 10/100 Mbps ports. Dahua shows PoE IP cameras and an NVR in its application diagram, so it can be used as a CCTV PoE switch for small and micro-scale monitoring networks, as long as the connected devices fit inside the 240W PoE budget.
