8 Port PoE (Yönetilmeyen) ile 11-Port Gigabit Switch

Name: 8 Port PoE (Yönetilmeyen) ile 11-Port Gigabit Switch
Brand: Dahua
SKU: PFS3211-8GT-120

Stock Code: PFS3211-8GT-120

Carries eight gigabit PoE ports to the backbone over two fiber uplinks and one copper uplink.

Running every port at gigabit speed, this unmanaged PoE switch rounds out eight PoE ports with two SFP uplinks and one RJ-45 uplink. Port 1 and port 2 feed up to 90 W through IEEE 802.3bt. It supports wall mounting and an anti-theft lock hole.

Key features

Port layoutPort 1-8: 8 × RJ-45 10/100/1000 Mbps PoE; port 9-10: 2 × SFP 1000 Mbps uplink; port 11: 1 × RJ-45 10/100/1000 Mbps uplink.

PoE budgetAllocates 90 W to ports 1-2 and 30 W to ports 3-8, never passing 120 W in total.

PoE standardsSupports the IEEE 802.3af, IEEE 802.3at, Hi-PoE and IEEE 802.3bt protocols and carries power over 8 pins.

Long distanceReaches 250 m of PoE transmission and carries intelligent PoE, PoE power management and PoE watchdog.

SwitchingForwards 16.37 Mpps at 33 Gbps capacity and holds a 1.75 Mbit buffer.

Field conditionsWorks from -30 °C to +65 °C at 5% to 95% relative humidity, drawing 5 W when idle and 120 W at full load.

Long-distance PoE figures apply under a 53 V supply with CAT5E/CAT6 cable of at most 10 Ω/100 m DC resistance; actual distance varies with the power draw of the connected device and the cable condition.
