PFS3211-8GT-120-V2 8-ports Switch

PFS3211-8GT-120-V2 is a gigabit PoE switch from Dahua, which is designed for IP monitoring systems. This industrial switch has 8 RJ45 1Gbps ports with PoE 802.3af/at (power over ethernet) capability, 1 RJ45 1Gbps Uplink port and 2 SFP ports. It complies with IEEE 802.3af, IEEE 802.3at and IEEE802.3bt 90W standards (first 2 ports), and the total PoE power budget is 120W. In addition, the network switch has PoE 2.0 technology, including functions such as PoE watchdog, intelligent PoE and support for 250m long distance mode. The front panel consists of LEDs that indicate the operating status of the device. In addition, the switch has been designed to suit both a free-standing setting and a larger installation such as a DIN rail housing.

PFS3211-8GT-120 is an intelligent PoE switch with an 8-pin PoE power supply with the possibility of assigning Poe over a long distance. It is equipped with Watchdog Poe, BT 90W and All-Giga ports, which makes it an ideal choice for demanding and reliable Poe applications. This switch also has a wide operating temperature range, thanks to which it is suitable for various environments. Thanks to advanced functions, PFS3211-8GT-120 is the perfect choice for your PoE applications.

Dahua switch in PoE 2.0 technology

---

Dahua Poe 2.0 switches are professional transmission devices specially designed to work in IP monitoring systems. Currently, the entire series of pounds Dahua Switches has been fully updated and contains practical functions such as: BT 90W power supply - red port (selected models) and PoE transmission over long distances.

Watchdog PoE

---

Switch Dahua offers a 24 -hour control of the condition of devices connected to PoE ports. In the absence of communication (e.g. suspension of the device), the switch will automatically detect a failure and re -supply the tested device reset.

The highest level of performance

---

The unhealthy Dahua network switch operates based on automated recognition, adaptation and management of active connections, as well as maintaining the highest level of work efficiency at the lowest demand for electricity. In addition, the installation and use of the device is very simple, thanks to the Plug Nad Play technique. The advantage of Switch Dahua is also the universal shape of the housing that allows the switch to operate the freedom as a free -standing device and as part of a larger installation located in the Rack ICT wardrobe.

Support for SFP modules

---

The DAHUA network switch allows you to cooperate with various types of optical fiber, thanks to the built -in SFP modules. All optical transmission parameters are conditioned from the selected SFP module. The Poe Dahua switch works with SFP modules compatible with the IEEE 802.3Z 1000Base-X standard.

The new IEEE 802.3bt PoE standard

---

The new IEEE 802.3BT allows you to provide much more power to devices (max. 90W). Provides power transmission via all four twisted pairs of wires and supports the transmission speed of up to 10GB/s for network devices connected via the CAT5E cable. The new POEEE 802.3BT standard contains a number of new functions and improvements compared to the older version of 802.3at. Devices with relatively high power requirements, such as flat -screen displays, high -power wireless access and even desktop computers can now operate in PoE systems.

Redundant power

---

Redundanty power supply is a method of supplying the switch, which is associated with double supply supply to the device. This method is used in the event of a failure of one of the power sources. It enables automatic switch to an equivalent source directly through the switch without the user's participation.
