[Abstract]: What are the connection methods of PoE switches? When we introduced the monitoring power supply mode, we introduced a PoE power supply. Some friends have some questions nearly PoE ability supply. Today, the PoE switch manufacturer (ONV) volition employ the graphic form to learn nigh the four power supply modes and connections of PoE method.

What are the connection methods of PoE switches ? When we introduced the monitoring power supply fashion, nosotros introduced a PoE power supply. Some friends have some questions well-nigh PoE ability supply. Today, the PoE switch manufacturer ( ONV ) volition apply the graphic course to acquire about the four power supply modes and connections of PoE method.

First, PoE switches and terminals can back up PoE

The PoE switch is directly continued to the wireless AP and IP camera that supports PoE power supply through the network cable. Colleagues should pay attention to two points:

1 , Determine whether the PoE switch and the wireless AP or network camera are standard PoE devices.

2, T o carefully ostend the specifications of the purchased network cable, the quality of the network cable is critical, a poor quality network cablevision volition cause wireless AP or IP c amera cannot receive power or constantly restart.

Second, the PoE switc hes can support PoE and the terminal can't back up PoE.

The PoE switch is connected to the PoE splitter. The PoE splitter separates the ability supply into data signals and ability. In that location are two output lines, one is the power output line, and the other is the network information signal output line, that is, the ordinary network cable. The power output has 5V/9V/12V, etc. Information technology can match diverse DC input not-PoE powered terminals and supports IEEE 802.3af/802.3at standard. The data signal output line, that is, the ordinary network cable, tin be direct connected to the network port of the not-PoE ability receiving terminal.

3rd, the network switch es tin can't support PoE, and the concluding can support PoE.

The network switch comes out to connect to the PoE ability supply. The PoE power supply adds power to the network cable and transmits it to the terminal. This kind of scheme is conducive to expanding the original wiring network and has no impact on the original network.

Fourth , Ethernet switches and terminals cannot back up PoE.

The network switch comes out to the PoE power supply, and then to the PoE splitter, and finally to the last. The third and fourth schemes are suitable for the transformation of the traditional network, that is, the original network switch does not support the PoE power supply, but wants to take advantage of the PoE power supply.

In bodily application, how should the network cablevision exist continued? Many friends have some understanding of P o E power supply technology, knowing the power supply line order problems such every bit 1 / ii (+), 3 / six (-) or 4 / five (+), 7 / 8 (-) , so they are afraid of incorrect connection, resulting in serious consequences such every bit equipment called-for.

P o E power supply standard requirements for PSE equipment such as P o E switches and POE ability supply modules (POE power supplies) are as long as one of the i / 2 (+), three / 6 (-) or 4 / v (+), 7 / 8 (-) power supply lines is supported. Of course, the latest 802.3at 4 pair standard is required. Both are supported at the same fourth dimension. The requirement for POE powered devices is that they must back up both ability supply modes.

How to connect PoE switches?

1. If your POE switch and POE power supply module are standard PSE devices, and so the network cablevision will not exist burned if yous connect the wireless AP or IP photographic camera below. The standard POE powering process has a detection procedure that ensures that ability is not supplied to powered devices that are not standard.

two. If your PSE equipment is a strong supply type, you must carefully cheque the instructions before wiring. See if the power supply pivot is 1 / two (+), three / 6 (-) or 4 / 5 (+), vii / 8 (-) . If there is no manual, you lot tin can also utilise a chiliad ultimeter to discover if there is stability. The 12V/24V/48V output is the power supply pivot. The power supply pin is clarified, and the last device cannot exist straight continued. The wireless AP or IP camera at the other end should figure out what the input voltage is, and whether the network port circuit has been modified. If it has not been modified, the network port circuit may be burned after being connected. If the circuit is not modified, a POE separator is required.

Understand the above ii points, in the engineering application, before the wiring, the chest is full. In that location is a lot of non-standard devices on the market. If you demand it, you can choose the PoE devices and installation service on the ONV website.
