EXTRALINK - Ideal PoE switches for IP monitoring

 

Ideal PoE switches for IP monitoring


extralink poe logo

 


Nowadays, there are more and more devices in LAN network. Significant amount of such devices can generate many technical problems connected with the necessity of structured wiring expansion or creation of new power points. Repeatedly this is quite problematic and that is why there are some standards which help to solve this problem.


What PoE stands for?


 

 

Power over Ethernet (802.3 af/at) is a power supply system for devices with the aid of the most commonly used network cable – Cat 5e twisted pair or higher. PoE supply can be used for 10, 100, and 1000 Mbps, yet providing power to devices has no effect on the data transmission.

Thanks to this solution, by using a single network cable you can transmit both data and electricity. In short, PoE enables to simplify the process of entire installation and also the need of connecting devices to 230V.

Whereas such a change has its impact on increasing power consumption by power supply device.

It should also be noted that the PoE standard was defined in 2003 providing 15,4W power for each connection. In fact, the device gets 12,95W while the rest is earmarked for losses due to the transmission of electricity.

 

PoE standards

 


 

 

At this moment, there're three applied standards to transmit power by the network cable:

- PoE (802.3af)

- PoE+ (802.3at)

- UPoE


The oldest PoE is able to deliver 15,4W, PoE+ to 30W while UPoE (Universal PoE) up to 60W.

 

The following graphic shows the development of PoE standard:


poe history

 

PoE+ has been introduced due to higher power consumption for powered devices. Analogously the same reason led to the introduction of UPoE – standard introduced by Cisco which can energize equipment even to 60W.

UPoE uses 4 pairs of cables to transmit power. Thus, such a solution provides power supply for e.g. virtual desktop displays, various access controllers and LED lights.

PoE standards are clearly illustrated by the table below:

where:

PSE – power sourcing equipment – a power supply device

PD – powered device – a device powered via PoE

 

 

PoE switch for IP cameras


 


Ok, now let's get to the point...

PoE switch is one of the most important elements of IP monitoring networks because it connects all network devices to each other e.g. IP cameras, recorders or VoIP telephones. It also provides PoE power supply for all network devices which support this standard.

It should also guarantee the consistent work of the entire system in situation of high intensity of data streams.

Extralink has released a new product on the market – 8-port, unmanaged, gigabit PoE switch with 2 uplink ports (1xRJ45 1000M and 1xSFP 1000M) named KRONOS.

Extralink KRONOS is characterized by the following features:


poe specification


Thanks to the fact that KRONOS has two uplink ports – one supports SFP and SFP 1000M and the other RJ-45 1000M – it’s an ideal solution for network structure based on IP monitoring.

Attached diagram shows that EXTRALINK KRONOS easily supports a large number of cameras, VoIP phones and devices that support wireless network (Mimosa B5) in 802.3at (48V) standard.

In addition, by using e.g. Ubiquiti INSTANT 802.3af you can also easily power such devices that need 24V.

Its universality and the maximum load of 260W allows the implementation of such a switch practically anywhere in the office network or/and even in industrial one.
