Power Over Ethernet Switch

POE or Power over Ethernet (IEEE 802.3 AF Standard) is a special feature found in many networking devices including digital VOIP phones, cameras, security systems, switches, and many other devices.  This feature allows Ethernet cables to supply the power for various networking devices, while transmitting and receiving data in the normal way.   Typical PoE customers are businesses wanting to grow their network or adding additional digital VOIP phones in offices and buildings where new power lines would be expensive and/or inconvenient.

Here are the basics you need to know about PoE 802.11 AF Standard:

  • Device supplying the Power is known as Power Sourcing Device (PSE)
  • Device receiving the Power is Known as Powered Device (PD)
  • Normal Power Sourcing Devices provide 15.4 watts of power.
  • 15.4 watts of power can be divided between several PDs.
  • Both PSE and PD can either send or receive power, but not both.

 Things You Should Consider before Buying PSE or PD’s:

Start by looking at how many PoE powered devices you need to add to your network.  Each powered device will have specific power requirements.   You need to carefully calculate how much total power you will need for all powered devices.

For example, Cisco SPA 504G VoIP Phone requires 1.79 Watt. If you were to add 24 Cisco SPA 504G phones to your network, you will need total of 42.96 watts of power.    You should shop for PSE based on this number.    You may notice that 802.11 AF standards only calls for 15.4 watts of power but you can find many devices that can easily exceed this requirement.

For example, In this case you may consider Cisco SF300-24P PoE Switch.  This switch can provide up to 180 watts of power, more than enough to power all 24 phones.   Some other PD products such as wireless access points and security cameras take significantly higher power.  Therefore, switch like Cisco SF300-24P is an ideal PoE solution for small businesses.

 Benefits of using Power Over Ethernet or PoE :

  •  Ease of installation for both PSE and PD.
  • Allows flexibly for adding or moving devices to new location.
  • Cost and Time savings of installing new electrical outlets.
  • One less power adapter to manage for each PD device.
  • PSE optimizes power use to reduce energy costs and protect environment.
  • Automatic power shutoff on PSD ports when link is down.
  • Most Cisco PSE utilizes chipsets that allow for lower power consumptions.
  • Better power management using SNMP and UPS.

Now that you know the power of PoE, make sure to consider power over ethernet devices next time you are thinking about adding any device to your network.
