FAQs about PoE Switch

Q: Non-PoE vs. PoE Switch: How do they differ?

A: Non-PoE switches cannot deliver power to connected devices, necessitating the use of midspan power sourcing equipment (PSE), such as a PoE injector. This setup adds power while transmitting data to powered devices (PDs). In contrast, PoE switches offer a simpler solution, directly delivering power and data to PDs with just a network cable and a power cable.

Q: Do PoE Switches Require Special Cables?

A: No. The Ethernet cables that should be used for PoE network switches primarily depend on the data rate of the PoE port; for instance, Cat3 or better cables can be used for 10/100M; Cat5/Cat5e/Cat6 cables are required for 1000M. In the future, Cat6a or higher cables may be required for the installation of 2.5G/5G/10G PoE devices.

 

Q: Active vs Passive PoE Switch: Should I Choose Active or Passive PoE Switches?

A: Active PoE network switch complies with standard PoE. On the contrary, passive PoE network switch does not adhere to any IEEE standard. There are many ways that active and passive PoE switches differ from one another, like how the PoE power supply pinout looks and whether or not they support Ethernet.

 Also Check- Active vs. Passive PoE Switch: Which Should We Choose?

 

Q: Can the PoE Switch be used with a computer or other non-PoE devices? And will a PoE switch harm devices that do not use PoE?

A: Yes, a PoE switch can be used with non-PoE devices like computers. The switch automatically detects whether a connected device is PoE-compatible and will only supply power to PoE-enabled devices. So, it won't harm non-PoE devices; they just won't receive power through the switch.

 

Q: Is it possible to connect two PoE switches?

A: You could, yes. The PSE only supplies PD with power when it determines that the device can handle it. As PSEs, the two PoE switches will only be used for data communications.

 

Q: What is the maximum transmission distance of PoE? How to extend the transmission distance of PoE?

A: Whether using IEEE 802.3af (PoE) or 802.3at (PoE+), data and power transmission are limited to a distance of 100 meters over Ethernet cables in standard PoE. Media converters and PoE extenders, for example, can extend the range to up to 300 meters if you want to increase the maximum distance.
