Passive Power over Ethernet Switch PSW-508D

Are you using access points or outdoor WiFi units that use a non-standard PoE power supply?
Would you like to power these products from a switch but they won’t work with standard 48V PoE switches?

Well the answer is the PSW-508D passive PoE switch from Solwise!

The PSW-508D is an 8 Gigabit port PoE switch which allows you to fix the PoE voltage simply by changing the power supply used with the switch.  This means if you use a 12V power supply then the PoE voltage is 12V. Use a 15V power supply and it’s 15V. Use a 24V power supply and it’ll supply 24V PoE. It’s that easy!

Maximum current on each port is 1Amp (this is the specified limit for current allowed on an RJ45 LAN connector) so, for example, use a 4A 24V power supply and all 7 PoE ports will be able to supply 12W and 24V or you could have 4 ports giving one Amp at 24V.

Simple WiFi Link – link buildings using Wireless


In this video we learn how to create a simple WiFi link. In this scenario we link up two buildings on a farm to enable farm workers to use their handheld devices in the farm office.

Managed WiFi Networks

With the increasing importance of wireless networks in the corporate, educational and hospitality world and the proliferation of WiFi infrastructure to service these demands, it has become even more important that the network administrator has the tools at hand to quickly manage, configure and generally administer the various elements of the network. At its most basic this might be simply to change the SSID of one particular access point (AP) or, at the other end of the scale, it might be to en-mass administer a firmware update; the ability to centrally control and manage all elements of the WiFi network is now a vital tool for any system where there is a large, distributed wireless infrastructure.

The basic elements of any managed wireless system is a collection of distributed access points (APs) which connect through wired network connections to the access controller (AC). The access controller is the device or server which facilitates control functions of the APs. The AC unit can take the form of a stand alone controller, a WLAN switch, or even a computer/software implementation. Although a wired network would be the norm for control connectivity to the access points, it is also possible to use a secondary wireless infrastructure for the data connectivity.

Fat, Thin, and Fit APs

In a managed WiFi network, consisting of multiple access points and the access controller, the level of data control and management the AC has to furnish depends upon the level of autonomous operation the APs have. Continue reading…

WiFi at the Lawns Caravan Show 2014

The Hull and East Riding of Yorkshire Caravan Manufacturers’ Association runs The Lawns Caravan Show every September, to introduce the new season’s caravans.  The Lawns Show in Cottingham, near Hull, generally features more than 130 new touring caravans and about 150 caravan holiday-homes, lodges and park homes from most of the major British manufacturers. Following the Extravaganza there is a trade only event. The show attracts about 3,500 visitors from throughout the UK, and many parts of Europe and Scandinavia – and sometimes even further afield.
