Got yourself a free Aerohive 121 AP after a recent training course or webinar? Got it home and found it's got no PSU!? Yeah, annoying isn't it... Get yourself one of these 'bad boys' off Amazon - bought one this week and works a treat! http://www.amazon.co.uk/dp/B004V2IZG4/ref=pe_217191_31005151_3p_dp_1 Disclaimer : if it blows your AP up don't blame me...mine certainly worked OK :) *** Update 11th October 2013*** Works well for an AirTight C-55 AP too!

Sometimes you can walk on to a customer site and the customer may have iPad devices using the WiFi network. They may also have a range of different models, so that it is difficult to perhaps know the WiFi support capabilities available among their devices.

If you are using a Cisco 2500 Series Controller and you upgrade to the 7.4.100.0 controller software release and intend to use the Application Visibility and Control (AVC) and NetFlow protocol features, you must install Cisco Unified Wireless Network Field Upgrade Software, Release 1.8.0.0. This release is not required if you are using other controller hardware models." http://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_1_8_0_0.html This definitely worth noting if you are upgrading to 7.4, as the new AVC features will not work without it. Also, it is well worth attaching a console cable whilst doing the upgrade as it takes a long time (around 30 minutes). Without the console, you'll be sitting there with your fingers crossed, breaking out
