All of your questions Tom are important and have taken those into consideration.
Right now, I just want to figure out if anybody has done it and how. We have made a POE system that puts out 48volt and it works on the bench with VL units, but when there is a significant cable run it stops working, I guess the important thing to find out is what is the minimum and maximum voltage that can be sent to a Alvarion VL or B radio? -Cameron -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Randy Cosby Sent: Thursday, October 09, 2008 1:07 PM To: WISPA General List Subject: Re: [WISPA] Alvarion VL Rackmount I have got to put a plug in for the "SuperRMS". We just installed our second unit. Just a great box for doing DC power control (or AC if you want). Pricey, but very flexibile and powerful. Also has temperature, voltage measurent, alarm contact monitoring, USB port with camera drivers, alert and relay scripting, linux shell and on and on.... http://www.remotemonitoringsystems.ca/rms2/ Tom DeReggi wrote: > There are three questions that come up... > > 1) Redundancy > 2) minimizing impact of failure > 3) Ability to remote reboot. > > We had chosen to stay with individual AC Adapter POE systems, for the above > reasons. > The individual AC PS adapter plugged into the AC style Digital Logger reboot > device. > If a PS fails, only one radio dies, and quick to replace the one PS for $15. > And if a radio locks up, we can reboot the port via Digital logger. > Whether or not our device is located in the Closet, mid-way on tower, or way > up the tower, its one standard method to remote access the devices, and > power them. > > So to run one cetnral power supply to power all radios....
