Kim, Out of curiosity, the 1602 is a Trapeze designed product? Is it based on the Trapeze 371? Single b/g radio?
I know, curiosity killed the cat. . . Just wondering, due to price, why you would choose the 1602 over a 422. Thanks Reese From: Kim Pedersen [mailto:[email protected]] Sent: Friday, March 20, 2009 6:29 AM To: Enterasys Customer Mailing List Subject: Re: [enterasys] AP 1602 Hi Jimmy, I think I can throw in a couple of cents worth here: The 1602 (And 4102s too AFAIK/Remember) need the antenna to provide DC Short or else the external antenna port won't activate and remains "stuck" using the internal antenna regardless of which antenna you set the AP to use in the software settings. The Enterasys/Trapeze branded antennas all provide the DC Short, so they work. Most other 3rd party antennas don't. Many amplifiers will provide the DC Short, so if you insert on of those between the omni and the AP, it will work correctly. This bit us in the behind when we were installing a distributed antenna system using 70 1602s for the WiFi signal. As a cheaper and simpler alternative to using amplifiiers, we found a lightning arrestor at L-Com that provides the DC short. (http://www.l-com.com/productfamily.aspx?id=6194) Our installation had 70 access points, and we ended up getting a 140 of these arrestors. Yes, they are only rated for operation between 2.3-2.7GHz, but they do the trick for the 5GHz antenna port as well (With an increase in VSWR) Hope it helps, and saves you some of the many hours we spent on the problem. P.S. We opened a product improvement case with Enterasys, but after a year they determined this couldn't be done. I think it must be a limitation in the Trapeze design of the hardware, as well as HiPath is the future now Kind regards, Kim Pedersen CNCS Ltd.

There is a setting in RASM that allows you to configure the type of antenna that you are connecting the AP to. Either internal or external. The antennas that I have tried, never switch over when you make that change and deploy it. I think at one time I heard someone say something about the antenna required to have a dc coupler. However, I am not sure I know what that means and how to determine if an antenna has that or not.

When you say they don't work, do you mean very poor performance? I noticed all antennas that are supported by 1602 are 50 ohms, could it be possible that the antennas you tried were not 50 ohms? No matter what though, even if you used a paperclip, you should get some kind of signal, otherwise I'd suspect maybe it's a config/defect issue. Thank you, Adrian G.

This is the AP that looks like a smoke alarm. I have found a couple that will not work but none yet that will.

I think we used a 19dBi for max output power. Unless I'm mistaken, any antenna will work so as long as you use the correct wavelength. Thank you, Adrian G.

Enterasys documentation does not show support for an omni attached to an AP-1602 however, I can't imagine that there isn't one that will work. Hope someone knows. Thanks for the help.
