That's why we only buy the 12-port Power Dsine, the 24 port ones are over subscribed.
We are using Meru AP311's on ours. -Neil -- Neil Johnson Network Engineer The University of Iowa Phone: 319 384-0938 Fax: 319 335-2951 Mobile: 319 540-2081 E-Mail: neil-john...@uiowa.edu From: "Hanset, Philippe C" <phan...@utk.edu<mailto:phan...@utk.edu>> Reply-To: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU>> Date: Mon, 15 Aug 2011 19:31:06 +0000 To: <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU>> Subject: Re: [WIRELESS-LAN] 1200 Series AP's on a newer 2960s Cisco switch using POE Ken, (just throwing a flashing experience of our own...) Does it flash when you connect just one AP-1200 or if you connect many AP-1200? Switches or Midspan can only handle as much as the power supply can provide. So if you overload the system it will flash. We have had that problem when connecting more than 22 Aruba AP-125 to a PowerDsine 24 ports 6000 serie Midspan.

We use PowerDsine midspan power inserters for our AP power (they come in 6, 12, & 24-port versions so they are cheaper than buying power for a whole Cisco switch or blade when only a few ports need power; management is also easy via a Web interface). In order for them to power the old 1200 APs, we had to buy a special dongle from PowerDsine to make them work. You may have the same issue. Call or write offline if you have any questions about this. -jcw <image001.jpg> ------------------------------------- John Watters UA: OIT 205-348-3992 ________________________________ From:The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Taillon II, Kendall Sent: Monday, August 15, 2011 1:57 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: [WIRELESS-LAN] 1200 Series AP's on a newer 2960s Cisco switch using POE We are in the middle of adding new 2960s Cisco switches to are edge. When connecting our old 1200 series AP’s to the switch via POE, the switch interface just keeps flashing. Is this because the old AP’s use the old pre-standard POE? Our new 1142 series AP’s connect just fine. Is there any way to have the older AP’s use the newer POE through the switch port?
