Lets put aside the term "standards-compliant" for a minute... (I'm not a parliamentarian by nature).
The fact of the matter is that 802.3af provides multiple ways to deliver power over an Ethernet cable. One is to do it via pins 4&5 and 7&8 (unused wire pairs), while the other is via 1&2 and 3&6 (overloaded with data). The 4826 uses the first option while a number of PoE switches (most?) use the second. Some PoE devices are designed to accept power via either set of pairs, but the 4826 is not one of them. There are a number of ways to work around this including using a different vendor for PoE injection, using external splitters, or by rewiring the 4826 board (John Bellardo, now at Cal Poly SLO, describes the latter approach at: http://sysnet.ucsd.edu/wireless/poe/) - Stefan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Richard StClair Sent: Tuesday, July 24, 2007 6:41 PM To: [email protected] Subject: Re: [Soekris] trouble with net4826 and powered USB hub > need the splitter because the net4826 isn't PoE standards-compliant, > and the splitter puts the power on a pair the net4826 can use.) Wait a minute.....on the 4826 specs page, Soekris says: "Supports Power over Ethernet according to the 802.3af standard" I haven't used 4826 with POE but we use our standard 48V POE with the 4511's and they work fine...and the Soekris site has the identical "Supports Power over Ethernet according to the 802.3af standard" line in the specs for the 4511. Is there something different about the 4826? -- Regards, Richard St Clair, -------------------------------------------- IT Policy: "Leave the geeks alone and everything will be fine". _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
