Daniel, The required power domain is 10W<> 130W. For 48V
operation this is beyond the 802 spec. The RJ-45 was/is listed as one of the
options to be considered. There is also pressure against that high a voltage. But this
has not been decided yet. Bob Davis UPAMD Chair. From: upamd@xxxxxxxx
[mailto:upamd@xxxxxxxx] On Behalf Of Leonard Tsai I don’t recall we discussed about 802.3at. Also, I am not sure if it is relevant but in future, many of the
mobile device will not have RJ45 due to ID design, size, power, etc.

[mailto:upamd@xxxxxxxx] On Behalf Of Feldman, Daniel Was there any discussion in to making the interface the same as in
IEEE802.3at-2009? The standard already has a universal connector (the RJ45)
which is present at the majority of portable computers, and allows the delivery
of 12.95W (Type 1 devices), 25.5W (Type 2 devices) or 51W (2xType 2 devices). It would save the cost of a connector and the standard already has
a provision for negotiating power and allocating power. From: upamd@xxxxxxxx [mailto:upamd@xxxxxxxx] On
Behalf Of Leonard Tsai As voltage drop by different length and grade of power cable,
this maybe not as ideal as digital communication. Just my opinion… Leonard From: upamd@xxxxxxxx
