RE: VERY OT: POE over SFP module

Thanks... that was already discussed. E-series is a different hardware platform, not an IOS code upgrade.

It's on cisco.com.

Check the -E documentation and/or Enchanced POE.

Tony,

I just checked 12.2(50)SE and later release notes for 2960/3560/3750 and it
only shows 15.4 Watts/port max.

http://www.cisco.com/en/US/partner/docs/switches/lan/catalyst3750/software/r
elease/12.2_50_se/release/notes/OL18263.html#wp784383

If you have other documentation, I'd like to see it, the power bricks for
the 1250's suck.

You should look at the later versions of Cat IOS code. They can provide
higher wattages for the 1250s.

(just saw Ryan's email ... but I wrote this a few minutes earlier ... good
update Ryan)

Hey Pavel and team,

Just to add in a little bit more here ...

1140n uses standard POE ... wireless N, without the need for enhanced. This
is a nice AP with multiple radios etc ...
http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps10092/datasheet
_c78-502793.html

The 1250 series power will depend on the number of radios you have
installed. W/ one radio, N radio, you may be fine with standard POE as it
will come just under the 15 watts limit ... this will not allow you to have
a G radio at the same time though ... and there would be no interop between
the two.

Still suggested to use ePOE. A power injector is a cheap method if only
doing one AP or so ... too many more than 1 AP makes the power injectors an
operational cost / headache. Best to go with the ePOE as Pavel mentions ...
