Per your schematic, the diode is installed correctly. However, we usually
look at the cathode end as pin 1 (square pad) so this is a conflict. Since
on many of our boards, space is limited and sometimes the triangular symbol
can not be used, we stress to install pin 1 (marked end, cathode) in the
square hole to make it easier for the operator.

Mornin' All!
There's been a pretty interesting thread going on in the Designers Council
about what is supposed to called pin 1 of a diode...the Anode or the
Cathode. Believe it or not, there's been conflicting answers. So I'd like
to do a little test.
Look at:

and tell me if we installed this LED correctly.
Then look at:

and tell me if this this illustration guide I made for our operators is
correct.
(This ought to be good)
