Steve,
Looks like your LED is installed correctly (but better check the
schematic!)  

The illustration on the other hand may be incorrect.  According to IPC's
Desk Reference Manual DRM-18 (Component Identification), page 17
indicates that the square land would be the cathode.

Subject: [TN] Diode Pin Numbering Question...

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)
