Thanks George, I actually do want to boot the operating system on the SD 
card which has two partitions made according to instructions at 
http://eewiki.net/display/linuxonarm/BeagleBone+Black. The operating system 
I installed on the SD card is ubuntu-13.04-console-armhf-2013-07-22.tar.xz. 
The LEDs are operating as I expect from booting my other image (which also 
boots the SD card) but was a downloaded image as opposed to a compiled 
image. When I apply power, the LEDs light up after a few seconds as 
expected. When I hold the reset switch down, then after about 8-10 seconds, 
the LEDs turn off, again as expected when an SD running machine is turned 
off. Everything looks right except for the closed ports.
