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.
