D.2 Normal Terminal Server Operations
The terminal server automatically runs self tests when you apply power to the unit or use the
RESET button to initialize the unit. Upon successful completion of the self tests, the terminal
server loads software from a memory card, or over the network from a load server.
During the self test and software loading, the lights (LEDs) on the front panel flash to
reflect various types of activity. During self-test, you should observe the following light
activity:
