Confirming Proper Bootup Operation
Given proper headend support and DSAN hardware setup, the DSAN will be
configured automatically during the bootup period that immediately follows power-
up.

Important: The DSAN bootup process takes several minutes to complete. There is no
video output from the unit until the bootup process is complete.

To confirm proper bootup operation, choose the appropriate set of steps below. The
verification sequence varies depending on whether the DSAN already has a valid
configuration file loaded.

Bootup Sequence (Valid Configuration Stored)
Complete the following steps to monitor the bootup sequence that occurs when a
valid configuration is stored in the DSAN cache.
1 Before applying power to the DSAN, open the unit and connect a PC laptop to
valid configuration is stored in the DSAN cache.
1 Before applying power to the DSAN, open the unit and connect a PC laptop to
the diagnostic port as described in CLI Diagnostics (on page 73).
2 Apply power. After about one minute, the console prints DSAN Initializing…
and displays a progress bar.
3 After about two more minutes (three minutes from power-up), a dsan login:
prompt appears on the PC laptop screen.

Log in to the DSAN using the default user ID dsan and password dsan1234. Both
user ID and password are case-sensitive. The DSAN> prompt appears.

5 At the DSAN> prompt, type diag and then press Enter to display page 1 of the
DSAN diagnostic screens. Verify that the POST (Power On Self Test) passed.
The DSAN now performs two operations simultaneously. The first is to output
video using the cached configuration. The second is to begin the cable modem
registration process. In the next two steps, you will first confirm the video
output, and then observe the cable registration process.

Confirm that the front end successfully completes its configuration. Remap
State changes to Remap Send as it configures the video decoders, and at
completion, changes again to Channel Remapped.
