When you first insert the T1 card it must initialize and the NBX system
must update its database. You must wait 3 minutes because the T1 card

devices, you may need to allow additional time. If you attach a console
cable to the CONSOLE port on the T1 card and use Hyperterminal
software to view the text output from the card, you will see status
messages associated with the two reboot processes. See
“Connecting a
Computer to a Console Port” on page 196 .
