Troubleshooting Adapter Cards, Cables, and Connections
Network problems can be caused by an adapter card, cables or cable connections, or external devices
such as a hub, wall jack, WAN interface, or terminal. Check for the following symptoms to help isolate
the problem:
• Adapter card is not recognized by the Cisco ADE 2130 and 2140 Series appliance.
–
Make sure that the adapter card is firmly seated in its slot. For information on adapter card
installation and removal, see the “Completing the Installation” section on page 4-20.
–
Check the LEDs on the adapter card. Each adapter card has its own set of LEDs. For information
on these LEDs, see the “Reading the LEDs” section on page A-5.
–
Make sure that you have a version of software that supports the adapter card. Refer to the
documentation that was included with your adapter card.
• Adapter card is recognized, but interface ports do not initialize.

Make sure that the adapter card is firmly seated in its slot. For information on adapter card
installation and removal, see the “Completing the Installation” section on page 4-20.

boots but the console screen is frozen.

(b) 8 data bits.
(c) No parity generated or checked.
(d) 1 stop bit.
