X.25 PAD-2
5. Troubleshooting
5.1 Things to Check First
If you have difficulty with your X.25 PAD-2, here are
some things to try:
• Check the PAD-2’s LED indicators. Compare their
current states with the information in Chapter 4 .
• Make sure the PAD-2 is powered. Is the POWER
LED lit? If not, check the power-supply connections
and make sure the AC outlet is working.
• Make sure that all of the cables are properly
connected to the PAD-2.
• Make sure that all equipment connected to the
PAD-2 is powered and operating normally.
• Make sure that the PAD-2 and the packet-switched
device it’s communicating with are configured
properly for your application and for interaction
with the local equipment attached to channels 2
and 3. Refer to the
Packet Switching Guide .
If you can’t determine what’s causing the problem,
power the PAD-2 OFF and back ON again. If the
problem persists, call Black Box Technical Support.
