23.5 OC3 Card Troubleshooting

OC3 card problems could indicate a number of possible causes, including:
• Misconfigured IP parameter at the far end
• Faulty cabling between the OC3 LAN port and the LAN
• T1 or E1 network failure
• Improper network configuration
• Improper OC3 card configuration
Typically, a problem is indicated by the inability to route IP traffic to/from or through the OC3
card. You can perform numerous tasks to isolate the trouble and clear it. When troubleshooting
problems on IP communications through an OC3 card, follow this general sequence:
1. The OC3 card performs a self-test on power-up. A "healthy" card will have a green LED
lit on the front panel. Do not proceed with further steps until a green LED is
present.Ensure that the card is both in-service and displaying a green LED.
2. Facility protection switch. If either the electrical facilities and/or the Ethernet facilities are
failed, execute a facility protection switch to utilize the other fiber.This will eliminate the
currently active logical port, the in-use SFP and the fiber cable.
3. Verify that the T1 network is working properly by checking for current CGA-Red and
CGA-Yellow alarms. If only the faceplate facilities are affected, make sure that the cable
to the T1 / E1 port is secure and has not been compromised.
4. Execute loopback commands on the embedded T1 facilities to assure that the alarm clear
on the affected port.
5. If the OC3 card is determined to be faulty, replace it and return the faulty unit for repair
to the location specified by your distributor.
