Ascend Pipeline 130
Troubleshooting Guide
Connecting to your router
- Connect to router. (See the Ascend Pipeline 130 Wiring Diagram.)
- Establish a session to the router: Either telnet to the router from a host on the same IP network or hook up an out of band console.
If you can't get the console connected:
- Verify terminal settings in VT100 software.
- Make sure cable is *NOT* a null modem cable.
- Press Cntl-L to refresh screen.
- Menu screen should come up.
- Verify that the IP Address is correct.
Ethernet::Mod Config::Ether Options::IP Adrs=LAN.LAN.LAN.LAN/24
(where LAN.LAN.LAN.LAN is the IP address of the router).
- Verify that the Default Gateway is correct.
Ethernet::Static Rtes::Default::Gateway=SER.SER.SER.1
(where SER.SER.SER.1 is the first 3 octets of your serial ip and .1)
Verifying the Line is up
- Check the WAN light, it should be lit for an active WAN session.
- If the WAN light is not lit, connect to your router.
- Check the uppermost middle status window for the word Link. Next to the word Link should be status of the ISDN line as well as the T1 line. Below is a picture of the status windows.
- Find the status of your line in the following table.
| Status |
Definition |
| CARRIER |
The T1 line is receiving the correct framing, normal condition. |
| YELLOW |
The Pipeline is detecting this alarm because it may be sending out a signal that the switch cannot recognize. |
| BLUE |
The Pipeline is detecting an "all ones" signal from the WAN. |
| RED |
No signal detected from the WAN. |
| LOOPBACK |
Loopback active either manually from menus or remotely from inband signal. |
The Link should say carrier.
- If it says LOOPBACK, from the Main Edit Menu check Nailed T1::Mod Config::Loop Back=Normal
- If it says RED, check the physical connections.
- It is also important to make sure that the FR Prof specified in Ethernet::Connections::FR::Encaps Options has the same name as is specified in Ethernet::Frame Relay
- In Ethernet::Frame Relay::FR::Nailed Grp must be equal to 3 and Data Svc should be equal to 64K
- The Nailed Grp in Ethernet::Frame Relay::FR must match the Nailed T1 Group specified in Nailed T1::Mod Config
The unit will still not connect:
