Problems configuring the Pipeline
Pipeline User’s Guide Preliminary January 30, 1998 D-5
The start-up display indicates a power-on self test failure
If the start-up display indicates a failure in any of its tests, an internal hardware
failure has occurred with the unit. In this case, contact Ascend Communications,
Inc. Customer Support.
Problems configuring the Pipeline
There are two common problems associated with the Pipeline configuration
procedure:
• The communications program does not display a profile when you press
Ctrl-L.
• A profile appears when you press Ctrl-L, but it isn’t the Configure profile
shown in this manual.
If you see garbage characters on the screen, make sure that vt100 emulation is set
to the right speed (9600 bps).
No profile appears in your communications program
If no profile appears when you press Ctrl-L in your communications program,
one of these conditions could be causing the problem:
• Your Pipeline is not receiving power.
• Your Pipeline is not connected to the serial port of your computer.
• Your communications program is not configured correctly for your Pipeline,
or it is not communicating on the right port.
• There is a hardware problem with the Pipeline.
To diagnose and solve the problem, follow these steps:
1
Check the pwr LED on the front panel of the Pipeline.
If the pwr LED is not on, the unit is not receiving power. It may not be
connected to a power source. Continue to step 2.
If the light is on, continue to step 4.
2
Connect your Pipeline to a power source.
