Troubleshooting Network Interfaces
To drop a particular T1 line to the test port, follow these steps:
Step 1
Enable Drop and Insert mode by entering the test trunk drop-insert on privileged EXEC command as
follows:
Router# test trunk drop-insert on t1port
Note
The t1 port is the particular T1 line that you wish to drop. T1 port numbers range
from 1 to 28.
Step 2
Disable the Drop and Insert mode after testing the T1 lines. We recommend that you disable Drop and
Insert mode to prevent accidental use of the push button on the CT3 card.
To disable Drop and Insert mode, enter the test trunk drop-insert off privileged EXEC command as
follows:
Router# test trunk drop-insert off t1 port
Troubleshooting Network Interfaces
For information about isolating problems with the network connections to your universal gateway, refer
to the publication
Internetwork Troubleshooting Guide available on Cisco.com and the Cisco
Documentation CD-ROM that shipped with the Cisco AS5400. For more information, see the “Related
Documentation” section on page -xiii in the Preface.
Flash Memory Installation
It is critical that the correct Flash memory SIMM modules be installed in the Cisco AS5400 and
Cisco AS5400HPX universal gateways. The Cisco AS5400 only supports 5V Flash memory SIMM
modules and the Cisco AS5400HPX only supports 3.3V Flash memory. In addition, system flash and
boot flash modules for the Cisco AS5400 are not interchangeable with those for the Cisco AS5400HPX.
Using the incorrect memory will cause the system to malfunction and may cause damage to the system
board or memory card. For installation instructions, refer to Appendix A,
“Replacing Flash Memory
SIMMs”
Cisco AS5400HPX Images
The Cisco AS5400HPX platform only supports Cisco IOS Software Release 12.2(2)XB images and
later. Problems may occur if images earlier than Cisco IOS Software Release 12.2(2)XB are loaded on
the universal gateway. For more information about unsupported images on the Cisco AS5400HPX, refer
to the Cisco AS5400 field notices on cisco.com at:
