critical, major, or
minor alarm.
Cisco 6260 Hardware Installation Guide
5-4
Steps to Take
For a console problem, check the terminal settings against the list of settings in the
1.
a Console Terminal" section on page 3-21
page
4-20.
2.
For a Telnet problem:
If you are connecting to the Cisco 6260 through the Ethernet interface, check the
–
configuration of your LAN for both the Cisco 6260 and the Telnet source.
–
If you are connecting to the Cisco 6260 through an ATM interface, make sure that PVCs
are set up between the two devices and that the map-list is correctly configured. Enter
the command show running-config to display this information.
If the Telnet source and the Cisco 6260 are on different networks, make sure static
–
routes are configured at both ends so that the two devices can communicate. To check,
use the ping command to ping each device from the other (that is, ping the Cisco 6260
from the Telnet source, and ping the Telnet source from the Cisco 6260). Alternatively,
ping your default gateways from each end of the connection.
3.
For both console and Telnet problems:
Check the cabling and connectors between the terminal or Telnet source and the
–
Cisco 6260. See
Appendix C, "Connector and Pinout Specifications,"
–
Press the Reset button on the NI-2 card faceplate to reset the card.
If the problem persists, replace the NI-2 card.
–
Enter the command show facility-alarm status. Note the affected slot and port, if any, and
1.
the description of the problem.
If no slot number is indicated, enter show environment all and examine the results for an
2.
indication of which FRU is at fault. Refer to the
page 5-8
for instructions on troubleshooting that FRU.
3.
If ATM0/0, ATM0/1, ATM0/2, or ATM0/3 is indicated:
Enter a show int command for the interface (for example, show int atm0/1). Results
–
may indicate a SONET problem (Loss of Signal, for example). Refer to the
Problems" section on page 5-8
Enter show controllers commands for all trunk and subtending ports. (The ports are
–
atm0/1, atm0/2, and, in a DS3 system, atm0/3.) For example, show controllers atm0/1.
In the resulting display, check that the framing mode is set to the same value on this
interface as at the other end of the connection. Also check that cell payload scrambling
is on (on E3 interfaces only).
If a line card slot is indicated, consult the
