Troubleshooting Installation Problems Chapter 4 Starting and Configuring the Router • If the LNK LED is on (green), but the Ethernet port does not seem to be working properly, make sure that the port in question is configured properly and is not administratively shut down. If you have a working console connection, perform the following steps: - At the router prompt, enter show int fast0/0/0. If the port is administratively down, enter these commands to enable it: switch> configure terminal Enter configuration commands, one per line. router(config-if)# int fast0/0/0 router(config-if)# no shut router(config-if)# exit router(config)# exit router# End with CNTL/Z. - Check that the Ethernet port in question has a valid IP address assigned to it. For more information about configuring Ethernet ports, see the Cisco 10000 Series Router Line Card Configuration Guide. If the cable, connections, power, and configuration all check out, and you still cannot connect to the Ethernet port on the module, you probably need to replace the PRE. Contact the Cisco TAC for further assistance. Troubleshooting the Console Port Serial Connection If the terminal connected to the Cisco 10008 console port appears frozen or fails to work properly, check for the following problems: • Check the console cable and make sure it is properly connected to the correct console port on the PRE, and to your equipment at the other end. • Verify that you are using the proper type of cable and adapter. For additional information about cable pinouts, see the "Connecting a Video Terminal to the PRE Console Port" section on page 3-30. • To be sure the cable is not defective or broken, replace the cable with another high quality cable if possible. • Check that your terminal equipment is working properly and configured with the correct settings for the console port. The default console port settings are: - 9600 baud - 8 data bits - 1 stop bit - No parity - No flow control • Check the LEDs on the PRE to make sure that it is powered on properly. • If the cable, connections, power, and terminal settings are all acceptable and you still cannot connect to the console port on the module, you probably need to replace the PRE. Contact the Cisco TAC for further assistance. 4-14 Cisco 10008 Router Hardware Installation Guide OL-0659-13

Troubleshooting Installation Problems
•
If the LNK LED is on (green), but the Ethernet port does not seem to be working properly, make
sure that the port in question is configured properly and is not administratively shut down. If you
have a working console connection, perform the following steps:
–
At the router prompt, enter
show int fast0/0/0
. If the port is administratively down, enter these
commands to enable it:
switch>
configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
router(config-if)#
int fast0/0/0
router(config-if)#
no shut
router(config-if)#
exit
router(config)#
exit
router#
–
Check that the Ethernet port in question has a valid IP address assigned to it.
For more information about configuring Ethernet ports, see the
Cisco 10000 Series Router Line Card
Configuration Guide
.
If the cable, connections, power, and configuration all check out, and you still cannot connect to the
Ethernet port on the module, you probably need to replace the PRE. Contact the Cisco TAC for further
assistance.
Troubleshooting the Console Port Serial Connection
If the terminal connected to the Cisco
10008 console port appears frozen or fails to work properly, check
for the following problems:
•
Check the console cable and make sure it is properly connected to the correct console port on the
PRE, and to your equipment at the other end.
•
Verify that you are using the proper type of cable and adapter. For additional information about
cable pinouts, see the
“Connecting a Video Terminal to the PRE Console Port” section on page 3-30
.
•
To be sure the cable is not defective or broken, replace the cable with another high quality cable if
possible.
•
Check that your terminal equipment is working properly and configured with the correct settings for
the console port. The default console port settings are:
–
9600 baud
–
8 data bits
–
1 stop bit
–
No parity
–
No flow control
•
Check the LEDs on the PRE to make sure that it is powered on properly.
•
If the cable, connections, power, and terminal settings are all acceptable and you still cannot connect
to the console port on the module, you probably need to replace the PRE. Contact the Cisco TAC
for further assistance.
