Verifying proper operation
Meaning or action
The port is not transmitting or receiving packets. Check the
following:
•
Look at the LED for the other 10/100/1000 Ethernet port to
see if a link has been established with the remote port.
•
Verify that the connection to the other router has been
properly made. Also, make certain that the other router is
powered on and operating correctly.
•
Try using a different cable.
The module is not receiving power. Check the following:
•
Make certain that the module is installed properly. For more
information, refer to the module installation section in this
chapter that applies to your router model.
•
The module may not be receiving enough power. Dell
recommends installing power supplies in a fully redundant
configuration as described for each router model in this
chapter.
•
Check the Pwr LED on the management module. If it is on,
the management module may be preventing power from
getting to the interface module.
•
Enter the show chassis command at any level of the CLI to
determine if the management module recognizes the
presence of all power sources.
•
If you are using AC power supplies, see the entry for the AC
power supply LED in this table for more information.
The interface module may be in interactive mode. Check the
status of the module by entering the show module command at
any level of the CLI.
This LED will remain off until you have cabled the interface
module ports.
After cabling the ports, if this LED is still off, a link is not
established with the remote port. For more information, refer to
Table 18
on page 97.
