Verifying and Troubleshooting Line Card Installation
The following sections provide information about how to verify and troubleshoot line card installations:
Troubleshooting using Cisco IOS XR commands is briefly described in Configuring and Troubleshooting Line Card Interface Cards.
Initial Boot Process
Note |
All new line cards are designated as administratively down by default. Port Status LEDs are off until you configure the interfaces and use the no shutdown command. |
During a typical line card boot process, the following events occur:
- The line card receives power and begins executing initialization software.
- The line card performs internal checks, and prepares to accept the Cisco IOS XR software from the RSP.
- The RSP loads the line card with its Cisco IOS XR software.
To verify that the line card is working properly:
- Check that the Card Status LED is on (green) to verify that the card is operating normally.
- Check that the Port Status LED for the port of interest is on (green or blinking) to verify that the port is active. If the Port Status LED is not on, verify that the associated interface is not shut down.
- If one of the conditions above is not met, see Advanced Line Card Troubleshooting to identify any possible problems.
Line Card LEDs
You can use the Line Card Status LED or the Port Status LEDs on the line card front panels to verify proper operation or troubleshoot a failure. The following table describes the port and card status LEDs.
Port Status LEDs (one per port) |
|
Green |
Port state is up and a valid physical layer link is established. |
Blinking |
Line activity is occurring. The LED blinks green-amber-green. |
Red |
Port is enabled, but there is a link loss or SFP/XFP failure. |
Off |
Port is administratively shut down. |
Card Status LED (one per card) |
|
Green |
Line card has booted properly, and is ready to pass or is passing traffic. |
Steady Amber |
Line card boot process is underway. When the Cisco IOS XR software finishes loading, the LED turns green. |
Blinking Amber |
Software configuration error has occurred that prevents the line card from passing traffic. It is possible that the line card is still passing traffic, but there is some degradation. |
Red |
Line card has encountered a hardware error, and is not passing traffic. |
Off |
Line card is powered off. The LED might turn off momentarily when switching between the states described above, although the line card has not powered off. |
Modular Port Adapter LEDs
The modular port adapters have two types of LEDs: an A/L LED for each individual port and a STATUS LED for the modular port adapter. The following table describes the modular port adapter LEDs.
Color |
State |
Meaning |
---|---|---|
A/L LED (one per port) |
||
Off |
Off |
Port is administratively shut down. |
Green |
On |
Port is administratively enabled and the link is up. |
Red |
On |
Port is administratively enabled and the link is down. |
Blinking |
On |
Line activity is occurring. The LED blinks green-amber-green. |
STATUS LED (one per card) |
||
Off |
Off |
Modular port adapter power is not enabled. |
Red |
On |
Modular port adapter has encountered an hardware error. |
Amber |
On |
Modular port adapter power is on and there is activity. |
Green |
On |
Modular port adapter is ready and operational, there is no activity. |
Troubleshooting the Installation
Note |
All new line cards are designated as administratively down by default. Status LEDs are off until you configure the interfaces and use the no shutdown command. |
If the Card Status LED or a Port Status LED does not go on, there is either a problem with the line card installation or a hardware failure. To verify that the line card is installed correctly, follow these steps:
-
If a Port Status LED fails to go on (no activity), but the Card Status LED is on, verify that the initialization sequence has completed successfully. If this is the case, verify that the interface is not shut down. If the interface is not shut down, suspect a circuitry problem with the Port Status LED and contact a service representative for further assistance.
-
If the Card Status LED fails to go on, check the router connections as follows:
-
Verify that the line card board connector is fully seated in the backplane. Loosen the captive installation screws and firmly pivot the ejector levers toward each other until both are parallel to the line card front panel. Tighten the captive installation screws.
-
Verify that all power cords and data cables are firmly connected at both ends.
-
Verify that all components on the card are fully seated and secured to their sockets.
After the line card reinitializes, the Card Status LED on the line card should go on. If the Card Status LED goes on, the installation is complete; if the Card Status LED does not go on, proceed to the next step.
-
-
If the Card Status LED still fails to go on, remove the line card and try installing it in another available line card slot.
-
If the Card Status LED goes on when the line card is installed in the new slot, suspect a failed backplane port in the original line card slot.
-
If the Card Status LED still does not go on, halt the installation. Contact a service representative to report the faulty equipment and obtain further instructions.
-
If an error message displays on the console terminal during the line card initialization, see the appropriate reference publication for error message definitions.
If you experience other problems that you cannot solve, contact a Cisco service representative for assistance.
Note |
If you perform online insertion or removal of the SFP or XFP module without shutting down the interface, a warning message is displayed on the console device. |
