Upgrading DRAM on the CIP2 11
Checking the DRAM Upgrade
Checking the DRAM Upgrade
After you upgrade DRAM, reinstall the CIP2, and reattach cables, verify system operation by
observing the LED states and the console display. When the system has reinitialized all interfaces,
the enabled LED on the CIP2 (and on all other interface processors) should go on. The console
screen will also display a message as the system discovers each interface during its reinitialization.
When you remove and replace interface processors, the system provides status messages on the
console screen. These messages are for information only.
Verify that the CIP2 is installed correctly as follows:
Step 1
While the system reinitializes each interface, observe the messages on the console display
and verify that the system discovers the CIP2 as follows:
•
After you replaced the CIP2, the system should recognize the interface and place it in
the same state (up or down) it was in before you removed the CIP2.
•
If the router fails to boot, displays an error message, or fails to recognize the CIP2,
remove the CIP2 and reboot.
Step 2
When the reinitialization is complete, verify that the enabled LED on the CIP2 goes on and
remains on. If it does, proceed to Step 5. If it does not, proceed to the following step.
Step 3
If the enabled LED on the CIP2 fails to go on, the CIP2 card edge connector might not be
fully seated in the backplane. Proceed as follows:
•
Loosen the captive installation screws, then firmly push the ejector levers inward
(toward the interface port) until both are parallel to the CIP2 faceplate.
•
Tighten the captive installation screws.
•
After the system reinitializes the interfaces, the enabled LED on the CIP2 should go on.
If it does not, proceed to Step 4. If it does, proceed to Step 5.
Step 4
If the enabled LED still fails to go on, remove the CIP2 and try installing it in another
available interface processor slot.
•
If the enabled LED goes on when the CIP2 is installed in the new slot, there could be a
failed backplane port in the original interface processor slot.
•
If the enabled LED still does not go on, do not proceed with the installation. Contact a
Cisco service center to report the faulty equipment and obtain further instructions.
(Instructions for obtaining additional technical assistance are provided in the note on the
last page of this document.)
Step 5
Use the show interfaces or show controllers cbus EXEC commands to verify the status
of the interface. (For complete descriptions of the show commands, refer to the appropriate
configuration and command reference publications for your version of Cisco IOS
software.)
If an error message is displayed on the console terminal, refer to the System Error Messages
publication for error message definitions. If you need troubleshooting information specific to your
router, refer to the troubleshooting chapter in the appropriate router hardware publication that
shipped with your router. If you need more general troubleshooting information, refer to the
Troubleshooting Internetworking Systems publication.
All of these publications are available on the Cisco Connection Documentation, Enterprise series
CD-ROM, or as printed copies.
If you are still unable to resolve the problem, refer to the note on the last page of this publication for
information on obtaining technical assistance and support.
