Chapter 4 Troubleshooting
Identifying Startup Problems
Step 2 Check that the LEDs on the supervisor engine light as follows:
•The STATUS LED flashes orange once and stays orange during diagnostic boot tests. It turns green when the module is operational (online). If the system software is unable to start up, this LED stays orange.
•The SYSTEM LED turns green, indicating that all chassis environmental monitors are reporting that the system is OK. If one or more environmental monitor reports a problem, the SYSTEM LED is orange or red.
•The ACTIVE LED turns green, indicating that the supervisor engine is operational and active. If the supervisor engine is in standby mode, the ACTIVE LED is orange.
•Each LINK LED flashes orange once, stays orange during diagnostic boot tests, and turns green when the module is operational (online). If no signal is detected, the LINK LED turns off. The LINK LED blinks orange if the port is bad.
If any LEDs on the supervisor engine front panel are red or orange, see the “Troubleshooting Modules” section on page
If you have a redundant supervisor engine, refer to the Cisco 7600 Series Internet Router Software Configuration Guide or the Cisco 7600 Series Internet Router IOS Software Configuration Guide publications for descriptions of how the redundant supervisor engine comes online and how the software images are handled.
For a complete description of the supervisor engine LEDs, refer to the
Cisco 7600 Series Internet Router Module Installation Guide.
Step 3 Verify that the STATUS LEDs on the supervisor engine and on each switching module are green when the supervisor engine completes initialization. This LED indicates that the supervisor engine or switching modules are receiving power, have been recognized by the supervisor engine, and contain a valid Flash code version. This LED does not indicate the state of the individual interfaces on the switching modules. If a STATUS LED is red or orange, see the “Troubleshooting Modules” section on page
Step 4 If the boot information and system banner are not displayed, refer to the Cisco 7600 Series Internet Router Module Installation Guide to verify that the terminal is set correctly and that it is connected properly to the supervisor engine console port.
