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 e ngine 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 4-6.
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 interfa ces on the
switching modules. If a STATUS LED is red or orange, see the “Troubleshooting
Modules” section on page 4-6.
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 setcorrectly and that it is connected properly to the supervisor engine
console port.
