Module Status LEDs
Card appears:
Green when the router is operating normally and when the self-test
is complete with no errors. (The Card LED remains green when a net-
work is down, when an interface slot is empty, when there is a fail-
ure of the cooling module or of one of two installed power supplies,
or when there is a temperature warning. These conditions allow the
other modules in the router to operate normally.)
Orange when the self-test is in progress, or when there is a failure of
the corresponding module after the self-test or during router opera-
tion.
• If a Card LED remains orange at the end of the self-test, either the
routing engine, one of the interface cards, or some other part of
the router is faulty. For more information, refer to chapter 3,
“Troubleshooting.”
• If a Card LED turns orange during router operation, there has
been a software failure. (The router’s Status LED will also turn
orange in this condition.) This condition will remain only a few
seconds until the router reboots (which will occur unless Auto
Reboot in the configuration has been disabled). For more informa-
tion, refer to chapter 3, “Troubleshooting.”
• If the Card LED is orange during router operation and none of the
Net Fail LEDs is lit, the card may not be seated properly. (The
Card LED flashes orange, and the Self-test LED flashes green.)
