Understanding How Environmental Monitoring Works
When the system has an alarm (major or minor), that indicates an overtemperature condition, the alarm
is not canceled nor is any action taken (such as module reset or shutdown) for 5 minutes. If the
temperature falls 5°C (41°F) below the alarm threshold during this period, the alarm is canceled.

Note Refer to the Cisco 7600 Series Router Module Installation Guide for additional information on LEDs,
including the supervisor engine SYSTEM LED.

1. Temperature sensors monitor key supervisor engine components including daughter cards.
2. A STATUS LED is located on the supervisor engine front panel and all module front panels.
3. The STATUS LED is red on the failed supervisor engine. If there is no redundant supervisor, the SYSTEM LED is red also.
