Environmental Monitoring Overview
Environmental monitoring of chassis components provides early-warning indications of possible component failures, which ensures a safe and reliable system operation and avoids network interruptions. This section describes the monitoring of these critical system components, which allows you to identify and rapidly correct hardware-related problems in your system.
How to Determine Sensor Temperature Thresholds
The system sensors set off alarms based on different temperature threshold settings. Use the show environment alarm threshold command to display the sensor temperature thresholds:
How to Monitor the System Environmental Status
To display system status information, enter the show environment [ alarm | cooling | status | temperature ] command. The keywords display the following information:
– status —Displays alarm status.
– thresholds —Displays alarm thresholds.
- cooling —Displays fan tray status, chassis cooling capacity, ambient temperature, and per-slot cooling capacity.
- status —Displays field-replaceable unit (FRU) operational status and power and temperature information.
- temperature —Displays FRU temperature information.
To view the system status information, enter the show environment command:
Information About LED Environmental Indications
The LEDs can indicate two alarm types: major and minor. Major alarms indicate a critical problem that could lead to the system being shut down. Minor alarms are for informational purposes only, giving you notice of a problem that could turn critical if corrective action is not taken.
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.
Table 16-1 lists the environmental indicators for the supervisor engine and switching modules.
Note See the Catalyst 6500 Series Switch Module Installation Guide for additional information on LEDs, including the supervisor engine SYSTEM LED.

---|---|---|---|
Supervisor engine temperature sensor exceeds major threshold |
Generates syslog message and an SNMP trap. If there is a redundancy situation, the system switches to a redundant supervisor engine and the active supervisor engine shuts down. If there is no redundancy situation and the overtemperature condition is not corrected, the system shuts down after 5 minutes. |
||
Supervisor engine temperature sensor exceeds minor threshold |
|||
Redundant supervisor engine temperature sensor exceeds major or minor threshold |
|||
If a major alarm is generated and the overtemperature condition is not corrected, the redundant system shuts down after 5 minutes. |
|||
Generates syslog message and SNMP. Powers down the module (see the “How to Power Modules Off and On” section for instructions). |
