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:

  • alarm —Displays environmental alarms.

– 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:

Router# show environment

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 1-1 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.

 

Table 1-1 Environmental Monitoring for Supervisor Engine and Switching Modules

Component
Alarm Type
LED Indication
Action

Supervisor engine temperature sensor exceeds major threshold

Major

STATUS LED red

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.

Note

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

Supervisor engine temperature sensor exceeds minor threshold

Minor

STATUS LED orange

Generates syslog message and an SNMP trap.

Monitors the condition.

Redundant supervisor engine temperature sensor exceeds major or minor threshold

Generates syslog message and an SNMP trap.

Major

STATUS LED red

If a major alarm is generated and the overtemperature condition is not corrected, the system shuts down after 5 minutes.

Minor

STATUS LED orange

Monitors the condition if a minor alarm is generated.

Switching module temperature sensor exceeds major threshold

Major

STATUS LED red

Generates syslog message and SNMP.

Powers down the module (see the “How to Power Modules Off and On” section for instructions).

Switching module temperature sensor exceeds minor threshold

Minor

STATUS LED orange

Generates syslog message and an SNMP trap.

Monitors the condition.
