Understanding How Environmental Monitoring Works

Using the CLI to Power Cycle Modules

From global configuration mode, enter the power cycle module slot command to power cycle (reset) a
module; the module powers off for 5 seconds and then powers on.

Determining System Power Requirements

System power requirements are dependent on the size of the power supply. You could have configuration
limitations when using the 1000 W and 1300 W power supplies depending on the size of chassis and type
of modules installed. For information about power consumption, refer to the Release Notes for the
Catalyst 6000 Family Switches and Cisco 7600 Internet Router for Cisco IOS publication at this URL:

Understanding How Environmental Monitoring Works
Environmental monitoring of chassis components provides early warning indications of possible
component failure to ensure safe and reliable system operation and avoid network interruptions. This
section describes the monitoring of these critical system components, enabling you to identify and
rapidly correct hardware-related problems in your system.

Using CLI Commands to Monitor System Environmental Status

Enter the show environment [alarm | status | temperature] command to display system status
information. The keywords display the following:

Understanding 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), indicating an overtemperature condition, the alarm is
not canceled or 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.
