Cisco Catalyst 6500 Series Power Management

Power Management Overview

This section introduces the power management capabilities of the Catalyst 6500 series, including requirements for redundant power supplies and how the system handles different power configurations.

For comprehensive command syntax and usage, refer to the Cisco command reference documentation: Cisco IOS Command Reference.

Additional information and troubleshooting for Cisco Catalyst 6500 Series Switches can be found at: Cisco Catalyst 6500 Series Support.

Configuring Power Redundancy

The document explains how to enable or disable power redundancy modes (combined or redundant) using CLI commands. It details the effects of various power supply configuration changes on system operation and module status.

Key aspects covered include:

• Enabling/disabling redundancy modes.
• Impact of adding or removing power supplies with different wattages.
• System behavior during power supply failures.

Module Power Control

Instructions are provided for powering individual modules on and off using the CLI. This includes specific commands like power enable module and no power enable module.

Monitoring Power Status

The guide demonstrates how to use the show power command to display the current power status of system components, including total power, used power, available power, and the status of individual power supplies.

Power Cycling Modules

Information is given on how to power cycle (reset) line card modules using the hw-module module {mod #} reset command, which temporarily powers the module off and then back on.
