Installation Best Practices

When installing the switch, follow these best practices:

•Plan your site configuration and prepare the site before installing the chassis.

•Verify that you have the appropriate power supplies for your chassis configuration.

•Install the chassis following the rack and airflow guidelines presented in this guide.

•Verify that the chassis is adequately grounded.

Initialization Best Practices

When the initial system boot is complete, verify the following:

•Power supplies are supplying power to the system.

•Fan modules are operating normally.

•The system software boots successfully.

Switch Operation Best Practices

To ensure proper operation of your switch, take the following actions:

•Make a copy of the running configuration to CompactFlash for a safe backup.

•Always enter the copy running-configstartup-configCLI command after you modify the running configuration and ensure that the system is operating properly.

•Never use the init system CLI command unless you understand that you will lose the running and startup configuration as well as the files stored on bootflash:.

•Keep backup copies of the running kickstart and the system images on CompactFlash.

Power Supply Conditions

The two LEDs on each power supply indicate the power status for each power supply. To determine the current status for a power supply unit, note which LED is on, blinking, or off and refer to Table E-1.
