Device Hardware Guidelines
Use the recommendations in this section to ensure the proper installation, initialization, and operation
of the device. This section includes the following topics:
•Installation, page D-2
•Initialization, page D-2
•Device Operation, page D-2

Installation

When installing the device, follow these best practices:
•Plan your site configuration and prepare the site before installing the chassis.
•Verify that you have the appropriate power supplies and fan trays for your chassis configuration. For
each chassis, each module must have the same airflow direction. Either all modules have
front-to-back airflow (no black stripe on the front) or all have back-to-front airflow (black stripe on
the front). If you have modules that use different airflow directions in the same chassis, you will see
an error message.
•Install the chassis following the rack and airflow guidelines in this publication.
•Verify that the chassis and DC power supplies are adequately grounded.

Initialization

When the initial system boot is complete, verify the following:
•Power supplies are supplying power to the system.
•Fan trays are operating normally.
•The system software boots successfully. See the Cisco Nexus 2000 Series Fabric Extender Software
Configuration Guide for information about booting the system and initial configuration task.

Device Operation

To ensure proper operation of your device, do the following:
•Make a copy of the running configuration to CompactFlash for a safe backup.
•Always enter the copy running-config startup-config command after you modify the running
configuration and ensure that the system is operating properly.
•Never use the init system 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.
