Maintenance and Field Replacement

This section discusses the following topics:

Considerations

Review the following considerations when installing the device.

  • The Supervisor card is field-replaceable.
  • All fans and power supplies are hot-swappable.
  • The switch can be running while a power supply is being installed or removed, but the power supply being replaced must not be connected to a power source.
  • All slots must be filled or covered with a blank for operation (even though the power supply or fans may not be functional).
  • Before you begin, refer to the Arista Networks document Safety Information and Translated Safety Warnings: https://www.arista.com/en/support/product-documentation.

     

    Note: Descriptions for removing and replacing power supplies and fans are for a representative power supply or fan. Locations of status indicator LEDs may differ. Refer to your device's front and rear panel illustrations to locate the appropriate LED.
