Maintenance and Field Replacement
E.1 Considerations
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 power supply or fans may not be functional).
Before you begin, refer to the Arista Networks document Safety Information and Translated Safety Warnings available at: http://www.arista.com/support/docs/eos.
Note Descriptions for the removal and replacement of power supplies and fans are for a representative power supply or fan. Locations of status indicator LEDs may differ. Refer to the front and rear panel illustrations of your device to locate the appropriate LED.
