About the fan tray
The 8900 platform has a removable fan tray that is designed to maintain airflow throughout the chassis.
You can change or replace the fan tray as part of the routine maintenance of the unit, or in the event of a
fan failure. The fans in the fan tray run constantly while the unit is on. Over time, the fans can wear out,
requiring you to replace the fan tray.
Important: This product is sensitive to electrostatic discharge (ESD). F5 Networks recommends that you
use proper ESD grounding procedures and equipment when you install or maintain the unit.
