4 Use the fan tray handle to pull the fan tray half-way out from the fan tray slot. This action
disconnects the fan tray from the switch power.
Wait for the fan blades to stop turning before continuing with this procedure.
WARNING!
Be sure that all fan blade motion has ceased before continuing to remove the fan tray.
5
Support the bottom of the fan tray with your free hand as you use the handle to slide the fan tray
completely out from the fan tray slot.
CAUTION
Be sure that both hands are used to support the weight of the fan tray during removal.
Leave the ESD-preventive wrist strap permanently connected to the switch so that it is always available
when you need to touch ESD-sensitive components.
