receptacle on the top right corner of the switch.

4 Use the fan tray handle to pull the fan tray half-way out of the fan tray slot (see Figure 79 ). 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 of the fan tray slot.
CAUTION
Use both hands to support the weight of the fan tray during removal.
