1Attach the ESD-preventive wrist strap to your wrist and connect the metal end to the ground receptacle on the top-left corner of the switch chassis.

4Use 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.

5Support 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.
