5 Locate the four captive screws on the PSU/fan controller behind the access panel as shown in

6 Turn each captive screw counter-clockwise, using a #1 Phillips screwdriver, to loosen all four captive
screws on the PSU/fan controller also shown in Figure 142.
7 Pull the PSU/fan controller out from the PSU control card access panel on the switch, by pulling
equally on the upper and lower handles.
Leave the ESD-preventive wrist strap permanently connected to the switch, so that the strap is always
available when you need to handle ESD-sensitive components.
