2.2 Procedure - PPC700 with 1 and 2 PCI slots
The procedure for devices with 2 PCI slots (5PC720.1043-01, 5PC720.1214-01, 5PC720.1505-
01, 5PC720.1505-02) is explained step-by-step in the following example (5PC720.1505-01).
• Disconnect the power supply to the Panel PC 700.
• Touch the housing or ground connection (not the power supply!) in order to discharge any
electrostatic charge from your body.
• Loosen the screws on the fan kit cover (using Torx screw driver size 10) and remove the
cover.
• If a PCI card is in place, it must be removed before moving on to the next step.
• There are two arrows on the fans that indicate the direction of air flow and the direction
of fan rotation.
