Next you will install either an MFC-8310 or an MFC-8310-N controller card. Refer to the appropriate section for installation instructions for your specific controller card.
Installing the Controller Card
Use the following procedure to install the MFC-8310 controller card component of the CFM-8310:
Figure 11. MFC-8310 Fan Controller Card and Unscrewed Retaining Screw
1.With the frame door open, unscrew the MFC-8310 Card Retaining Screw (Part No. 850-040) enough to eliminate any protrusion into the card guide slot on the right of the screw. If necessary, remove any cards from the frame that would interfere with easy access and lines of sight.
2.Insert the MFC-8310 frame controller card, with the component side out as shown in Figure 11, into the card guides along the dividing wall between slot 10 and the PS- 8300 section of the frame, ensuring the card does not touch the Card Retaining Screw.
3.Slide the card in the slot until firmly seated and so the Card Retaining Screw hole on the bottom front edge aligns with the mounted nut beside the bottom guide slot.
4.Tighten the Card Retaining Screw through the mounted nut and the MFC-8310 Card Retaining Screw hole, to ensure the card does not move from the slot.
5.Close the door, power up the frame, and check the operation of the fans. If the fans do not operate, verify that the MFC-8310 is seated properly in the frame backplane and is aligned to the Fan PCB when the door is closed.
This completes the installation of the MFC-8310 controller card for the CFM-8310 Cooling Fan Module. Next you will learn the general functions and controls available on the MFC-8310 controller card.
Functions of the Controller Card
The MFC-8310 controller card component of the CFM-8310 performs several functions:
•Monitors frame power usage and sets the fan speed accordingly (higher power consumption requires higher fan speed for adequate cooling). The fans always run at maximum speed for 5
