Motorola CPCI-6115 用户手册

The PMC 2 I/O voltage key should be installed in the appropriate position for the 
PMC to be used. If installed in the +5 V position, PMC 2 is set to +5 V I/O. If installed 
in the +3.3 V position, PMC 2 is set to +3.3 V I/O. If the PMC accepts either key, 
install the key in the +3.3 V position (factory default). +3.3 V I/O voltage is required 
for any PCI/PCI-X operation faster than 33 MHz.

6. Slide the edge connector of the PMC module into the front panel opening from 

behind and place the PMC module on top of the baseboard. The four connectors on 
the underside of the PMC module should then connect smoothly with the 
corresponding connectors (J11/12/13/14) or (J21/22/23/24) on the CPCI-6115.

7. Insert the four short Phillips screws, provided with the PMC, through the holes on 

the bottom side of the CPCI-6115 into the PMC front bezel and rear standoffs. 
Tighten the screws.

8. Reinstall the CPCI-6115 assembly in its proper card slot. Be sure the module is well 

seated in the backplane connectors. Do not damage or bend connector pins.

9. Replace the chassis or system cover(s), reconnect the system to the AC or DC 

power source, and turn the equipment power on.

If the PMC provides rear I/O, refer to 

 for the pin 

assignments. Connectors on the CPCI-6115-MCPTM transition module provide rear panel 
access to these signals.
