Install the CFM Module

Publication 1771Ć6.5.99 - December 1995

Your CFM module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. The maximum current
drawn by the CFM module is 1.0A.

Add this value to the requirements of all other modules in the I/O
chassis to prevent overloading the chassis backplane and/or
backplane power supply.

!

ATTENTION: When using a 1771-P7 or 1771-PS7
power supply to power an I/O chassis, you cannot
place more than four CFM modules in this chassis.

The interaction between the four CFM modules and the
1771-P7 or 1771-PS7 power supply (not 16A limit)
prevents the power supply from powering up.

You check or set these jumpers:

module operation jumper

input channel jumpers

Check the Module Operation Jumper

Important: Make sure the module operation jumper is in the

CFM position (default setting).
