5.2.2 POWER SUPPLY MODULE
The RFL 9785 power supply module is held in place by card guides at the top and bottom of the
chassis, and fits into a mating connector in the chassis motherboard. The top guide is made of
aluminum and has a locking lever to insure good heat transfer to a heat sink at the top of the chassis.
To remove the 9785 power supply module proceed as follows:
1. Lower the front cover of the RFL 9785.
2. Place the POWER switch(es) on the power supply I/O module at the rear of the chassis to the
OFF position.
The green power indicator(s) on the front of the power supply module(s) will go
out, indicating that the terminal is turned off.
3. Raise the locking lever at the top of the module to unlock the heat sink.
4. Lower the lever at the front of the module until the module connector disengages with the
motherboard connector.
5. Slide the module out of the chassis.
To replace the power supply module proceed as follows:
1. Using the label along the front of the chassis as a guide, determine the slot in the chassis where
the power supply is to be installed. Power supply modules can only be installed in the two left
hand slots of the 9785 chassis.
2. Line up the edges of the module circuit board with the grooves in the chassis.
3. Place the lever at the top of the module to the unlocked position and place the lower lever to
the fully closed position.
4. Slide the module into the chassis, and then push firmly until its connector is fully engaged with
the motherboard connector.
5. Lock the heat sink by setting the black lever to the full down position.
6. Place the POWER switch(es) on the power supply I/O module to the ON position.
The green power indicator(s) on the front of the power supply module(s) will light,
indicating that the terminal is turned on.
7. Raise the door on the front of the chassis to its vertical position, and turn the knobs clockwise
as far as they will go to lock the door.
