5.2 REMOVAL AND REPLACEMENT
The following paragraphs provide procedures to be used when removing and replacing RFL 9780
circuit board modules and I/O modules.
5.2.1 CIRCUIT BOARD MODULES
All RFL 9780 front panel circuit board modules are held in place by card guides at the top and bottom
of the chassis, and fit into mating connectors in the chassis motherboard. To remove any RFL 9780
front panel module, with the exception of the power supply module, proceed as follows:
1. Lower the front cover of the RFL 9780.
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. Lower the lever at the front of the module until the module connector disengages with the
motherboard connector.
4. Slide the module out of the chassis.
To replace a circuit board module, with the exception of 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 module is to be installed.
2. Line up the edges of the module circuit board with the card guides in the chassis.
3. Place the lever in the full up position.
4. Slide the module into the chassis, and then push firmly until its connector is fully engaged with
the motherboard connector.
5. 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.
6. 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.
