Installation Instructions (C515M)  
To replace the EPROMs in the CPU card:  
CAUTION: The pro-  
gramming in the  
1. Turn off power to the CM9502 card cage.  
2. Remove the CPU card from the card cage with the card extraction tool. Look-  
ing at the rear of the card cage, the CPU card is the second one from the right.  
CM9502 will be lost  
when you remove the  
CPU card. Note how  
your system is config-  
ured before turning off  
the power.  
When you remove the card, handle it only by its edges. Do not touch the  
goldfingers.  
3. Refer to Figure 1 and remove the old EPROMs. Use the tip of a screwdriver to  
pry up the ends of the EPROMs and remove them from their sockets.  
4. Install the new EPROMs. Do not touch the EPROM pins. Make sure the notch  
on the EPROM lines up with the notch on the socket (refer to Figure 1). Place  
the EPROM pins the socket and push down on the EPROM. Make sure the  
pins go into the socket and do not bend under the EPROM.  
5. Find resistor R21 (refer to Figure 1). If the value of the resistor is 100K ohm  
(brown, black, yellow stripes), replace it with the 3.3M ohm resistor (orange,  
orange, green stripes) included in the kit. If R21 is already a 3.3M ohm resis-  
tor, no modification is required.  
6. Replace the CPU card in the card cage and turn on the power.  
7. Reprogram the CM9502.
