Upgrading the VAX 4000 Model 100 System
2.5 Replacing the CPU Module
22. To remove the CPU module, follow these steps.
Caution
Ensure that you do not damage any of the CPU module components by
exerting too much force on them.
a. Press the two spring clips (marked by arrows in Figure 2–21) that
secure the CPU module in position. The CPU module moves forward
under the tension of the connector gaskets. If necessary, slide the CPU
module back until it disengages from the ten keyhole cutouts (refer to
Figure 2–21).
b. Use your finger, in the semicircular cutout on the front edge of the
CPU module, to lift up the front edge of the CPU module (refer to
Figure 2–21).
c. While supporting the front of the CPU module with one hand, guide
the connectors on the back of the CPU module out of the corresponding
cutouts on the back of the enclosure.
d. Remove the CPU module from the enclosure.
