Removing and Replacing Field Replaceable Units

• Removing a DHW42 asynchronous communications option
• Removing the CPU module
• Replacing the CPU module
• Removing the power supply

Note

Unless otherwise specified, you can replace a FRU by reversing the

steps described in the removal procedure.

Table 3–1 lists the major FRUs in the BA42B Enclosure. It also gives the

order numbers for the FRUs and a reference to a section in this chapter

that gives information on how to replace the FRU. Refer to the

VAX 4000

BA42B Enclosure System Options

manual for more information about options.

Appendix C gives a complete list of the spare parts for the BA42B Enclosure.

Figure 3–1 shows the locations of the major FRUs in the BA42B Enclosure.

Caution

• Only qualified personnel should remove or install the FRUs.
• Before you remove or install the FRUs, turn off the system and

disconnect the power cord.

• Static electricity can damage integrated circuits. Wear a wrist

strap and place an antistatic mat under the system when working

with the internal parts of the system unit.

You must have the following tools to replace the FRUs in a BA42B-based VAX

system:
• A number 1, Phillips screwdriver
• A blade screwdriver
