Removal and Replacement Procedures

This chapter provides subassembly/module-level removal and replacement procedures for the
Compaq Professional Workstation AP400.
After completing all necessary removal and replacement procedures, run the Compaq Setup and
Diagnostics program to verify that all components are operating properly.

Serial Number

Provide the computer serial number to Compaq whenever you request information or order spare
parts. The serial number is located on the right side of the workstation cover
rear of the chassis above the fan .
For asset control, the serial number is also embedded in the EPROM on the system board with
tray. If the system board with tray is replaced with a spare part from Compaq, an invalid serial
number condition will be reported during POST. To clear the condition, reenter the original
serial number through Computer Setup.
NOTE: If a system board with tray from another workstation is installed, POST recognizes the
serial number as a valid number.
