Compaq Professional Workstation AP500 Maintenance and Service Guide
Chapter 3
Removal and Replacement Procedures
This chapter provides subassembly/module-level removal and replacement procedures for the
Compaq Professional Workstation AP500.
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 top right side of the workstation 1 and also on the rear
of the chassis 2.
For asset control, the serial number is also embedded in the EPROM on the system board. If the
system board is replaced with a spare part from Compaq, an invalid serial number condition will
be reported during POST. To clear the condition, use Compaq Softpaq SP8410. It is located at:
http://www.compaq.com/support/files/workstations/us/software/674.html.
NOTE: If a system board from another workstation is installed, POST recognizes the serial
number as a valid number.
