Removal and Replacement Procedures
This chapter provides subassembly/module-level removal and replacement procedures for the
Compaq Professional Workstation SP700.
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 just above the right top side of the side access panel
the rear of the workstation 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, reenter the original serial number through
Computer Setup.
NOTE: If a system board from another workstation is installed, POST recognizes the serial
number as a valid number.

  • Page 38: Scsi Guidelines For Installing Scsi Devices

    3-38 Removal and Replacement Procedures SCSI Guidelines for Installing SCSI Devices If you are installing a narrow SCSI device, you will need to attach a 68- to 50-pin SCSI adapter to the narrow SCSI device. A maximum of seven SCSI devices may be installed on each channel Each channel of the integrated dual Wide-Ultra SCSI controller requires that a unique SCSI ID (0-6 and 8-15) be set for each SCSI device installed.

  • Page 39: Scsi Guidelines For Optimizing Performance

    SCSI Guidelines for Optimizing Performance To maintain Ultra speeds, do not install more than four SCSI devices on each channel. For best performance, do not mix Wide-Ultra and narrow SCSI devices on either the same SCSI cable or the same channel. Because channel 1 of the integrated Dual Wide-Ultra SCSI controller is connected to the preinstalled Wide-Ultra SCSI hard drive in the removable hard drive cage, use channel 2 for any narrow SCSI devices.
