HP Kayak XA-s Series 02 Manual

Familiarization Guide
HP Kayak XA-s
HP Kayak PC Workstation Family
This guide is for experienced technicians who have already
completed the training course on the HP Kayak PC
Workstation family. In particular, it assumes that the reader
is already familiar with the HP Kayak XA-s Minitower, XU
and XW PC Workstations, which share many features with
the HP Kayak XA-s Desktop PC Workstation.
This document serves as a self-paced familiarization guide
to the new desktop package, designed to train you for repair
of the computer, and only contains repair-specific
information. For information on the installation of
accessories, see the User’s Guide and the online documents
that are supplied with the computer.

Step 13: Adding/Replacing DIMMs
Upgrading Main Memory Modules
Main memory upgrades are available in 32 MB, 64 MB, 128 MB and 256 MB
ECC SDRAM modules. It is important to note that the 32 MB, 64 MB and
128 MB modules are non-buffered ECC SDRAM modules, while the 256 MB
modules are registered ECC SDRAM modules.
NOTE Non-buffered and registered ECC modules are not compatible with each
other, and cannot be mixed. See the table below for DIMM compatibility
rules.
1. All DIMMs will function as Non-ECC.

No No Yes
The PC Workstation has 64 MB of non-ECC SDRAM main memory
installed in one DIMM slot. Can a 256 MB ECC SDRAM memory
module be added to a second DIMM slot in order to upgrade the
memory?
No. To upgrade the memory, it is possible to add 64 MB or
128 MB memory modules (either ECC or non-ECC) to the
other 2 DIMM slots (up to a maximum of 320 MB). Alterna-
tively, you may remove the existing 64 MB memory module
and install up to 3 ✕256 MB memory modules, for a total of
768 MB.

Step 14: Removing/Reconnecting Other Cables
Step 14: Removing/Reconnecting Other Cables
Step 15: Removing/Reinstalling the System Board
Disconnect and remove all
other cables (for example,
power cables, CD-ROM audio
cable, external start cable, LCD
status panel cable, etc.)
Open and remove the gate
on the right-hand side of the
chassis as shown.
Remove the two quick-release
screws on the backplane of the
chassis.
Using the pull-loop at the back right-
hand side, pull the system board towards
the front of the chassis until the three
tabs of the CPU guide slide out of their
slots on the bottom of the chassis.
Remove the system board through the
open chassis gate.
Reinstalling the system board: To reinstall the system board, reverse the above steps.
