Installing Additional DRAM Memory
Appendix E
Installation Procedure
Caution
The integrated circuit components in these products can be
damaged by electrostatic discharge. All work must be done by
a trained technician at a static-free workstation.
The SO DIMM modules are fragile. Care must be taken to not
bend or twist them during installation.
Tools Required
You will need the following tools to access the controller and install the SO
DIMM modules:
•
a grounding wrist strap and static-free workstation; and
•
a #0 (small) Phillips screwdriver.
SO DIMM
Installation
Requirements
Ensure that the following requirements are met.
•
SO DIMM modules must be installed in pairs with each module in a
pair being identical.
•
The SO DIMM modules being installed must be of the same type and
speed, but not necessarily size, as the pre-installed modules.
Installation Steps
1. At a static-free workstation, place the HP VXI Pentium Controller on
its left side such that the front panel is facing you and the sheet-metal
cover with its bar-coded serial number is on the far edge away from
you.
2. Attach the grounding strap to your wrist and take appropriate
anti-static precautions during the rest of this procedure.
3. With the #0 Phillips screwdriver, remove the eight (8) Phillips-head
screws holding the sheet-metal cover to the chassis. Do not lose these
very small screws. They will be needed to re-attach the cover.
4. Remove the sheet-metal cover and set it aside.
The CPU sub-module printed-circuit board is attached to the main I/O
base board in the upper-right corner of the unit. Two memory banks,
each with two SO DIMM sockets, are located on the CPU sub-module
just above the CPU cooling fan. The right memory bank will already
be occupied by the pre-installed SO DIMM modules. The new SO
DIMM modules are to be inserted into the left memory bank.
5. Carefully remove the first SO DIMM module from its packaging.
Take care to handle it only by its non-conductive edges and to not
touch the pin-connectors.
