Important Guidelines For Dimm Installation; Installing Dimm Modules - Compaq AP500 - Professional - 128 MB RAM Reference Manual

Important Guidelines for DIMM Installation

When installing DIMMs, you MUST follow the following guidelines:
Use only 32-, 64-, 128-, or 256-MB, Registered 100-MHz Error
Checking and Correcting (ECC) SDRAM DIMMs.
Registered DIMMs must be used.
DIMMs must have a 4 KHz refresh rate.
DO NOT INSTALL DIMMS THAT DO NOT SUPPORT ERROR
CHECKING AND CORRECTING (ECC).
A DIMM can be installed one way only. Be sure to match the two key
slots on the DIMM with the tab on the DIMM socket. Push the DIMM
down into the DIMM socket, ensuring that it is fully inserted and
properly seated.
When upgrading, do not exceed 1 GB total. Upgrades exceeding
1 GB will cause the system to halt.

Installing DIMM Modules

IMPORTANT: Prior to installing additional DIMMs, read "Important
Guidelines for DIMM Installation" in the previous section.
To install a memory module:
1. Turn off the workstation and disconnect the power cord from the
grounded AC outlet and the back of the workstation.
2. Remove the side access panel.
CAUTION: When handling a DIMM, be careful not to touch any of
the contacts. Doing so may damage the module.
CAUTION: Static electricity can damage the electronic
components of the workstation or optional boards. Before beginning
these procedures, ensure that you are discharged of static
electricity by briefly touching a grounded metal object. Refer to
Appendix B, "Electrostatic Discharge," for more information.
