Installing Memory Expansion Cards

Standard Memory There are three ECC-compatible slots for 72-bit DIMM memory expansion
submodules on the mother board. The current memory configuration is 64
MB. You can extend it up to a maximum of 384 MB. The memory comes
supplied with EDO RAM submodules.
Only one submodule must be fitted. You can fit a combination of EDO and
SDRAM submodules.
If ECC submodules are fitted in combination with non-ECC submodules, the
memory works without ECC backups or correction.
You will find the order numbers for the memory expansion cards in the
Product Information Bulletin.
Caution
!
Risk of damage!
The electronic components on the printed circuit boards are highly sensitive
to electrostatic discharge. When handling the boards or cards, you must
follow the guidelines for electrostatically sensitive components (ESD
guidelines at the end of this manual).
