LS/VS550 OWNER’S HANDBOOK 5/7
Upgrading the motherboard
Caution
Caution
Care must be taken in the purchase of upgrade parts to ensure both
compatibility with the system and the compliance with appropriate
approvals and certification, e.g., CE marking within Europe. Using
non-approved parts may invalidate your warranty and system approvals.
The only tool required to complete the installation of the upgrades
is a small cross-head screwdriver.
Read all the instructions through carefully before starting. The tasks
are not difficult, but if you do not feel confident about the work
involved, you may wish to have your supplier or service organisation
complete it for you.
Warning
Warning
Never carry out any work inside the computer with AC power applied.
Turn off the computer and unplug all power cords before starting work.
Adding more memory
Memory can be fitted in three vertical DIMM sockets which must
be populated with gold contact, 3.3V, 72-bit unbuffered EDO type
DIMMs having 60 ns timing.
The three DIMM slots accept DIMMs of 16, 32 and 64 Mbytes
in any combination, to the maximum of 192 Mbytes.
Fitting and removing DIMMs
Note the indents along the connector edge, they prevent the
DIMM from fitting into the socket the wrong way round.
