Determine Which Accessories You Need

Use the guidelines described in this section when purchasing additional memory
and processors.

Memory

The upgrade kit comes with one memory board and one 256-MB DIMM.
WARNING
You cannot move the EDO DIMMs that came with the
LXr 8000 to the LXr 8500.
You can purchase additional memory following these guidelines:
l
DIMM sizes can be mixed per board, and can be placed in any DIMM
socket. There are no requirements to load the sockets in any specific
sequence.
For up to eight DIMMs, use one memory board.
For more than eight DIMMs, a second memory board must be installed to
maintain compliance with electromagnetic compatibility standards.
If you are using two memory boards, you can leave one board empty and
install up to 16 DIMMs on one board. Or, you can install DIMMs on both
boards.
l
If you install DIMMs on both boards, the two boards must be identically
configured with DIMMs. You may still mix DIMM sizes and place the
DIMMs in any order, but the same size DIMM must be placed in the same
socket position on both boards.
NOTE
If DIMMs of different sizes are installed in the same number
socket on the two boards, this is a "mismatched pair." If a
mismatch is detected during the start-up memory tests, both
mismatched DIMMs will be reconfigured to use the smaller of
the two sizes.
If you install DIMMs on both boards, you must install an equal number of
DIMMs on each board. The system will de-configure any unpaired
DIMMs.
