Upgrades WorkGroup Server 8550/132 Upgrade - 22
All of the part listed above, except for the DRAM DIMMs,
need to be removed from the original unit and installed in the
upgraded unit. Refer to the Take Apart chapter for the
product from which you are upgrading for instructions on
how to remove these parts. Refer to the Take Apart chapter
in the Power Macintosh 8500/WS 8550 manual to see
where the peripherals should be installed in the upgraded
unit.
Note:
The WS 8550 logic board in the upgrade kit does not
contain any DRAM. You must install 64 bit-wide, 168-pin
DRAM DIMMs. The DIMMs should be fast-paged mode, 70 ns
or faster. You can use 8, 16, 32, or 64 MB DIMMs, which
can be installed in any configuration. For the best
performance, however, the DIMMs should be installed in
pairs of the same size into paired slots. The slower 80 ns
SIMMs and DIMMs used in older Macintosh computers will
not work reliably in the WS 8550.
