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.
