Note: A single pair of DIMMs is not supported on a feature #2884). In addition,
the #2884 can be ordered/installed, at any time, even with eight or fewer DIMMs
present. If a #2884 is installed, all DIMMs must be placed on it.
• Includes Base I/O backplane with CSP (CCIN 282D)
– #2457 Dedicated Domino processor: SStar 2-way (CCIN 25BD)
• Includes one 4MB L2 w/600MHz Oscillator, Smart Chip VPD Card
• Includes 16 DIMM memory positions via the base main storage expansion card
(CCIN 2884).
Main storage DIMMs must be plugged onto a main storage expansion card (both
base CCIN 2884 and feature #2884) and must be added in sets of four (quads) of
the same capacity and technology. There is an exception to allow a single set of
two main storage DIMMs if these are the only two on the system.
Note : A single pair of DIMMs is not allowed on these systems with a feature
#2884 either ordered or present. If DIMMs are added in addition to the initial two,
the initial two must be paired up to make a quad. Subsequent DIMMs must be
added in quads.
A feature #2884 may be ordered or installed at any time, even if the base main
storage expansion card is not full. For this processor, if a #2884 is ordered, a
#5157 Feature Power Supply must be either present or ordered. When a feature
#2884 is present (for a total of two memory expansion cards on the system),
manufacturing spreads the DIMMS across both memory expansion cards.
• Includes Base I/O backplane with CSP (CCIN 282D)
– #2458 Dedicated Domino processor: SStar 4-way (CCIN 25BE)
• Includes one 4 MB L2 w/600MHz Oscillator, Smart Chip VPD Card
• Includes 16 DIMM memory positions via the base main storage expansion card
(CCIN 2884).
Main storage DIMMs must be plugged onto a main storage expansion card (CCIN
2884 and #2884) and must be added in sets of four (quads) of the same capacity
and technology. There is an exception to allow a single set of two main storage
DIMMs if these are the only two on the system.
Note : A single pair of DIMMs is not allowed on these systems with a feature
#2884 ordered/present). If DIMMs are added in additional to the initial two, the
initial two must be paired up to make a quad. Subsequent DIMMs must be added
in quads.
A feature #2884 may be ordered or installed at any time, even if the base main
