The 2GB memory option (256MB DIMMS) require that the system flash
PROM software be 3.2.24 or compatible versions before installing
memory modules.
Currently, for Solaris 2.5.1 operating environments, configurations are
limited to a maximum total memory of 56GB, configurations that
exceed 56GB for this version are not supported. Solaris 2.6 operating
environments, together with patch 105181-19, support a maximum
configuration of 60GB. There is no limitation for systems running
Solaris 7 or 8 operating environments (maximum achievable
configuration is 60GB).
Do not mix different densities (8 or 32 or 128 or 256 Mbytes) in a bank.
To install the Solaris 2.6 operating environment, use the "Operating
Environment Installation CD (part number 704-7076-10) February 2000"
that comes with your system (not required for installing Solaris 2.5.1,
Solaris 7 or Solaris 8 operating environments).

Caution – Use a padded ESD mat to prevent breakage of parts
mounted on the bottom of the board. Use a grounding wrist
strap to prevent static damage.

If your system supports the hot-plug feature, a board is in low-power
mode and ready for removal if one of the following is true:

1. Open the DIMM socket by pressing down on the ejector levers at
both ends of the socket.

3. Pull the ends of both extraction levers toward you, then pull the
board out of the card cage.
Do not let the components on the board catch on any surrounding
surfaces as you pull the board.
3. Push the DIMM firmly down into the socket.
Caution – The heatsinks on the board may be hot. Handle with

2. Align the two notches at the bottom of the DIMM with the two tabs

Suggestions for Maximum Performance
If there is more than one CPU/Memory board, install one bank of
DIMMs on each board first. Then install the second bank on any board.
It does not matter whether the first bank is bank 0 or bank 1.
Begin with the largest density banks first (256 Mbyte DIMMs), continue
with medium density banks (32 or 128 Mbyte DIMMs), and finish with
the smallest density banks (8 Mbyte DIMMs). It may be necessary to
move some banks to meet this guideline.
If there are remaining banks, fill the second banks on the boards in the
same order as the first banks.
Bank 0
1. If the board is in low-power mode, skip this step and go to Step 2.
If the board is not in low-power mode, halt the system and turn off
power before proceeding.
For Solaris 2.5.1 operating environments the /usr/platform/sun4u/
sbin/prtdiag command displays erroneous memory capacity
information. Use software patch 104595-09 (available at: http:// to correct this problem.

4. Place the board on a padded ESD mat to prevent breakage of parts

Installing DIMMs
Install a set of DIMMS as a complete bank of eight DIMMS. There are two
banks, interleaved as shown in the following figure. The socket numbers
(Jxx00 and Jxx01) are marked on the board.
4. Lock the DIMM in place by pushing both ejector levers into the
upright position.
Installing the CPU/Memory Board
1. If you are installing a new board, refer to the Sun Enterprise server
system reference manual that came with your system for rules for
selecting a board slot.
2. Open the extraction levers by pulling the ends of both levers toward
3. Insert the board in the card cage slot.
For a 4-slot or 5-slot card cage, orient the board with the component
side to the right.
For a 16-slot or 8-slot card cage (diagram follows):
Front slot installation, orient the board with the component side down.
Rear slot installation, orient the board with the component side up.
4. Push the board into the card cage, then simultaneously press both
extraction levers to seat the board on the centerplane.
6. Reboot the system now or schedule a later time to reboot when
system disruption will be minimized.
The system cannot use the new board until the system is rebooted.
7. If the system is running, look for a system message similar to the
following example.
This example is for a CPU/Memory board in slot 5:

Hold the board only by the edges. If a heatsink is
loose or broken, obtain a replacement board.

centerplane connectors.
Pushing both levers simultaneously avoids twisting the board and
