Memory Configuration Rules
The following configuration guidelines apply to all HP 3000 9X8 and HP 9000 800 Ex5 Class
systems.
1. Memory SIMMs MUST be installed in pairs.
2. Each memory SIMM installed in a slot pair must be the same size (e.g., 8MB and 8MB,
32MB and 32MB, or 64MB and 64MB).
3. The slots should be loaded starting with slot 3 (A and B) then slots 2 through 0
sequentially. This is due to the angle the SIMMs are inserted into the connectors during
installation.
Perform the following steps to add memory SIMMs to the computer:
1.
Perform a system shut down.
2. Press the ON /OFF switch to remove DC power from the system.
3. Disconnect the power cord from the wall outlet to remove AC power. If the computer is
connected to a UPS, put the UPS
Output
switch in the OFF
(0)
position, then remove
the line cord from the computer.
4. Loosen the two captive mounting screws on the Memory /CPU cover plate and remove the
cover plate.
5. Loosen the two captive mounting screws on the CPU card and remove the CPU card.
