3-10 Option Installation
SIMM MEMORY UPGRADE
SIMM sticks are installed into SIMM sockets on the system board. The system board has
four SIMM sockets and supports up to 128 MB of high-speed memory. The system
supports the following 32-bit (non-parity) SIMMs:
n
1-MB by 32-bit (4-MB stick)
n
2-MB by 32-bit (8-MB stick)
n
4-MB by 32-bit (16-MB stick)
n
8-MB by 32-bit (32-MB stick).
NOTE:
All the systems ship with 60-ns EDO
SIMM sticks.
CAUTION:
To avoid corrosion between
different metals, only use tin-plated SIMM sticks.
Checking System Memory
Use the following procedure to:
n
check the memory installed in the system
n
determine the SIMM configuration needed to increase memory
n
locate the sockets for SIMM installation.
1.
Locate the four SIMM sockets on the system board (see Figure Section 3-8).
2.
Identify the SIMM sockets by socket number (see Figure Section 3-9).
If any cables block access to the SIMM sockets, label and disconnect them. If any
boards block access to the sockets, remove them.
3.
Use Table Section 3-1 to determine the SIMM configuration needed to upgrade
the memory and to identify the sockets for SIMM installation.
