Installing The Simm Modules - VESA 80486VESA User Manual

Installing The SIMM Modules

The 80486VESA system board can accommodate up to a
maximum of 32 megabytes of memory on board using 8 sockets
for the standard 30-pin SIMM memory modules. Two banks of
SIMM modules are available for use with 256KB x 9, lMB x 9 or
4MB x 9 - 80 nanosecond, fast page mode SIMM memory mod-
ules. Each bank contains four SIMM memory sockets. When
installing or removing the SIMM memory modules, extreme care
must be taken to avoid damage to the SIMM sockets. The
80486VESA system board can be configured for various memory
configurations from 1MB to 32MB. (Refer to Table 4, page 13, for
the memory configurations available).
To install a SIMM memory module, carefully follow the steps
below:
Step 1 Insert the SIMM module's "gold edge" connectors into the
socket at a 70-degree angle and guide the component side
of the SIMM module to face the edge of the board. The
module can only fit into the socket one way.
Step 2 Gently press the SIMM module toward the edge of the
board until it snaps into the socket in a vertical position.
The module should clip into the locking tabs at each end
of the socket. If the pegs do not fit into the holes, the
SIMM is probably not inserted fully into the socket.
To remove a SIMM memory module, carefully follow the steps
below:
Step Gently push the edge of the sockets to release the module.
1
Remove one side of the SIMM module first then the other
side, to prevent from breaking the socket. The module
should fall back at an angle; then it can be removed from
the socket.
