10.5 SIMMs
Caution – SIMMs consist of electronic components that are extremely sensitive to
static electricity. Ordinary amounts of static electricity from clothing or work
environment can destroy the SIMM.
Caution –
When removing a SIMM, an identical replacement is required. The
replacement SIMM must be inserted into the same socket as the removed SIMM.
Caution –
Each SIMM bank must contain at least two SIMMs of equal density (for
example, two 32Mbyte SIMMs) to function properly. Do not mix SIMM densities in
any bank.
Note – The system unit must have at least two identical SIMMs installed in paired
sockets of any SIMM bank. For best system performance, install four identical
SIMMs. TABLE 10-1 identifies SIMM installation locations.
