SIMM UPGRADE

PowerMate Ve ETC Series system configurations come with 16 MB of main system
memory. Four sockets on the system board support up to 128 MB of high-speed memory
using the following industry-standard, tin-plated, single in-line memory modules (SIMMs):
T
1-MB by 32- or 36-bit (4-MB stick)
T
2-MB by 32- or 36-bit (8-MB stick)
T
4-MB by 32- or 36-bit (16-MB stick)
T
8-MB by 32- or 36-bit (32-MB stick).
The system board can use 64-MB SIMMs (16-MB by 32- or 36-bit), but these SIMMs are
not supported by NECCSD for the PowerMate Ve ETC Series.

Performing Memory Upgrades

Upgrade system memory as follows:
T
locate memory sockets on system board
T
check installed system memory
T
install SIMMs.

Locating SIMM Sockets.

Remove the system unit cover and locate the six SIMM sockets on the system board (see
Section 3 of the PowerMate Ve Series Service and Reference Manual).
If any cables block access to the SIMM sockets, label and disconnect them. If any boards
block access to the sockets, remove them.

Checking System Memory

Use Table 1-2 to check the memory installed in the system and determine the SIMM
configuration needed to increase memory.
NOTE: You may install 60-ns, parity or
nonparity, extended data output (EDO) SIMMs
into the SIMM sockets.
CAUTION: To avoid corrosion between
different metals, only use tin-plated SIMM sticks.
