Installing DRAM SIMM
The DA3000 RAID controller is equipped with two SIMM sockets. A mini-
mum of 8 MB of DRAM in one SIMM is required for it to operate.
SIMM Memory Installation Procedures:
1. The SIMM memory modules will fit in only one orientation as shown
because the plastic safety tab on one end of the SIMM socket requires the
notched end of the SIMM memory modules.
2. Press the memory module firmly into place starting from a 45-degree angle,
making sure that all the contacts are aligned with the socket.
3. With your fingertips, rock the memory module into a vertical position so
that it clicks into place. The plastic guides should go through the two
mounting holes and the clips should snap.
To release the memory module, push both clips outward and rock the
module out of the clips.
