Memory Configuration
Each of the two 200-pin SODIMM sockets on the AMC131 is populated with DDR2 memory
that is configured to run at PC2-3200 speed with a 1.0GHz processor. The 1.33 GHz and
1.5
GHz options are populated with PC2-5300 DDR2 memory that is configured to run at
266 MHz and 300 MHz respectively. A single socket can support a 2GB module, but the total
memory loaded in the two sockets must not exceed 3GB.
Memory is not a field serviceable item. Return the module to PT for memory replacement. See
“Return Merchandise Authorization (RMA),” on page 19 for more information about returning
merchandise.
Figure 3-1 shows the memory addressing for the AMC131.

Working with the MiniSD Card
MiniSD card support is provided via a miniSD card socket located on the solder side of the
board. See
Figure 3-2, “Installing a MiniSD Card,” on page 36 for the socket location.
Removing a MiniSD Card
To remove the miniSD card from the socket:
1. Push in on the miniSD card to unlatch it. The miniSD card springs out about 1/4" from the socket
when it is properly unlatched.
2. Gently remove the miniSD card from the socket.
Installing a MiniSD Card
To install a miniSD card in the socket:
1. Orient the AMC131 and miniSD card as shown in Figure 3-2 , with the miniSD card label away from
the AMC131 PCB. Many miniSD cards have an arrow silkscreened onto their label side, as shown in
Figure 3-2 , indicating the end that should be inserted into the socket.
2. Insert the miniSD card into the socket until it clicks into place.
