Adding Memory
Note
:
Proper anti-static
procedures are required when handling the system board.
To add memory,
slide the system board out of the unit. You can now access the two
memory sockets, note that the order in which the memory is populated does not matter.
The J2 485 supports up to 16GB of memory in two sockets. Memory type is 240 DIMM
DDR3 1066/1333.

Changing the Processor
To change the processor, be sure to
first start by working in an anti-static workplace
with proper
grounding
. Remove the systems board from the system, now remove the
black plastic fan duct.
Loosen the four spring-loaded screws that secure the processor heat sink by turning each
screw about two turns at a time so that the pressure is removed from the socket evenly.
Once the screws are free you will now be able to remove the heat sink. It will stick
because of the heat sink compound, so take care to move it gently from side to side until
it comes off. Set the heat sink aside, top side down.
You can now remove the processor from the socket. Push the locking lever down, push
out from the locking tab, and move it up (
as shown?
). Now carefully lift the cover up and
you can remove the processor. **
Be sure only to touch the edges of the processor and
do not
touch the processor pads of the socket pins. These socket pins are very easy
to bend and damage to the socket is not covered by J2 warranty.**
