Rockwell Automation 6155 Industrial Computer Installation - Manual (Page 16)

Publication 6155-IN001C-EN-P
4-2 Bulletin 6155 Industrial Computer
Internal 6155 Computer components may be damaged by Electrostatic
Discharge (ESD). Make sure you wear a grounding strap whenever
handling circuit boards, memory modules or other internal components.
Also observe the following precautions:
• Always handle the memory cards by the ends not by the memory
module contacts.
• Store memory in a sealed anti-static bag when it is not installed.
• Never install or remove memory with the power turned on.
This section gives instructions on how to change an installed memory
module in the 6155 Computer processor board.
To add or remove memory:
1. Disconnect power from the 6155 Computer.
2. Remove the top cover of the 6155 Computer. Refer to procedures in
Chapter 2 for details on how to remove the top access cover.
3. Remove the existing DIMM module from the CPU card by pressing
down on the retaining latch. The DIMM module is located at the
top of the CPU card, just below the top access cover.
4. To install a new DIMM, hold the module only by the edges as you
remove it from its anti-static package.
5. Position the DIMM so that the small notches in the bottom edge of
the DIMM align with the notches in the DIMM socket on the CPU
card. The retaining latch should be fully disengaged when
attempting to install a DIMM.
6. Press down firmly and uniformly on the DIMM to seat it in the
socket. The latch should engage in the DIMM locking slot to secure
the part in place.
7. Reinstall the top access cover.
ATTENTION: Wear a wrist strap (well grounded) and
perform work in a static-safe environment. Electrostatic
discharge can damage the 6155 Computer and
components.
Adding/Removing
Memory Modules
ATTENTION: Disconnect all power from the 6155
Computer before adding/removing components. Failure
to disconnect power could result in severe electrical
shock or damage to the 6155 Computer.
