Exchanging the Memory on the System Card
The 2216 comes with a minimum of 64 MB (one dual inline memory module [DIMM]). There are slots for
two DIMMs on the system card.
This procedure can be used for removing faulty DIMM modules or to install memory upgrades to your
2216.
1
Identify the faulty memory module. DIMM socket A is positioned closest to the edge of the system
card.
2
Remove one or both of the DIMMs by pulling down the lever to the left. (Use your thumbnail or a
small non-metallic device to gently move the spring latch away from the end of the DIMM.) The
DIMM will automatically be pushed partially out of the slot.
3
Gently slide the DIMM module out of its connector socket.
4
If you are installing new memory DIMMs, continue with the following procedure: (If you are replacing
DIMMs that you previously removed, go to step 6 on page 2-12.)
a
Remove the DIMM, in its antistatic bag, from its shipping container.
Attention: Electrostatic discharge (ESD) can damage the static-sensitive devices on circuit
boards. To avoid this kind of damage, use the following precautions:
¹
Do not remove the DIMM until you are ready to insert it into the 2216.
¹
Use correct grounding techniques when inspecting and installing the DIMM. Use a foot
strap or grounding mat, or wear a grounded static discharge wrist strap, or touch a
grounded rack or other source of ground before you handle the DIMM.
b
Remove the DIMM from the antistatic bag. Inspect it for damage. Always handle the DIMM
by the ends (preferably grasp it between the middle finger and thumb; do not touch the
components). If the DIMM appears to be damaged, return it to the antistatic bag and contact
the supplier.
