IBM 2104 Model DU3 - Manual (Page 13)

Electrostatic Discharge (ESD)
Attention:
When you handle field-replaceable units (FRUs) and other computer parts,
take these precautions to avoid static damage:
v Limit your movement. Movement can cause static electricity to build up
around you.
v Always touch computer parts carefully. Hold adapters and
memory-modules by their edges. Never touch any exposed circuits.
v Prevent people who are not correctly grounded from touching computer
parts.
v Before you install a new part, touch the static-protective package that
contains the part against an unpainted metal part of the 2104 or using
system for at least two seconds. This action reduces static electricity in the
package and in your body.
v Remove the part from its package and, if possible, install it directly into the
2104 without putting the part down. If you need to put the part down, first
place the static-protective package that contained the part onto a smooth,
level surface, then place the part onto the package. Do not place the part
onto any metal surface.
