4.3 Preventing Damage to 
Removable Drives
Removable drives are fragile components that must be handled 
with care. To prevent damage to the computer, damage to a 
removable drive, or loss of information, observe the following 
precautions:
■Before removing or inserting a hard drive, shut down the 
computer. If you are unsure whether the computer is off or 
in hibernation, turn the computer on, and then shut it down 
through the...

4.4 Preventing Electrostatic Damage
Many electronic components are sensitive to electrostatic 
discharge (ESD). Circuitry design and structure determine the 
degree of sensitivity. Networks built into many integrated circuits 
provide some protection, but in many cases, the discharge 
contains enough power to alter device parameters or melt 
silicon junctions.

4.5 Packaging and Transporting 
Precautions
Use the following grounding precautions when packaging and 
transporting equipment:
■To avoid hand contact, transport products in static-safe 
containers, such as tubes, bags, or boxes.
■Protect all electrostatic-sensitive parts and assemblies with 
conductive or approved containers or packaging.
■Keep electrostatic-sensitive parts in their containers until 
the parts arrive at static-free...

4.6 Workstation Precautions
Use the following grounding precautions at workstations:
■Cover the workstation with approved static-shielding material 
(refer to 
Table 4-2, “Static-Shielding Materials”).

4.7 Grounding Equipment and 
Methods
Grounding equipment must include either a wrist strap or a 
foot strap at a grounded workstation.
■When seated, wear a wrist strap connected to a grounded 
system. Wrist straps are flexible straps with a minimum of 
one megohm ±10% resistance in the ground cords. To provide 
proper ground, wear a strap snugly against the skin at all times. 
On grounded mats with banana-plug connectors, use...
