Chapter 3: Pre-Installation Procedures
Antistatic Precautions
To prevent damage to components from static electricity:
 Do not handle circuit boards unless you are using the appropriate antistatic protection, such
as wrist straps, boot straps, boots, or a conductive mat. Wrist straps must have snug but
comfortable contact with your skin, and they must be connected to a grounding point on the
racks.
 Handle circuit boards by the faceplate, handles, or edges. Do not touch any integrated
circuits, connections, pins, or soldered surfaces.
Wrist-Strap Grounding Point
Each rack contains a wrist-strap grounding point in the bottom-left corner of the power distribution
panel (PDP). The grounding point is connected to the frame ground and provides antistatic
protection when technicians work with circuit cards.
NOTE: The racks must be grounded for the wrist-strap grounding point to be
effective.
Figure 3.1 Wrist-Strap Grounding Point
WARNING: Components in the base station are highly sensitive to electrostatic discharges
(ESD). Follow the procedures described below to prevent unseen damage from occurring.
