Calling Technical Support
Repairs to the MAP/5 should be performed by an authorized representative. Field
service representatives can call for technical support to help solve problems. For
technical support call:
■
In the United States and Canada, contact the Technical Support Center
(TSC) at 1-800-562-8349
■
Outside of the United States and Canada, contact your local Lucent
Technologies representative or Lucent Technologies authorized distributor
Avoiding Electrostatic Discharge
Damage to Circuit Cards
The human body can collect thousands of volts of destructive static electricity
from ordinary activities, for example, walking on a rug, handling synthetic
materials, or wearing synthetic clothes. When this static electricity discharges
onto another surface at a different voltage potential, it is called electrostatic
discharge or ESD.
A person cannot feel ESD below approximately 3500 volts. However, only 30
volts are needed to damage ESD-sensitive electronic components.
Circuit cards and packaging materials that contain ESD-sensitive components
are often marked with a yellow and black warning symbol. Proper grounding
techniques prevent the discharge of damaging static electricity from your body
into these ESD-sensitive components during handling.
There is no quick method of testing for ESD damage. Components that are
damaged may simply fail after a brief period of normal operation.
To avoid damaging ESD-sensitive components, follow these rules:
■
Handle ESD-sensitive circuit cards only after you have attached a wrist
strap to the bare skin of your wrist. Attach the other end of the wrist strap
to a proper ground that terminates at the system ground, such as any
unpainted metallic chassis surface.
■
When working with circuit cards or components outside the MAP/5, place
them on an anti-static mat.
■
Handle a circuit card by the faceplate or side edges only (see Figure 2-1
and Figure 2-2). Do not touch components, leads, or connector areas
(gold finger pins).
!
CAUTION:
Ensure palm is not in contact with the wiring side of the circuit card.
