This chapter describes the precautions that should be observed for the
following:
•
handling and working with DV-45 shelves
•
handling, storing, installing, and replacing DV-45 units
•
handling, splicing, and repairing optical fibers
DV-45 shelf
The following precaution must be taken when handling and working with a
DV-45 shelf (this includes the external DLT or VCE cabinet, the DV-45 shelf
that is mounted inside the cabinet, and DV-45 units).
Wear a skin-contact antistatic bracelet when handling and working
with a DV-45 shelf. This bracelet consists of an expandable wrist strap
and grounding cord; its function is to rapidly dissipate charges to
ground. Alternative personnel ground methods can be used; for
example, conductive carpeting, conductive shoes, or heel grounding
assemblies. An electrostatic discharge jack is located on the front of all
DV-45 shelves.
DV-45 units
Damage to units, particularly those that are sensitive to static electricity, may
occur at any time. DV-45 units that are sensitive to static electricity are shipped
in antistatic shipping bags and are marked with the following symbol:
Note:
All DV-45 units must be installed or extracted by using the unit
latches to ensure a secure mating with the backplane.
CAUTION
Electrostatic sensitive devices
Avoid touching any components on the printed circuit board.
Electrostatic sensitive devices can be damaged by electrostatic
discharge. Always ground yourself before handling a board.
