Preventive Maintenance

Preventive Maintenance

The TimeProvider shelf requires minimal preventive maintenance. Take care to
ensure the unit is not exposed to hazards such as direct sunlight, open windows,
water, or extreme heat. See
on page 48, for electromagnetic compatibility conditions that may cause damage.
Caution: To avoid electromagnetic discharge damage to the
circuitry, never attempt to vacuum the TimeProvider main shelf or
expansion shelf.
Caution: To avoid damage, under no circumstances should the
interior chassis of the TimeProvider be allowed to come in contact
with water.
Table 6-1 lists preventive maintenance measures to be performed periodically. Do
not disassemble components just for the purpose of inspection.

ESD Considerations

Maintenance personnel should wear ESD wrist straps when installing or working on
all TimeProvider equipment and cards. Plug the user-supplied wrist strap into the
TimeProvider shelf. Place IMC and IOC cards as well as the Input and Output
panels into static-free bags when not in use.
