Environmental Requirements
5.07 Refer to Table 2.5, page 2-10 for a list of environmental requirements.
Electrostatic Discharge (ESD) Precautions
5.08 Many components in the shelf can be damaged by electrostatic discharge
(ESD). When a step instructs you to protect a Tellabs 7345 Switch or Tellabs 7325
Switch component from ESD, follow the precautions described here.
5.09 Observe all electrostatic discharge (ESD) practices, equipment handling
guidelines, and power precautions. Always use the personal ESD antistatic wrist
strap, plugging into one of the available ESD jacks available on the sides of the
shelf.
Fiber Optic Safety
5.10 Laser products are the subject of federal, state, and local regulations. This
product complies with Code of Federal Regulations (CFR), Title 21, Part 1040.10
and 1040.11, Performance Standards for Light-Emitting Products as defined by the
Department of Health and Human Services, which operates under the Food and
Drug Administration (FDA); and International Electrotechnical Committee (IEC)
60825-1-2 as a hazard level 1 laser product.
5.11 The power level of the visible and invisible laser radiation emitted from an
unconnected optical facility receive cable is not under Tellabs’ control and may be
dangerous. Therefore, to ensure safety, assume that it is dangerous to your
eyesight.
Laser Radiation Exposure
5.12 Although the laser transmitter power output levels from the Tellabs 7300
NEs are below those known to cause injury to the eye from, for example, accidental
exposure to the end of an optical cable, avoid direct exposure at close distances.
During normal operation, the laser transmitters emit invisible laser radiation or
collateral radiation.
Warning:
This product contains static-sensitive components and should be handled with
care. Failure to employ adequate antistatic measures can cause irreparable
damage to components. Except when working with power cables, handle this
product only when wearing a grounded wrist strap in a grounded work area. Do
not remove modules from the shelf or from their electrostatic discharge (ESD)
shielding bags until a step instructs you to do so. Failure to follow ESD
precautions may cause hardware damage.
