Storing And Transporting Circuit Packs; Laser Radiation - Nortel SONET AccessNode Manual

To avoid static electrical damage when handling circuit packs, follow these
rules:
•
•
Protect optical connectors by covering them with clean dust caps.

Storing and transporting circuit packs

When storing and transporting circuit packs, follow these rules:

Laser radiation

AccessNode equipment and associated optical test sets use laser sources that
emit light energy into fiber cables. This energy is within the red (visible) and
infrared (invisible) regions of the electromagnetic spectrum.
Laser products are subject to federal and state or provincial regulations, and
local practices. Regulation 21 CFR 1040 of the U.S. Bureau of Radiological
Health requires manufacturers to certify each laser product as Class I, II, III,
or IV, depending upon the characteristics of the laser radiation emitted. In
terms of health and safety, Class I products present the least hazard (none at
all), while Class IV products present the greatest hazard.
Do not remove circuit packs from their antistatic packages unless you are
using antistatic protection, such as wearing an antistatic wrist strap. The
wrist strap is attached to a long cord, that must terminate at a good ground
source, so that static buildup is harmlessly discharged. Alternative
antistatic methods include conductive carpet, conductive shoes, or heel
grounders. Use the equipment recommended by your company.
Handle each circuit pack by the faceplate or stiffener. Do not touch
electrical connections, pins, or soldered surfaces.
Never transport, stack or store circuit packs without first replacing them in
their antistatic material and original shipping package. This avoids
physical damage and accumulation of dirt or dust on goldplated contacts.
Be careful not to damage any parts when inserting the circuit pack into its
packaging.
Avoid storage in areas where the relative humidity can exceed 95% and
where the temperature can exceed 70°C, because boards may warp or
corrode.
CAUTION
Risk of eye damage
At all times when handling optical fibers, follow the safety
procedures recommended by your company.
Read and follow the precautions below, to decrease the risk
of exposure to laser radiation.
