Warnings and Notes
Danger: Invisible laser radiation can be emitted from the aperture ports of an optical module
when no cable is connected. Avoid exposure and do not stare into open apertures.
Warning:
• Do not install equipment that appears to be damaged.
• Impedance panels are required in all empty slots to prevent excess dust accumulation
and to help control airflow and electromagnetic interference. Impedance panels do not
have board components or connector pins.
• Electrostatic discharge (ESD) damage can occur if components are mishandled.
Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap
to the grounding plug on the front of the chassis.
• Always place components on an antistatic surface.
