Operational Risks
Risk Details
Equipment Handling
l The weight of a fully equipped FSP 3000 C shelf varies
from moderate to heavy. When improperly handled, it may
fall causing personal injury and/or equipment damage.
Elevated Voltages
l There are particular points in the electrical equipment
(such as power supply, power connectors, backplane)
where elevated voltages are inevitably present. Under
normal circumstances, accidental contact with exposed
live parts is not possible. Consequently imminent danger
to you should not exist.
Elevated Operating
Temperatures
l Elevated operating temperatures may occur for some of
the circuit parts. Because such components are only
inside the equipment, they are not an imminent danger to
you or any other personnel. The fan tray modules (FTMs)
are present to cool the FSP 3000 C shelf and its
components.
Rotating Fan Blades
l Shelves with forced-air cooling have rotating fans on the
FTMs. These fans cannot accessed during normal
operation; therefore, the rotating fan blades are not
dangerous to service personnel.
l If the shelf has been opened for the purpose of
maintenance or service, rotating fan blades may become
dangerous. In this case, contact with rotating fan blades
can harm to your fingers. Always avoid touching rotating
fan blades.
l To minimize the risk of injury, the FTMs come with a
safety interlock that stops the rotating fan blades when
the unit is pulled out the shelf.
Laser Radiation
l During normal operating conditions, no human access to
hazardous laser radiation is possible (closed OFCS).
However, when an optical fiber cable is broken or an
optical fiber connector is unplugged or opened, someone
might be exposed to a level of optical radiation which is
above Hazard level 1M. For laser safety requirements,
APR/APSD procedures rapidly reduce the output power
not only on the main optical signal sources but also the
power on all pump-lasers employed, to a level below the
Hazard Level 1M, or shuts down these laser sources, if
necessary.
