Prior to installing the DS2000-IFR please take a few moments to familiarize yourself with the following
common safety issues that may be encountered while servicing this unit.
2.2.1 Laser Warning
The four Ethernet Fiber Optic ports (optional) employ laser technology to transmit and receive
communications. In most cases, even when the DS2000-IFR is powered down, the technician must assume
there is still laser activity on the lines. Extreme caution must be exercised whenever handling the fiber lines.
Do not look into the fiber tip or direct the tip towards anyone else. Care must also be exercised when
disconnecting the fiber lines from the ports. Exposing the eye to the laser output could cause injury to the
eye or blindness. Whenever tasks call for the technician to handle the fiber lines, and be exposed to laser
output, a Laser Warning will appear in the text of this manual. The Laser Warning will appear as follows:
2.2.2 Fiber Optic Handling
If the optional Fiber Optic Ethernet ports are used, installing and maintaining the DS2000-IFR requires the
connection and disconnection of fiber optic cables. When disconnecting or connecting fiber optic cables to
the DS2000-IFR, follow these cleaning and handling recommendations.
2.2.2.1 Fiber Cleaning Conventions
Contamination from dust, dirt, oils from the hands and other sources can impede the transmission
and reception of optical signals through the optical fibers. When handling the optical connectors
and fiber cables, follow these precautions to minimize the contamination of the connectors and
ports:
• Cover optical connectors and ports with dust caps when they are not in use
• Do not touch fiber tips or the interior of optical ports when handling fiber cables
and connectors
• Clean fiber optic connectors as described “Cleaning Connectors” on page 4-3 prior
to making any optical connection
• Clean optical ports as described in“Cleaning Optical Ports” on page 4-4 if
contaminants or degraded performance are noted on the interface
LASER WARNING: Laser output can cause serious damage to the eye. The lasers
produced in the
DS2000-IFR and from the connected device produce light that is invisible to
the naked eye. It must be assumed at all times that the fiber optic cables and optical ports
are radiating light energy. When connecting or handling the fiber cables or connectors, it is
imperative that the technician avoid looking into the tip of the fiber or port.
