Warning: These switches use lasers to transmit signals over fiber optic
cable. The lasers are compliant with the requirements of a
Class 1 Laser Product and are inherently eye safe in normal
operation. However, you should never look directly at a
transmit port when it is powered on.
Note: When selecting a fiber device, considering safety, please make sure
that it can function at a temperature that is not less than the
recommended maximum operational temperature of the product.
You must also use an approved Laser Class 1 SFP transceiver.
Hinweis: Bei der Wahl eines Glasfasertransceivers muß für die
Beurteilung der Gesamtsicherheit beachtet werden, das die
maximale Umgebungstemperatur des Transceivers für den
Betrieb nicht niedriger ist als die für dieses Produkts. Der
Glasfasertransceiver muß auch ein überprüftes Gerät der Laser
Klasse 1 sein.
1. Remove and keep the port’s protective cover. When not connected to
a fiber cable, the cover should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable
plugs by wiping them gently with a clean tissue or cotton ball
moistened with a little ethanol. Dirty fiber terminators on fiber cables
will impair the quality of the light transmitted through the cable and
lead to degraded performance on the port.
3. Connect one end of the cable to the LC port on the switch and the
other end to the LC port on the other device. Since LC connectors are
keyed, the cable can be attached in only one orientation.
