Caution: This switch uses 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 SFP 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.
Note: 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 LC port’s rubber cover. When not connected to a fiber
cable, the rubber cover should be replaced to protect the optics.
2. Check that the fiber terminators are clean. Yo u 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 por t .
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.

5. As a connection is made, check the Link LED on the switch corresponding to
the port to be sure that the connection is valid.
