1000Base-SX Fiber Ports
The 1000Base-SX fiber ports use SC connectors. Figure 2-4 shows an SC
fiber connector being inserted into a fiber port on the VH-8G.
Figure 2-4. Inserting an SC Fiber Connector into a Fiber Port
The 1000Base-SX fiber SC ports support multi-mode 62.5/125µm fiber.
The fiber connectors are configured as a receive (RX) / transmit (TX) pair.
1. Remove and keep the SC 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. 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 optic
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 SC port on the switch and the
other end to the SC port on the other device. Since SC connectors
are keyed, the cable can be attached in only one orientation.
4. As a connection is made, check the green Link LED on the switch
corresponding to the port to be sure that the connection is valid.
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.
Before connecting cables, you may want to first configure
the Spanning Tree Protocol and trunk links to avoid network
loops. Refer to the Management Guide for more information.
