Making Network Connections

Figure 4-3 Making Connections to SFP Transceivers

4. As a connection is made, check the Link LED on the switch corresponding to

the port to be sure that the connection is valid.

The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at

1 Gbps full duplex. The maximum length for fiber optic cable operating at Gigabit

speed will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet

Collision Domain” on page 4-6.

10 Gbps Fiber Optic Connections

An optional 10 Gigabit 10GBASE-LR transceiver (Xenpak or XFP) can be used for a

backbone connection between switches.

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with

an LC connector at both ends.

Warning: 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.

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 or SC port on the other device. Since LC connectors are keyed, the

cable can be attached in only one orientation.
