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 SC port on the switch and the other end to
the LC or 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 Link LED on the module to be sure that the
connection is valid.
The 10GBASE fiber optic ports operate at 10 Gbps full duplex. The maximum length
for fiber optic cable operating at 10Gbps speed will depend on the fiber type as listed
under “10 Gbps Ethernet Collision Domain” on page 4-6.
Connectivity Rules
When adding hubs (repeaters) to your network, please follow the connectivity rules
listed in the manuals for these products. However, note that because switches break
up the path for connected devices into separate collision domains, you should not
include the switch or connected cabling in your calculations for cascade length
involving other devices.
1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
