1000BASE-SX, 1000BASE-LX, 1000BASE-LH70 or 1000BASE-T SFP 
transceivers must be matched with the correct cable type as follows:

■

1000BASE-SX SFP transceiver

 

Use this transceiver to connect Gigabit Ethernet SFP ports on the 
Switch directly to a multimode fiber-optic cable.

■

1000BASE-LX SFP transceiver

 

Use this transceiver to connect Gigabit Ethernet SFP ports on the 
Switch directly to a single-mode fiber-optic cable or to a multimode 
fiber using a conditional launch cable.

■

1000BASE-LH70 SFP transceiver

 

Use this transceiver to connect Gigabit Ethernet SFP ports on the 
Switch directly to a single-mode fiber-optic cable.

■

1000BASE-T SFP transceiver

 

This transceiver uses Category 5 copper cabling with RJ-45 connectors 
and supports segment lengths of up to 100 m (328 ft).

If the SFP transceiver is faulty, it will not operate within the Switch. See 
“Solving Hardware Problems” on page 65.
