SFP transceivers must be matched with the correct cable type as follows:
1000BASE-SX, 1000BASE-LX, 1000BASE-LH70 or 1000BASE-T:
■
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 79.
