• 10-Gigabit Ethernet Configuration
– Catalyst 3750G-16TD switch—16 10/100/1000 Ethernet ports and 1 10-Gigabit Ethernet
XENPAK module slot
Note The 10-Gigabit Ethernet XENPAK modules are referred to as 10-Gigabit Ethernet module
ports in the software documentation.
• The switches support these SFP modules:
– 100BASE-FX multimode fiber (MMF)
– 1000BASE-BX
– 1000BASE-LX
– 1000BASE-SX
– 1000BASE-ZX
– 1000BASE-T
– Coarse wavelength-division multiplexing (CWDM)
Note When you install 1000BASE-T SFP modules in Catalyst 3750 switches, they can operate either
at 10, 100, or 1000 Mb/s in full-duplex mode or at 10 or 100 Mb/s in half-duplex mode.
• For a list of the XENPAK modules that the Catalyst 3750G-16TD switch supports, see Table B-2 on
page B-4.
• Configuration
– For 10/100 ports, autonegotiates the speed and duplex settings
– For 10/100/1000 ports, autonegotiates the speed and supports only full-duplex mode
