40-Gigabit Ethernet Modules

Table 2-64	WS-X6904-40G Ethernet Module Features
Feature		Description
Ports per module		• 4 ports—four 40-Gigabit CFP optics modules (ports 1 through 4)
		• 16 ports—four 10-Gigabit FourX adapters (ports 5 through 20)
		Note Each of the four optics bays on the module front panel can
			accept either one CFP transceiver module (one 40-Gigabit port)
			or a FourX converter and up to four SFP+ transceivers (four
			10-Gigabit ports). The module can also support a mix of both
			40-Gigabit CFP optics modules and 10-Gigabit SFP+
			transceivers (two 40-Gigabit ports and 16 10-Gigabit ports).
Port connector type		• MPO/MTP connector for the 40-Gigabit CFP transceiver module.
		• LC connector for the 10- Gigabit SFP+ transceiver.
Cabling distance		Dependent on the type of transceiver installed. See the transceiver data
		sheets or the transceiver installation notes for specific information on
		cabling distances with the each transceiver type.
Maximum frame size		Up to 9216 bytes
Supervisor engine support		Supervisor Engine 2T-10GE only
Software support		15.0(1)SY1 or higher
Queues per port		• 40-Gigabit Ethernet ports:
		–	Tx—1p7q4t
		–	Rx—1p7q4t
		• 10-Gigabit Ethernet ports:
		–	Tx—1p7q4t
		–	Rx—8q4t
Chassis/slot restrictions		• Not supported in non E-series Catalyst 6500 switches
		• Supported in a WS-C6503-E chassis with a hardware revision 1.3
		or higher
		• Requires that modules be installed in adjacent chassis slots or, if
		either adjacent slot is unused, you must install a switching-module
		filler plate (Cisco part numbers WS-X6K-SLOT-CVR-E or
		SLOTBLANK-09) rather than a blank slot cover
		(WS-X6K-SLOT-CVR) to maintain an adequate air flow through
		the chassis.
