Force10 Networks Switch IO Module CC-C-BLNK-LC User Manual

Hardware Overview

The MXL 10/40GbE Switch provides two native 40-Gigabit Ethernet fixed ports 

on the base module for uplink connections. You can use these ports with 4x10G 

breakout cables to operate as 10GbE uplink ports. 
In addition, you can configure the native 40GbE ports as stacking ports. You 

can connect up to six MXL 10/40GbE Switches (in the same or different 

chassis) in a single stack. For more information, refer to "Assembling a Switch 

TM

The MXL 10/40GbE Switch (Figure 1-2) provides 10/40GbE external 

connectivity by using the following FlexIO plug-in modules in the two 

expansion slots:

• 4-Port 10-Gigabit Ethernet module using SFP+ optics (SR or LR) or 

direct-attach cables (1m, 3m, or 5m DAC) 

• 4-Port 10GBASE-T module using RJ-45 connector (copper) cables 

 

The 10Mb speed is not supported on the 4-Port 10GBASE-T module. 

Only 100Mb, 1GbE, and 10GbE speeds are supported. 

• 2-Port 40-Gigabit Ethernet quad form-factor pluggable plus (QSFP+) 

module which you can use for 40GbE connections or 10GbE small form-

factor pluggable plus (SFP+) connections using 4x10G breakout cables. 
By default, the 40GbE ports on a 2-Port 40GbE QSFP+ module come up 

in 4x10GbE (quad) mode as eight 10GbE ports. To change a port from 

4x10GbE to 40GbE mode of operation, enter the 

portmode quad command.

portmode quad

stack-unit unit-number: Enter the number of the stack unit to be 

reset. Range: 0-5. To display the stack-unit number, enter the show 

system brief command. 
port port-number: Enter the port number of the 40GbE QSFP+ port 

to be split. Valid values for slot 0: 41 or 45; for slot 1: 49 or 53 (see 

"Port Numbering" on page 9).
portmode quad: Identifies the port as a split 10GbE SFP+ port.
