Concept Guide
If you use an active optical cable (AOC), you can convert the QSFP+ port to a 10 Gigabit SFP+ port or 1 Gigabit
SFP port. You can use the speed command to enable the required speed.

stack-unit portmode
Split a single 40G port into 4-10G ports on the switch.
Syntax
stack-unit stack-unit-number port number portmode quad
Parameters
stack-unit Enter the stack member unit identier of the stack member to reset. The range is 0 to 5.
NOTE: The switch commands accept Unit ID numbers from 0 to 5, though the
switch supports stacking up to three units only with the Dell Networking OS
version 8.3.7.1.
number Enter the port number of the 40G port to be split. Enter one of the following port
numbers for the switch: 48, 52, 56, or 60.
Defaults Disabled

Usage Information Splitting a 40G port into 4x10G port is supported on standalone and stacked units.
• You cannot use split ports as stack-link to stack a switch.
• The split ports switch unit cannot be a part of any stacked system.
• The unit number with the split ports must be the default (stack-unit 0).
• This set up can be veried using show system brief command. If the unit ID is dierent than 0, it must be
renumbered to 0 before ports are split by using the stackunit id renumber 0 command in EXEC mode.
The quad port must be in a default conguration before it can be split into 4x10G ports. The 40G port is lost in the
cong when the port is split, so be sure that the port is also removed from other L2/L3 feature congurations.
The system must be reloaded after issuing the CLI for the change to take eect.
