You can connect two units with two or more stacking cables in case of a stacking port or cable failure. Removal of only one of
the cables does not trigger a reset.
Enabling Mixed-mode Stacking
On the S4048-ON and S4048T-ON switches, mixed-mode stacking is disabled by default.
To enable mixed-mode stacking on the S4048T-ON or S4048–ON, perform the following steps:
1. In configuration mode, enter the mixed-mode-stacking enable command:
mixed-mode-stacking enable
The following message appears prompting you to confirm the configuration:
Enabling mixed-mode-stacking requires configuration save and reload to operate in
compatible with S4048-ON.
Do you want to reload? Proceed[confirm yes/no]:
2. Enter yes at this prompt and press the return key.
The following message appears prompting you to save the configuration:
System configuration has been modified. Save? [yes/no]:
3. Enter yes again and press the return key.
Important Points to Remember
● You can stack up to six systems.
● You cannot stack one system with other system types.
● You cannot enable stacking and virtual link trunking (VLT) simultaneously on the device. To convert a stacked unit to VLT,
see Reconfiguring Stacked Switches as VLT.
● Data ports are configured as stacking ports in predefined groups of four 10G ports called stack-groups.
● When using the 40G ports, you can configure a single port as a stack port; each 40G port is a stack-group.
● All the ports in a stack-group are placed in stacking mode. Unused ports in that group cannot be used as data ports.
● Stacking on the device is accomplished through front-end user ports on the chassis.
● All stack units must have the same version of Dell EMC Networking OS.
