OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.10(0.1) Introduced on the S4048T-ON and S4048–ON.
Usage Information
• To form a mixed-mode stack, use only the 40G ports between the range 49 to 54.
• You cannot form a mixed-mode stack using the 10G ports. Because, the 10G ports on the S4048T are copper
ports; where as, the 10G ports on the S4048-ON are SFP ports.
• It is mandatory to enable mixed-mode stacking on the S4048-ON and S4048T-ON switches before joining a
mixed-mode stack.
• Stack election is based on the priority or the MAC address of the stack units as in homogenous stacking. The
stack-unit with the highest priority or MAC address is chosen as the master.
• TDR is a feature that is supported only on the S4048T-ON but not on the S4048-ON. If TDR is congured on
the S4048T-ON, then mixed-mode stacking can be enabled only on the S4048T-ON switches.
• The hardware watchdog command is enabled only when the S4048T-ON act as master. As a single image
runs on both the S4048T-ON as well as the S4048–ON, the hardware watchdog command is retained on
the S4048-ON also. However, this command remains ineective and does not perform any function when the
S4048-ON acts as master.
• When the S4048T-ON is the master and mixed-mode stacking is disabled, the S4048-ON remains in the card
problem state due to type mismatch.
• When the S4048-ON is the master and mixed-mode stacking is disabled, the S4048T-ON remains in the card
problem state due to type mismatch.
