standby unit (standby master) to reset the standby. You cannot reset any other unit from the standby
unit.

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.
