S6730S-H Service Port Stacking Support

For the cables that can be used as stack cables, see "Cables" in the Hardware Description. Using other cables may cause exceptions in the stack system, for example, frequent error-down events on stack ports.
For stacking-supported service ports, some of them can be used as stack ports, whereas some can be used as ordinary service ports.
All versions of S6730S-H series switches support service port stacking using dedicated stack cables.
The number of stacked switches is recommended to be 2 to 9.

Device Series	Port Supporting Stacking	Stack Cable	Rate of a Single Port	Remarks
S6730S-H	10GE ports on the front panel	1 m, 3 m, and 5 m SFP+ passive high-speed copper cables 10 m SFP+ active high-speed copper cables 3 m and 10 m AOC cables 10GE SFP+ optical module and optical fiber 0.5 m and 1.5 m SFP+ dedicated stack cables	10 Gbit/s	Any models of the S6730S-H series can set up a stack. The S6730S-H cannot set up a stack with other switches. Two types of ports on a switch can be both configured as stack ports, and each logical stack port can contain only one type of ports. When using 10GE ports as stack ports, a switch supports a maximum of two logical stack ports, and each logical stack port supports at least one stack member port and at most eight stack member ports. A switch supports a maximum of 16 stack member ports. 40GE ports do not support the stacking function after they are split into 10GE ports. When using 40GE ports as stack ports, a switch supports a maximum of two logical stack ports, and each logical stack port supports at least one stack member port and at most six stack member ports. Each switch can use a maximum of six service ports as stack member ports. When using 100GE ports as stack ports, a switch supports a maximum of two logical stack ports, and each logical stack port supports at least one stack member port and at most six stack member ports. Each switch can use a maximum of six service ports as stack member ports. Only the last 16 10GE ports on the front panel can be used to set up a stack using dedicated stack cables.
