S5731-S and S5731S-S Service Port Stacking Support

Enterprise

Worldwide

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.
Combo ports cannot function as stack member ports.
For stacking-supported service ports, some of them can be used as stack ports, whereas some can be used as ordinary service ports.
S5731-S and S5731S-S series switches of all versions can set up stacks in service port stacking mode using dedicated stack cables.
The number of stacked switches is recommended to be 2 to 9. In addition, when using iMaster NCE-Campus to manage and maintain a stack, ensure that the stack has no more than four member switches.

Table 3-25 Service port stacking support

Device Series	Port Supporting Stacking	Stack Cable	Rate of a Single Port	Remarks
S5731-S and S5731S-S	Four 10GE SFP+ optical ports	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 S5731-S series can set up a stack. Any models of the S5731S-S series can set up a stack. A stack cannot be set up between the S5731-S and S5731S-S. A switch supports a maximum of two logical stack ports, and each logical stack port supports a maximum of eight stack member ports. Each switch can use a maximum of eight service ports as stack member ports.
