S5700-HI and S5710-HI 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.
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.
The number of stacked switches is recommended to be 2 to 5.

**Table 1** Service port stacking support
Device Series	Port Supporting Stacking	Stack Cable	Rate of a Single Port	Remarks
S5700-HI	10GE ports on front cards: The S5700-HI supports ES5D00X2SA00 and ES5D00X4SA00 front cards, which support two and four 10GE SFP+ optical ports respectively.	1 m and 3 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	10 Gbit/s	Any models of the S5700-HI series can set up a stack. 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 four stack member ports. A switch supports a maximum of four stack member ports. After a front card is replaced by a card of a different type, the stack configurations become ineffective and need to be performed again.
S5710-HI	8*10GE ports on the front panel	3 m and 10 m AOC cables 10GE SFP+ optical module and optical fiber	10 Gbit/s	Any models of the S5710-HI series can set up a stack. 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 four stack member ports. Each switch can use a maximum of eight service ports as stack member ports.
