Stack Version Requirements
NOTE:Switches can set up a stack through stack card connection and service port connection based on stack port types. Service port connections are classified into ordinary and dedicated cable connections based on cable types.
Ordinary cable connection: Switches use optical cables, network cables, and high-speed cables to set up a stack.
Dedicated cable connection: Switches use dedicated stack cables to set up a stack. This connection mode is also called zero-configuration stacking.

- If you want to set up a mixed stack of S5720SV2-28P-LI-AC and other switch models, only a mixed stack of the S5720SV2-28P-LI-AC and S5720SV2-52P-LI-AC is supported.
- In a stack set up using electrical interfaces, when adding a new member switch or replacing a faulty member switch, to prevent a packet loop caused by a failure to add the new member in case of insufficient ACL resources, you are advised to configure the service ports used in both the new switch and the stack as stack ports before connecting the switch to the stack using cables.
- Since V200R011C10, S5720LI and S5720S-LI series switches 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.

S5720SI, S5720S-SI, and S5720I-SI 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.
- After a UCL group is created using the ucl-group command on S5720SI&S5720S-SI&S5720I-SI switches, a stack cannot be set up.
- S5720SI series switches are classified into S5720-P-SI and S5720-X-SI based on their uplink interface types.
- S5720S-SI series switches are classified into S5720S-P-SI and S5720S-X-SI based on their uplink interface types.
- MultiGE ports of an S5720-14X-PWH-SI-AC cannot be used as stack member ports.
- In V200R010 and later versions, any models of S5720I-SI, S5720SI and S5720S-SI can set up a stack. When different models need to set up a stack, they must use stack ports of the same type. That is, they either all use electrical ports on front panels or all use SFP+ or SFP optical ports. In V200R009 and earlier versions, S5720-14X-PWH-SI-AC cannot set up a stack with S5720S-SI or other S5720SI models. The S5720S-SI can set up a stack with all S5720SI models except S5720-14X-PWH-SI-AC.
- Since V200R010, two SFP+ optical ports of an S5720-14X-PWH-SI-AC can be used as stack member ports. If SFP+ optical ports of an S5720-14X-PWH-SI-AC have been configured as stack member ports but the switch needs to be downgraded to V200R009 or an earlier version, delete the stack member port configuration of SFP+ optical ports before the downgrade. If this configuration is not deleted before the downgrade, a stack that cannot run normally will be set up after the downgrade. You need to disable the stacking function to delete the stack member port configuration of SFP+ optical ports.
- Among S5720I-SI series switches, the S5720I-6X-PWH-SI-AC and S5720I-10X-PWH-SI-AC do not support the stacking function.
- In a stack set up using electrical interfaces, when adding a new member switch or replacing a faulty member switch, to prevent a packet loop caused by a failure to add the new member in case of insufficient ACL resources, you are advised to configure the service ports used in both the new switch and the stack as stack ports before connecting the switch to the stack using cables.
- Since V200R011C10, S5720SI and S5720S-SI series switches can set up stacks in service port stacking mode using dedicated stack cables. S5720I-SI 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.

S5730SI Stack Card 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.
- Stack card stacking and service port stacking (including ordinary cable stacking and dedicated stack cable stacking) cannot be used together. If service port configurations are correct, service port stacking is preferred over stack card stacking. If stack card stacking has been used to set up a stack, to use service port stacking to set up the stack, you need to restart the stack to make service port stacking takes effect after configuring service port stacking.
- 40GE ports on the ES5D21VST000 stack card cannot be used together with 40GE ports on the ES5D21Q04Q01 card to set up a stack.
- The number of stacked switches is recommended to be 2 to 9.
