S5732-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.
The number of stacked switches is recommended to be 2 to 9.
The minimum version required by the S5732-H24UM2CC and S5732-H48UM2CC is V200R019C10SPC500. In this case, when they set up a stack with a switch of another S5732-H model which acts as the master switch, the master switch must run V200R019C10SPC500 or a later version. Otherwise, the S5732-H24UM2CC and S5732-H48UM2CC cannot join the stack.

Device Series	Port Supporting Stacking	Stack Cable	Rate of a Single Port	Maximum of Logical Stack Ports	Maximum of Stack Member Ports in a Logical Stack Port	Remarks
S5732-H24S6Q S5732-H48S6Q	40GE ports	1 m, 3 m, and 5 m QSFP+ passive high-speed copper cables QSFP+ optical module and optical fiber (QSFP-40G-SR-BD optical modules can be used for stack since V200R019C10SPC500.) 10 m QSFP+ AOC cable	40Gbit/s	2	6	Any models of the S5732-H series can set up a stack. 40GE ports do not support the stacking function after they are split into 10GE ports.
S5732-H24UM2CC S5732-H48UM2CC	MultiGE ports	Category 6A or higher network cables (If Category 6 cables are used, ensure that the cables meet requirements of TSB-155.)	10Gbit/s	2	8	Any models of the S5732-H series can set up a stack. 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. 40GE ports do not support the stacking function after they are split into 10GE ports.
