Reviewing Indicators to Check Whether a Stack Has Been Established

Context

After you complete configurations for establishing a stack, you can review indicators on the switch panels to check whether the stack has been established successfully.

Procedure

Press the mode switching button on any member switch to set the mode status indicator to work in stack mode. A switch has a STCK indicator, which indicates the stack mode status. After you press the MODE button, the indicator is steady green or blinking and off in 45 seconds, indicating that the switch has entered the stack mode.

The S5732-H, S6730-S, S6730S-S, S6720-HI, S6730S-H, and S6730-H do not have the mode switching button, have an independent stack master/slave indicator to show the MST indicator. If the indicator is off, the switch is not a stack master. If the indicator is steady green, the switch is a stack master or standalone switch.

If the mode status indicators on all the member switches change to the stack mode, the stack has been established successfully. You can determine the stack IDs of the master switch and member switches by viewing the mode status indicator and service port indicators. For details, see Table 1.
If the mode status indicators on some member switches do not change to the stack mode, the stack has not been established.

**Table 1** Service port indicators in STACK mode
Color	Status and Meaning
Off	This indicator does not indicate the stack ID of a stack member.
Green	If the indicator of a service port is blinking green, the switch where this service port is located is the master switch, and the number of this service port is the stack ID of this switch. If the first to nine service ports indicators of the switch are blinking green, this switch is the master switch, and its stack ID is 0. If the indicator of a service port is steady green, the switch where this service port is located is not the master switch, and the number of this service port is the stack ID of this switch. If the first to nine service ports indicators of the switch are steady green, this switch is not the master switch, and its stack ID is 0.
