Ruijie RG-S2900G-E Series - Configuring a Stack; Identifying Stack Member Device According to the Device Number

Configuration Guide Stack Management
In the stack environment, if link loss of the stack cable is detected, the management of the
stack will fail, and the system will send a log to the user:
STACKMODULE-LINKSTATUS-CHANGED: Link loss is detected in the stack loop.
Device [2] loss has been detected, system will reset.
If link recovery of the stack cable is detected within 3 seconds, the stack environment will
recover, and the system will send a log to the user:
STACKMODULE-LINKSTATUS-CHANGED: Link recover is detected in the stack loop.
If link loss lasts for more than 3 seconds, the stack cannot work normally, and the stack system
will restart to create another stack.
When the network traffic is excessively heavy, the management of the stack will fail. In this
case, you do not need to restart the switch. When the network traffic decreases, the switches in
the stack environment will restore normal running.
The stack does not support hot plugging/unplugging, which means that you cannot insert,
remove or replace any member devices when the stack is running. Otherwise the stack system
will restart to create another stack. In a stably working stack environment, if any switch is
powered off and is re-powered on, all other switches in the stack will be automatically reset and
another election will be made to create a new stack.
Caution
When the stack is running, if you insert, remove or replace the member
devices, the stack will be reset and another election will be made to create a
new stack.

Identifying Stack Member Device According to the Device Number
The host in the stack system is elected according to device priorities. The one with the highest
priority value is the host. When two member devices have the same priority value, they are
elected according to their MAC addresses. The one with a smaller MAC address is the host.
After you configure the priority of a device, you must restart the device to put the setting into
effect.
After the stack is established, you can only execute out-band management by using the serial
port of the host. Therefore, you are recommended to first select a host before you establish a
stack, and then set its priority to a higher one in the standalone mode. As a result, you can
