Configure a switch as a slave switch in a stack of S series fixed switches

When more than two S series fixed switches set up a stack, one member switch is elected as the master switch, and one as the standby switch. The rest member switches function as slave switches, which are also called cold standby switches. A member switch function as a cold standby switch only when the stack elects other two member switches as the master and standby switches. You can configure using one of the following methods:
1. (Recommended) If you can control the switch startup, start the two switches to make them function as the master and standby switches and then start the switches that function as slave switches.
2. Configure a lower priority for a switch to reduce the possibility that the switch is elected as the master or standby switch.
3. If a stack has been set up, you can restart the master or standby switch. After the switch restarts, it rejoins the stack as a slave switch.
