The SBM-GEM-X2C+ has four LEDs to display the stacking identifier. Due to the limited
space available for LEDs, the stacking identifier is displayed in binary form using these
four stacking LEDs.

NOTE: In a stack only one switch can be configured as master. The slave
switches will not allow you to configure anything except stacking disabled. To
login to slave switches, use a login name as "stackuser" and password as
"stack123".
Removing a stacked switch
To remove a switch from stacking follow the below recommended procedure.
1. Disconnect stacking cables.
2. Reboot the removed switch as a standalone switch.
3. Disable stacking. Execute the "no stack" command.
4. Reboot the switch again to operate as regular stand-alone switch.
NOTE: When a switch is moved from stacking to stand-alone mode, the saved
stacking configurations can not be loaded in stand-alone mode. When stacking
is disabled, the switch software renames the existing configuration file to avoid
automatic restoration of stacking configurations on a stand-alone switch.
