ESP630 contains two buttons to control stacking. When pressed, the Stack/Uplink button makes
the Switch operate in standalone mode, allowing the ports 27 and 28 to be used as normal Ethernet
ports instead of stacking ports. When stacking mode is selected, the Slave/Master button selects one
switch in the Stack to operate as the master. The entire stack will be managed by this unit.
