Stacking Slots
The switch comes with two stacking slots. The slots are the last two SFP+
slots on the switches and are labeled “S1/27” and “S2/28” on the switch.
The slots have two functions. You can use them with the VCStack feature
to build a stack of switches, or you can disable the VCStack feature and
use them as additional networking slots.
The names of the slots depend on the status of the VCStack feature on the
switch. When VCStack is enabled, the management software refers to the
slots as “S1” and “S2”. When you disable VCStack to use the slots as
regular networking ports, the slots are referred to as slots 27 and 28. For
instructions on how to disable VCStack to use the switches as stand-alone
units, refer to “Disabling VCStack” on page 83.
