Stacking Slots for VCStack
The front panel of the switch contains four SFP+ slots. Slots 27 and 28 can
be used to build a VCStack of up to four switches. The switches of a
VCStack act as a single virtual unit. They synchronize their actions so that
switching operations, like spanning tree protocols, virtual LANs, and static
port trunks, span across all the units and ports. The two main advantages
of stacks are:

You can manage multiple units simultaneously, which can simplify
network management.

You have more flexibility in how you configure some of the
features. For instance, a static port trunk on a stand-alone switch
has to consist of ports from the same switch. In contrast, a static
trunk on a stack may consist of ports from different switches in the
same stack.
Note
SFP+ slots 27 and 28 are initially configured as stacking slots for the
VCStack feature. To use the switch as a stand-alone unit, disable
the VCStack feature before using the slots. For instructions on how
to disable VCStack, see “Disabling VCStack” on page 83.
