Building a SummitStack Configuration

If you intend to use the SummitStack feature, read this section before installing the set of Summit family
switches that will be included in the SummitStack configuration. A stack consists of a group of up to
eight Summit switches that are connected together using stacking cables to form a connected ring, as
shown in Figure

Slot Numbers

Each switch (or node) in the stack is assigned a "slot number" during the initial software configuration
of the stack. Starting at the switch with the console connection, numbers are assigned in numerical
order following the physical path of the connected stacking cables. For example, if you follow the
cabling recommendations presented in
and configure the stack from the console on the switch at the top of the physical stack, the switches will
be assigned numbers 1 through 8 from the top down.
Each Summit switch has a seven-segment LED on its front panel, called the stack number indicator.
When a stack is operating, the indicator displays the slot number for the switch. (This LED does not
light on switches that are not operating in stacking mode.) A quick way to verify that the cable
connections match the software configuration is to check the stack number indicator on each switch. If
the slot numbers do not line up in the order you arranged the switches, this may indicate that the
stacking cable setup differs from what you intended when you configured the software. In this case,
reconnect the cables in the correct order and perform the software configuration again.
