Summit Family Switches Hardware Installation Guide
159
Summit X650 series switches:
●
Summit X650 series switches must always have an installed VIM1 module.
●
If a VIM1-SummitStack or VIM1-SummitStack256 module is installed, ports 23 and 24 on the switch
front panel can be configured as alternate stacking ports.
●
If a VIM1-10G8X module is installed, ports 31 and 32 on the VIM1-10G8X module can be configured
as alternate stacking ports.
Summit X670 series switches:
Only alternate stacking ports are supported on the Summit X670-48x switch. When ports 47 and 48
are used as alternate stacking ports, ports 45 and 46 are not available to use as data ports.
Connecting the Switches to Form the Stack Ring
After you have installed the individual Summit switches (see
Chapter 6
), connect the switches together
using the stacking cables. The examples in this section show cable connections and the recommended
order for connecting ports to facilitate the easy setup configuration.
In general, it is best to connect Stack Port 2 on one switch to Stack Port 1 on the switch with the next
higher slot number. Although you can connect the switches in any order, connecting them as shown in
these examples will produce better predictability and easier software configuration. It is essential to
create an unbroken data path through all the switches in the stack.
NOTE
The connection recommendations in this section do not apply to Summit X650 series switches with
installed VIM1-SummitStack512 modules. For information about connecting the ports on the VIM1-SummitStack512
modules, see
“Using the VIM1-SummitStack512 Module” on page 168
.
For instructions to connect specific types of stacking cables, see
“Connecting Stacking Cables” on
page 171
.
Using SummitStack Ports and 40G Stacking Cables
SummitStack ports are integrated into the back panel of the Summit X250e, X450, X450a, and X450e
series switches. In addition, the X460, X480, and X650 series switches accommodate VIMs or stacking
modules that provide SummitStack ports.
The examples in this section show physical stacking arrangements that include all switches in a single
rack, switches in two adjacent racks, and switches at the tops of several racks in a row.
