X590 Stacking
X590 series switches can be stacked with other X590 switches, with X690 switches, X695 switches, and
with X870 switches. X590 series switches support native stacking using front-panel data ports 29 and
33.
Alternate stacking is not supported for X590 switches.
The stacking-support option is disabled by default for all X590 switches. For more information, see
Enabling and Disabling the Stacking-Support Option
on page 192.
summarizes stacking support for X590 switches.
Note
Only QSFP28 direct-attach passive copper cable, at lengths up to 5 meters, can be used in
X590 stacking ports.
