Building Stacks

Selecting Stacking Cables

Depending on the switch model and the number and type of stacking ports, the bidirectional stacking
link provides 40 Gbps, 80 Gbps, or 160 Gbps full-duplex bandwidth.
Stacking connections using the native stacking ports require stacking cables that are specific to the
type of stacking port. These cables are available from Extreme Networks in lengths from 0.5 meter to
100 meters.
Table 95 lists the cable types that have been verified by Extreme Networks for use as stack connection
hardware, along with the switches or modules with which each type is compatible.
Caution
Use of non-recommended cables or optics could cause stack instability.
Note
You can use certain other fiber cables and optical transceivers for stacking on X590, X690,
and X870 switches. Additional configuration is required. For details, see
Configuration for Optics on X590, X690, X695, and X870 Switches
