Stacking Cables - Extreme Networks Summit X150 Series Hardware Installation Manual

In a stack with multiple master-capable switches, it is possible for more than one switch to try become
the stack master if the stack is physically severed. Such a dual-master condition would cause confusion
and loss of connectivity in your network. To resolve a dual-master condition, you must be able to log in
to each severed stack segment, either over the management network (using the Ethernet management
port on a switch in the segment) or through a direct console port connection to each switch in the
segment.
Stack configuration, easy setup, and redundancy are fully described in the ExtremeXOS Concepts Guide.

Stacking Cables

Depending on the switch model and the number and type of stacking ports, the bidirectional stacking
link provides 40 Gbps, 80 Gbps, 128 Gbps, 160 Gbps, 256 Gbps, or 512 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 59 lists the cable types and compatible Summit switches or modules.
