Stack Cabling Managing OmniSwitch 6850 Series Stacks
page 4-18 OmniSwitch 6850 Series Hardware Users Guide April 2010
The figure below shows how the redundant connection between the top and bottom switches in the stack
ensures that data will continue to flow throughout the stack, even in the event of a connection failure at
one of the stacking cables.
Stacking Cable Redundancy: Recovery Following a Stacking Link Failure
Data enters slot 1 via a 10/100/1000 Ethernet port. The
data is passed to slot 2 over the stacking cable connection,
then exits slot 2 via one of its 10/100/1000 Ethernet.

The stacking connection between slots 1 and 2 goes
down unexpectedly. Data can no longer travel directly
between slot 1 and 2.
However, because there is a redundant connection (the
cable between slot 1 and slot 4), data is immediately
passed to slot 4, then quickly traverses slot 3 and exits
slot 2 to its destination.
