SWITCH REMOVED
FROM STACK
Removal of a stack unit results in one or more freed cables. In this example, there is a freed quad-
breakout cable (red) that was used to link the bottom unit to the one directly above it. The second
quad-breakout cable is then used to connect the top and bottom units to again complete the ring
topology.
Note: A QSFP+ quad-breakout cable is one that allows the user to connect one QSFP+ 40GE port
to four SFP+ 10GE ports.
Alternatively, once the unit is removed, the remaining quad-breakout cable could be replaced with a
QSFP+ cable to connect the top and bottom stack members. This would free up four SFP+ interfaces,
but requires the use of another QSFP+ interface. The interfaces used for stacking is based on the
user’s preference.
Validation
To validate the stack unit was removed and that the remaining stack members are still intact, go to
System > Stack Management > Stack Summary.
