Connecting FlexStack-Extended modules (Optional)
Procedure
Step 1 Remove the dust covers from the FlexStack cables, and store them for future use.
Step 2 Insert one end of the FlexStack cable into the stack port of the first switch. Insert the other end of the cable
into the stack port on the other switch. Make sure that you insert the cables in completely until you feel them
snap into place.
Note
Step 3 Replace the dust covers when you remove the FlexStack cables from the connectors.
Caution
Connecting FlexStack-Extended modules (Optional)
Always use a Cisco-approved FlexStack cable to connect the switches.
This is only supported on the stack-capable switches.

Removing and installing the FlexStack cable can shorten its useful life. Do not remove and insert
the cable more often than is absolutely necessary.
