Connecting to the StackWise Plus Ports

Before you connect the StackWise Plus cables, review the

section on page 2-13

. Always use a Cisco-approved StackWise Plus cable to connect the switches.

Follow these steps to connect the StackWise Plus cable to the StackWise Plus ports:

Step 1

Remove the dust covers from the StackWise Plus cables and StackWise Plus ports, and store them for
future use.

Step 2

Use the window in the StackWise Plus cable to align the connector correctly. Insert the cable into the
StackWise Plus port on the front of the switch module (

). Use a ratcheting torque screwdriver

to tighten the retainer screws to 5 lbf-in. (80 ozf-in.).
