Connecting to the StackWise Plus Ports

Before you connect the StackWise Plus cables, review the “Planning and Creating a Switch Stack” 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 (Figure 2-11). Use a ratcheting torque screwdriver to tighten the retainer screws to 5 lbf-in. (80 ozf-in.).
