To create a switch stack:

Step 1 Install the member switch modules if you have not already done so.

Step 2 Connect the StackWise Plus cables as described in the “Planning and Creating a Switch Stack

(Only the Cisco Catalyst Blade Switch 3120 for HP)” section on page 21.

Step 3 Configure the member switch modules through the master switch by using the CLI.

Stack Cabling Configurations

This example shows a single chassis with two switches that create one stack. The stack uses the 1-meter

StackWise Plus cable to make redundant connections between two 3120 switches. Other types of

configurations are possible provided that you stack no more than nine switches. For more stacking

configuration examples, see the hardware installation guide.

Connecting the StackWise Plus Cables

Follow these steps:

Step 1 Remove the dust covers from the StackWise Plus cables and store them for future use.

Step 2 Verify that cables are aligned as shown in Figure 11.

Step 3 Insert the cable into the StackWise Plus port on the front panel of the switch. Insert the other

end of the cable into the connector of the other switch.

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