Installing Previously-Configured Systems in a Stack

Installing Previously-Configured Systems in a Stack

If member units in a stack have been previous members of a different stack, you may need to configure the renumbering of the stack as follows:

1.Stack the units in the method desired, and connect the stack cables.

2.Power up only the unit you wish to be manager.

3.Once the management unit is powered up, log into the CLI, and use the show switch command as described in “show switch” on page 2‐6 to display stacking information.

4.Clear any switches which are listed as “unassigned” using the clear switch member command as described in “clear switch member” on page 2‐12.

5.Power up the member of the stack you wish to become unit 2. Once the second unit is fully powered, the COM session of the CLI will state that a new CPU was added.

6.Use the show switch command to redisplay stacking information.

a.If the new member displays as unit 2, you can proceed to repeat this step with the next unit.

b.If the new member displays a different unit number, you must:

(1)Renumber the stack using the set switch renumber command as described in “set switch” on page 2‐9, then

(2)Clear the original unit number using the clear switch member command.

7.Repeat Step 6 until all members have been renumbered in the order you desire.

8.After the stack has been reconfigured, you can use the show switch unit command (“show switch” on page 2‐6) to physically confirm the identity of each unit. When you enter the command with a unit number, the MGR LED of the specified switch will blink for 10 seconds. The normal state of this LED is off for member units and steady green for the manager unit.

Adding a New Unit to an Existing Stack

Use the following procedure for installing a new unit to an existing stack configuration. This procedure assumes that the new unit being added has a clean configuration from manufacturing and is running the same firmware image version as other units in the stack.

1.Ensure that power is off on the new unit being installed.

2.Use one of the following methods to complete stack cable connections:

–If the running stack uses a daisy chain topology, make the stack cable connections from the bottom of the stack to the new unit (that is, STACK DOWN port from the bottom unit of the running stack to the STACK UP port on the new unit).

–If the running stack uses a ring stack topology, break the ring and make the stack cable connections to the new unit to close the ring.

3.Apply power to the new unit.

Creating a Virtual Switch Configuration

You can create a configuration for a SecureStack C3 switch before adding the actual physical device to a stack. This preconfiguration feature includes configuring protocols on the ports of the “virtual switch.”
