Configuring Switches in a Stack
SecureStack A2 Configuration Guide 2-21
Installing a Previously-Configured System of Up to Eight Units
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 Section 2.1.10.2 to display stacking information.
4. Clear any switches which are listed as “unassigned” using the clear switch member command
as described in Section 2.1.10.10.
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:
• Renumber the stack using the set switch renumber command as described in
Section 2.1.10.6, then
• 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
(Section 2.1.10.2) 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 configuration, 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).
