Configuring Switches in a Stack

3. The management election process uses the following precedence to assign a management
switch:
a. Previously assigned / elected management unit
b. Management assigned priority (values 1-15)
c. Hardware preference level
d. Highest MAC Address
Use the following recommended procedures when installing a new stackable system or adding a
new unit to an existing stack.
Installing a New Stackable System of Up to Eight Units
Use the following procedure for installing a new stack of up to eight units out of the box.
1. Before applying power, make sure all physical connections with the stack cables are the same
as described in the SecureStack A2 Installation Guide.
2. Once all of the stack cables have been connected, individually power on each unit from top to
bottom.
3. (Optional) If desired, change the management unit using the set switch movemanagement
command as described in Section 2.1.10.8.
4. Once the desired master unit has been selected, reset the system using the reset command as
described in Section 2.1.19.2.
5. After the stack has been configured, you can use the show switch unit command
(Section 2.1.10.2) to physically identify 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.
Important
The following procedures assume that all units have a clean configuration from manufacturing. When
adding a new unit to an already running stack, it is also assumed that the new unit is using the same
firmware image version as other units in the stack.
NOTES: Ensure that each switch is fully operational before applying power to the next switch.
Since unit IDs are assigned on a first-come, first-served basis, this will ensure that unit IDs are
ordered sequentially.
Once unit IDs are assigned, they are persistent and will be retained during a power cycle to any or
all of the units.
