Installing a New Stackable System of Up to Eight Units
2-2 Configuring Switches in a Stack
• The console port on the manager switch remains active for out ‐ of ‐ band (local) switch
management, but the console port on each member switch is deactivated. This enables you to
set the IP address and system password using a single console port. Now each switch can be
configured locally using only the manager’s console port, or inband using a remote device
and the CLI set of commands described in this section.
Once a stack is created (more than one switch is interconnected), the following procedure occurs:
1. By default, unit IDs are arbitrarily assigned on a first ‐ come, first ‐ served basis.
2. Unit IDs are saved against each module. Then, every time a board is power ‐ cycled, it will
initialize with the same unit ID. This is important for port ‐ specific information (for example:
ge.4.12 is the 12th Gigabit Ethernet port on Unit # 4).
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 all physical connections with the stack cables as described in
the SecureStack C2 Installation Guides.
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 “ set switch movemanagement ” on page 2 ‐ 11.
4. Once the desired master unit has been selected, reset the system using the reset command as
described in “ reset ” on page 3 ‐ 47.
5. After the stack has been configured, you can use the show switch unit command (“ show
switch ” on page 2 ‐ 6) 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.
