CPU to CPU packets are fine between 12 units.
NOTE
You should look for platform-level issues such as a bad cable or a wrong cable based on the errors
from the above debugging commands.

Use Cases

Adding a new unit to the stack
Adding a new unit to an already existing operational stack can be done in three ways.
• Secure setup
• Stack enable
• With reserved configuration
Assumptions
• This process assumes that a stack is already formed an operational.
• To add a new unit to the stack, the number of units in the stack should be less than 12.
Description
A new unit can be connected to one of the end units of the stack using t he stack ports. The following
section describes these processes.
Steps
Using secure setup method:
1. A new unit can be connected to one of the end units of the stack using stack ports.
2. If the unit is connected with set of re-timer ports 1/2/5 to 1/2/8, manually configure the default ports to
1/2/5 and 1/2/7.
3. Once link is up, enter 'stack secure setup 'on the active unit. The CLI display comes up with a 'new'
unit discovered and prompts the user to enter the number of units desired upstream/downstream
depending on where the new unit is connected.
4. The newly added unit receives a new ID which is next available ID, and resets itself. Upon boot up it
joins with newly assigned ID. Do 'write memory'.
Using manual configuration method:
1. A new unit can be connected to one of the end units using stack ports.
2. If the unit is connected with set of re-timer ports 1/2/5 to 1/2/8, manually configure the default ports to
1/2/5 and 1/2/7.
3. Configure stack-trunk if required.
4. When link come up, enter 'stack enable' on the new unit at configuration level.
5. The newly added unit receives a new ID, which is next available stack ID, and resets itself. Upon
boot up it joins with newly assigned ID. Do 'write memory'.
Using reserved configuration method:
1. Module configuration of the new unit should be configured on the active unit.
2. This new unit then can be connected to one of the end units using stack ports.
3. Active controller resets the new unit and upon boot up, the new unit is part of the stack. Do 'write
memory'.
