Adding a Unit to the Stack
The recommended procedure to add a unit to a stack is as follows:
1
Place the powered-off unit in its physical place in the stack, and insert the
stacking link in the unit (but do not connect it to the rest of the stack).
2
Power up the unit, and set the correct Unit ID, as described below.
3
Reboot the unit and connect it to the rest of the stack through the stack
link.
Assigning Unit IDs
Each unit in the stack has a unique ID that defines the unit’s position and
function in the stack, as shown in Figure 5-2.
The unit that is assigned Unit ID 1 is the Master unit, by default. The unit
that is assigned Unit ID 2 is the Master Backup unit.
When you power-up the stack, each unit is assigned a unique Unit ID. This is
displayed on the front panel of the unit, as shown in Figure 5-2.
The Unit ID of each unit can be either automatically assigned or manually
assigned, as described in step 1 to step 4 below.
To assign IDs to the units in the stack, do the following for each unit in the
stack:
1
Connect the unit to the terminal.
