Reference Guide

Begin with the first port on the management unit. Next, configure both ports on each subsequent
unit. Finally, return to the management unit and configure the last port. (refer to the following
example.)
The range is from 0 to 15.
6. Connect the units using stacking cables.
NOTE: The device does not require special stacking cables. The cables used to connect the
data ports are sufficient.
7. Reload the stack one unit at a time.
EXEC Privilege mode
show system brief
Start with the management unit, then the standby, then each of the members in order of their
assigned stack number (or the position in the stack you want each unit to take).
Allow each unit to completely boot, and verify that the stack manager detects the unit, then power
the next unit.
Example of a Syslog
In the following example, stack unit is the master management unit, stack unit 2is the standby unit. The
cables are connected to each unit.
Configure the stack groups on the units in the following order:
• Configure the first stack group on unit 1: stack-unit 1 stack-group 13
• Configure the stack groups on unit 2: stack-unit 2 stack-group 14 and stack-unit 2
stack-group 15
• Configure the stack groups on unit 3: stack-unit 3 stack-group 12 and stack-unit 3
stack-group 13
• Configure the stack groups on unit 4: stack-unit 4 stack-group 13 and stack-unit 4
stack-group 31
• Configure the final stack-group on unit 1 to complete the stack: stack-unit 1 stack-group 31
When the stack-group configuration is complete, the system prints a syslog for reload.

Reload each unit in the stack. After the reload is complete, the four units come up as a stack with unit 1 as
the management unit, unit 2 as the standby unit, and the remaining units as stack-members. All units in
the stack can be accessed from the management unit.
To view the stack unit information after the reload, use the show system brief command.
