Concept Guide

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.
NOTE: Before executing show commands, you must wait for 10 to 15 seconds for the download-agent process to start.
To view the stack unit information after the reload, use the show system brief command.

The following example shows how to congure two new switches for stacking using 10G ports.
Dell-1(conf)#stack-unit 1 stack-group 0
Setting ports Te 1/1 Te 1/2 Te 1/3 Te 1/4 as stack group will make their interface configs
obsolete after
a reload.
[confirm yes/no]:yes
Dell-2(conf)#stack-unit 1 stack-group 0
Setting ports Te 1/1 Te 1/2 Te 1/3 as stack group will make their interface configs obsolete
after
a reload.
[confirm yes/no]:yes
