The stack takes about 10 seconds to reset. While the stack is resetting, 
you cannot communicate with it.
Initializing All the
Units in the Stack
You can initialize all the Switch units in the stack using the 
initialize
 
command on the System menu.
To initialize the units:
1
At the top-level menu, enter:
system initialize
The following prompt is displayed:
Initializes the system to factory defaults and causes a 
reset.
Do you wish to continue (yes,no) [no]:
2
Enter 
y
 if you wish to proceed, or 
n
 if you want to stop the initialization.
What Happens During an Initialization?
Initializing the Switch units in the stack returns them to their default 
(factory) settings. The only information that does not return to its default 
setting is the IP and SLIP information, which is retained to ensure that you 
can continue managing the stack. You may want to initialize the stack if it 
has previously been used in a different part of your network, and its 
settings are incorrect for the new environment.
CAUTION: 
Use great care when initializing the stack — it removes all 
configuration information, including password and security information.
CAUTION: 
When initializing the stack, network loops may occur if you 
have set up port trunks, resilient links, VLANs, or the Spanning Tree 
Protocol. Before initializing the stack, ensure you have disconnected the 
cabling for all standby or duplicate links.
The stack takes about 10 seconds to initialize. While the stack is 
initializing, you cannot communicate with it.
