What Happens During an Initialization?
Initializing the Switch units in the stack returns them to their default
(factory) settings. You may want to do this if the stack has previously
been used in a different part of your network, and its settings are
incorrect for the new environment.
ATTENTION: Use great care when initializing the stack — it removes all
configuration information, including security, resilient links and
passwords. However, IP and SLIP information is retained to ensure that
you can continue managing the stack.
ATTENTION: When initializing the stack, note that network loops occur
if you have set up resilient links. Before initializing the stack, ensure you
have disconnected the cabling for all standby links.
The stack takes about 10 seconds to initialise. While the stack is
initializing, the command line interface cannot communicate with the
stack.
Upgrading the
Management
Software of the
Stack
You can upgrade the management software of the Switch units in the
stack using the
softwareUpgrade
command on the System menu.
To upgrade the management software:
1 Copy the software upgrade file into an appropriate directory on a TFTP
server. For information on using a TFTP Server, see the documentation
that accompanies it.
2 From the Top-level menu, enter:
system softwareUpgrade
The following prompt is displayed:
TFTP Server Address [0.0.0.0]:
3 Enter the IP address of the TFTP server that holds the software upgrade
file. The file must be stored somewhere that is accessible to the TFTP
load request. Contact your system administrator if you are unsure
where to place the image file.
The following prompt is displayed:
File name [nwsxx_yy.bin]:
