will operate in Special Stacking Mode in which all backup units are disabled as
described below:
• The master unit starts normal operation mo de in sta ndalone mode.
• The master unit can see all units in the stack and maintain s tack topol ogy.
• None of the other units can function (all ports will be disabled).
• All user-initiated commands to co nfigur e the non-f unctio ning units are dro pped.
The master unit, however, will be able to communicate the following information to
the non-functioning units:
- Image downloads
- Stack topology information
- System configuration information already stored on the master.
In Special Stacking mode, the master unit displays warning messages whenever you
log into the system through the CLI that inform you that an image downloa d is
required.
You can use the CLI, web or SNMP to download the runtime image from a TFTP
server to the master unit. The master unit stores the image as its “Next boot imag e”
and downloads the image to those backup units that are running a different image
version. For information on downloading firmware, see “Managing Fi rmwar e” on
page 4-21 or “File Management Commands” on page 23-10.
Basic Configuration

Console Connection

The CLI program provides two different command levels — normal access level
(Normal Exec) and privileged access level (Privileged Exec). The commands
available at the Normal Exec level are a limited subset of those available at the
Privileged Exec level and allow you to only display information a nd use ba sic
utilities. To fully configure the switch parameters, you must access the CLI at t he
Privileged Exec level.
Note:
You can only access the console interface through the Master unit in the stack.
Access to both CLI levels are controlled by user names and passwords. The switch
has a default user name and password for each level. To log into the CLI at the
Privileged Exec level using the default user name and password, perfor m these
