Initial Configuration

2-6

will operate in Special Stacking Mode in which all backup units are disabled as

described below:

• The master unit starts normal operation mode in standalone mode.

• The master unit can see all units in the stack and maintain stack topology.

• None of the other units can function (all ports will be disabled).

• All user-initiated commands to configure the non-functioning units are dropped.

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 download 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 image”

and downloads the image to those backup units that are running a different image

version. For information on downloading firmware, see “Managing Firmware” 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 and use basic

utilities. To fully configure the switch parameters, you must access the CLI at the

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, perform these

steps:

1. To initiate your console connection, press <Enter>. The “User Access

Verification” procedure starts.

2. At the Username prompt, enter “admin.”

3. At the Password prompt, also enter “admin.” (The password characters are not

displayed on the console screen.)
