CN4093 Application Guide for N/OS 8.4
The switch software provides a variety of user‐interfaces for administration. These
interfaces vary in character and in the methods used to access them: some are
text‐based, and some are graphical; some are available by default, and some
require configuration; some can be accessed by local connection to the switch, and
others are accessed remotely using various client applications. For example,
administration can be performed using any of the following:
 The Flex System chassis management module tools for general chassis
management
 A built‐in, text‐based command‐line interface and menu system for access via
serial‐port connection or an optional Telnet or SSH session
 The built‐in Browser‐Based Interface (BBI) available using a standard
web‐browser
 SNMP support for access through network management software such as IBM
Director.
The specific interface chosen for an administrative session depends on user
preferences, as well as the switch configuration and the available client tools.
In all cases, administration requires that the switch hardware is properly installed
and turned on. (see the Lenovo Flex System Fabric CN4093 10 Gb Converged Scalable
Switch Installation Guide).
The CN4093 10 Gb Converged Scalable Switch is an integral subsystem within the
overall Lenovo Flex System. The Flex System chassis also includes a chassis
management module (CMM) as the central element for overall chassis
management and control. Using the tools available through the CMM, the
administrator can configure many of the CN4093 features and can also access other
CN4093 administration interfaces.

The Industry Standard Command Line Interface (ISCLI) provides a simple, direct
method for switch administration. Using a basic terminal, you can issue
commands that allow you to view detailed information and statistics about the
switch, and to perform any necessary configuration and switch software
maintenance.
You can establish a connection to the CLI in any of the following ways:
 Serial connection via the serial port on the CN4093 (this option is always avail‐
able)
 Telnet connection over the network
 SSH connection over the network
When you first access the switch, you must enter the default username and
password: USERID; PASSW0RD (with a zero). You are required to change the
password after first login.
