Establishing a Connection

Using the Chassis Management Module

Factory-Default vs. CMM-Assigned IP Addresses

CN4093 Application Guide for N/OS 8.4
The factory default settings permit initial switch administration through the
built‐in serial port, as well as default IP addresses on VLAN 1 and the out‐of‐band
management port.
To facilitate switch access, the in‐band and out‐of‐band management interfaces are
configured with factory default IP addresses, as follows:
VLAN 1/Interface 1: 192.168.49.50/24

 Out‐of‐band Management Port 1: 192.168.50.50/24
Remote access using the network requires the accessing terminal to have a valid,
routable connection to the switch interface. The client IP address may be
configured manually, or an IPv4 address can be provided automatically through
the switch using a service such as DHCP or BOOTP relay (see "BOOTP/DHCP
Client IP Address Services" on page
IPv6 stateless address configuration.
Note: Throughout this manual, IP address is used in places where either an IPv4 or
IPv6 address is allowed. IPv4 addresses are entered in dotted‐decimal notation (for
example, 10.10.10.1), while IPv6 addresses are entered in hexadecimal notation (for
example, 2001:db8:85a3::8a2e:370:7334). In places where only one type of address is
allowed, IPv4 address or IPv6 address is specified.
The CN4093 is an integral subsystem within the overall Lenovo Flex System. The
Flex System chassis includes a chassis management module (CMM) as the central
element for overall chassis management and control.
The CN4093 uses port 43 (MGT1) to communicate with the chassis management
module(s). Even when the CN4093 is in a factory default configuration, you can
use the 1Gb Ethernet port on each CMM to configure and manage the CN4093.
For more information about using the chassis management module, see the Lenovo
Flex System Fabric CN4093 10 Gb Converged Scalable Switch Installation Guide.
Each CN4093 must be assigned its own Internet Protocol version 4 (IPv4) address,
which is used for communication with an SNMP network manager or other
transmission control protocol/Internet Protocol (TCP/IP) applications (for example,
BOOTP or TFTP). The factory‐default IPv4 address is 10.90.90.x, where x is based
on the number of the bay into which the CN4093 is installed. For additional
information, see the Installation Guide. The chassis management module assigns an
IPv4 address of 192.168.70.1xx, where xx is also based on the number of the bay
into which each CN4093 is installed, as shown in the following table:
