Users Guide

CMC and iDRACs are now available on the network. You can access the CMC on the assigned IP address using the Web

interface or CLIs such as a serial console, Telnet, and SSH.

NOTE: After you have completed network setup through the LCD Configuration Wizard, the Wizard is no longer

available.

Interfaces and Protocols to Access CMC

After you have configured CMC network settings, you can remotely access CMC using various interfaces. The following table lists

the interfaces that you can use to remotely access CMC.

NOTE: Since telnet is not as secure as the other interfaces, it is disabled by default. Enable Telnet using Web, ssh, or

remote RACADM.

NOTE: Using more than one interface at the same time may generate unexpected results.

Table 8. CMC Interfaces

Interface Description

Web interface Provides remote access to CMC using a graphical user interface. The Web interface is built

into the CMC firmware and is accessed through the NIC interface from a supported Web

browser on the management station.

For a list of supported Web browsers, see the Supported Browsers section in the Chassis

Management Controller Version 5.0 Release Notes at dell.com/support/manuals.

Remote RACADM command line

interface

Use this command line utility to manage CMC and its components. You can use remote or

firmware RACADM:

• Remote RACADM is a client utility that runs on a management station. It uses the out-

of-band network interface to run RACADM commands on the managed system and

uses the HTTPs channel. The –r option runs the RACADM command over a network.

• Firmware RACADM is accessible by logging in to CMC using SSH or telnet. You can

run the firmware RACADM commands without specifying the CMC IP, user name, or

password. After you enter the RACADM prompt, you can directly run the commands

without the racadm prefix.

Chassis LCD Panel Use the LCD on the front panel to:

• View alerts, CMC IP or MAC address, user programmable strings.

• Set DHCP

• Configure CMC static IP settings.

• View CMC MAC address for the active CMC.

• View the CMC VLAN ID appended to the end of CMC IP, if the VLAN is already

configured.

Telnet Provides command line access to CMC through the network. The RACADM command line

interface and the connect command, which is used to connect to the serial console of a

server or IO module, are available from the CMC command line.

NOTE: Telnet is not a secure protocol and is disabled by default. Telnet transmits

all data, including passwords in plain text. When transmitting sensitive

information, use the SSH interface.

SSH Use SSH to run RACADM commands. It provides the same capabilities as the Telnet

console using an encrypted transport layer for higher security. The SSH service is enabled

by default on CMC and can be disabled.

WSMan The LC-Remote Services is based on the WS-Management protocol to do one-to-many

systems management tasks. You must use WSMan client such as WinRM client
