Using remote access software from a management station

You can access CMC from a management station using various remote access software. Here is a list of remote access softwares by Dell which is available from your Operating System.

Table 1. CMC InterfacesThe following table contains descriptions of the CMC interfaces.
Interface/Protocol	Description
Serial	CMC supports a serial text console that can be launched using any terminal emulation software. Following are couple of examples of terminal emulation software that can be used to connect to CMC. Linux Minicom Hilgraeve’s HyperTerminal for Windows Connect one end of the serial null modem cable (present at both ends) to the serial connector on the back of the chassis. Connect the other end of the cable to management station serial port. For more information on connecting cables, refer to the back panel of the chassis in Chassis Overview section. Configure your terminal emulation software with the following parameters: Baud rate: 115200 Port: COM1 Data: 8 bit Parity: None Stop: 1 bit Hardware flow control: Yes Software flow control: No
Remote RACADM CLI	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, it requires CMC IP, username and password. To use remote RACADM from your management station, install remote RACADM using the Dell Systems Management Tools and Documentation DVD that is available with your system. For more information on Remote RACADM
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 Dell System Software Support Matrix at dell.com/support/manuals.
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.
SNMP	Simple Network Management Protocol (SNMP) is a set of protocol definitions for managing devices on the networks. The CMC provides access to SNMP, which allows you to use SNMP tools to query the CMC for Systems Management information. The CMC MIB file can be downloaded from the CMC Web interface, go to Chassis Overview > Network > Services > SNMP. See the Dell OpenManage SNMP Reference Guide for more information about the CMC MIB. The following example show how the net-snmp snmpget command can be used to get the chassis service tag from the CMC. snmpget -v 1 -c <CMC community name> <CMC IP address>.1.3.6.1.4.1.674.10892.2.1.1.6.0
WSMan	The WSMan Services is based on the Web Services for Management (WSMan) protocol to perform one-to-many systems management tasks. You can use WSMan client such as WinRM client (Windows) or the OpenWSMan client (Linux) to use the LC-Remote Services functionality. You can also use Power Shell and Python script the WSMan interface. WSMan is a Simple Object Access Protocol (SOAP)–based protocol used for systems management. CMC uses WS–Management to convey Distributed Management Task Force (DMTF) Common Information Model (CIM)–based management information. The CIM information defines the semantics and information types that can be modified in a managed system. The CMC WSMan implementation uses SSL on port 443 for transport security, and supports basic authentication. The data available through WS-Management is provided by CMC instrumentation interface mapped to the DMTF profiles and extension profiles. NOTE The SSL port used for transport security is the same as the CMC HTTPS port.
