NOTE: When modifying CMC service port numbers for SSH, Telnet, HTTP, or HTTPS, avoid using commonly used ports
by OS services such as port 111. See Internet Assigned Numbers Authority (IANA) reserved ports at http://www.iana.org/
assignments/service-names-port-numbers/service-names-port-numbers.xhtml.
CMC includes a web server that is configured to use the industry-standard SSL security protocol to accept and transfer
encrypted data from and to clients over the Internet. The web server includes a Dell self-signed SSL Digital Certificate (Server
ID), and is responsible for accepting and responding to secure HTTP requests from clients. This service is required by the web
interface and remote RACADM CLI tool for communicating with CMC.
If the web server resets, wait at least one minute for the services to become available again. A web server reset usually happens
as a result of any of the following events:
● Network configuration or network security properties are changed through the CMC web user interface or RACADM.
● Web server port configuration is changed through the web user interface or RACADM.
● CMC is reset.
● A new SSL server certificate is uploaded.
NOTE: To modify service settings, you must have the Chassis Configuration Administrator privilege.
Remote syslog is an additional log target for CMC. After you configure the remote syslog, each new log entry generated by
CMC is forwarded to the respective destinations.
NOTE: Because the network transport for the forwarded log entries is UDP, there is no guaranteed delivery of log entries,
nor is there any feedback to CMC about whether the log entries were received successfully.
The reserved network ports for CMC and iDRAC communication are 21, 68, 69, 123, 161, 546, 801, 4003, 4096, 5985 to 5990,
6900, and 60106.
Configuring services using RACADM
To enable and configure the various services, use the following RACADM objects:
● cfgRacTuning
● cfgRacTuneRemoteRacadmEnable
For more information about these objects, see the Chassis Management Controller for PowerEdge FX2/FX2s RACADM
Command Line Reference Guide available at dell.com/support/manuals.
If the firmware on the server does not support a feature, configuring a property related to that feature displays an error. For
example, using RACADM to enable remote syslog on an unsupported iDRAC displays an error message.
Similarly, when displaying the iDRAC properties using the RACADM getconfig command, the property values are displayed as
N/A for an unsupported feature on the server.
For example:
$ racadm getconfig -g cfgSessionManagement -m server-1
# cfgSsnMgtWebServerMaxSessions=N/A
# cfgSsnMgtWebServerActiveSessions=N/A
# cfgSsnMgtWebServerTimeout=N/A
# cfgSsnMgtSSHMaxSessions=N/A
# cfgSsnMgtSSHActiveSessions=N/A
# cfgSsnMgtSSHTimeout=N/A
# cfgSsnMgtTelnetMaxSessions=N/A
# cfgSsnMgtTelnetActiveSessions=N/A
# cfgSsnMgtTelnetTimeout=N/A
Configuring CMC extended storage card
You can enable or repair the optional Removable Flash Media for use as an extended non-volatile storage. Some CMC features
depend on extended nonvolatile storage for their operation.
To enable or repair the Removable Flash Media using the CMC web interface:
1. In the left pane, go to Chassis Overview, and then click Chassis Controller > Flash Media.
2. On the Removable Flash Media page, from the drop-down menu, select one of the following as appropriate:
