6 Configuring CMC Chassis Management Controller enables you to configure properties, set up users, and alerts to perform remote management tasks. Before you begin configuring the CMC, you must first configure the CMC network settings to allow CMC to be managed remotely. This initial configuration assigns the TCP/IP networking parameters that enable access to the CMC. You can configure CMC using Web interface or Setting up Initial Access to CMC RACADM.
You can enable the DHCP to obtain an IP address from the DHCP server automatically. Enabling or disabling DHCP for DNS IP addresses By default, the CMC’s DHCP for DNS address feature is disabled. When enabled, this feature obtains the primary and secondary DNS server addresses from the DHCP server. While using this feature, you do not have to configure static DNS server IP addresses.
Viewing CMC network LAN settings using RACADM To view IPv4 settings, use the object cfgCurrentLanNetworking with the following subcommands: • • getniccfg getconfig To view IPv6 settings, use the cfgIpv6LanNetworking with the getconfig subcommand. To view IPv4 and IPv6 addressing information for the chassis, use the getsysinfo subcommand. For more information about the subcommands and objects, see the Chassis Management Controller for PowerEdge FX2/FX2s RACADM Command Line Reference Guide.
racadm config -g cfgIPv6LanNetworking -o cfgIPv6PrefixLength 64 racadm config -g cfgIPv6LanNetworking -o cfgIPv6Gateway Configuring IPv4 and IPv6 DNS settings • CMC Registration — To register the CMC on the DNS server, type: racadm config -g cfgLanNetworking -o cfgDNSRegisterRac 1 NOTE: Some DNS servers only register names of 31 characters or fewer. Make sure the designated name is within the DNS required limit.
The CMC cannot be cabled for Management Network Port redundancy prior to actually configuring it for this operation. The CMC must use the standard single network connection for deployment, after which the second redundant connection may be made. NOTE: When Management Port 2 is set for Redundant but is cabled for Stacking, the downstream CMCs (further from the TOR switch) will not have a network link.
• • • Kerberos NTP Client NFS NOTE: SNMP is not FIPS-compliant. In FIPS mode, all SNMP features except Message Digest algorithm version 5 (MD5) authentication work. Enabling FIPS Mode Using CMC Web Interface To enable FIPS: 1. In the left pane, click Chassis Overview. The Chassis Health page is displayed. 2. On the menu bar, click Network. The Network Configuration page is displayed. 3. Under the Federal Information Processing Standards (FIPS) section, from the FIPS Mode drop-down menu, select Enabled.

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.
• • • Quick launch links are available to open web pages for member chassis or servers. A server and Input/Output inventory is available for a group. A selectable option is available to synchronize a new member’s properties to the leader’s properties when the new member is added to the group. A chassis group may contain a maximum of 19 members. Also, a leader or member can only participate in one group. You cannot join a chassis, either as a leader or member, that is part of a group to another group.
Disbanding a Chassis Group To disband a chassis group from the lead chassis: 1. Log in with administrator privileges to the leader chassis. 2. Select the lead chassis in the left pane. 3. Click Setup > Group Administration. 4. In the Chassis Group page, under Role, select None, and then click Apply. The lead chassis then communicates to all the members that they have been removed from the group. The lead chassis can be assigned as a leader or member of a new group.
• Manual Propagation — Select this option for manual propagation of the chassis group leader properties with its members. The lead chassis property settings are propagated to group members only when a lead chassis administrator clicks Propagate. 5. In the Propagation Properties section, select the categories of lead configuration properties to be propagated to member chassis. Select only those setting categories that you want identically configured, across all members of the chassis group.
Chassis Configuration Profiles The Chassis Configuration Profiles feature enables you to configure the chassis with the chassis configuration profiles stored in the network share or local management station, and also restore configuration of the chassis.

To import the chassis configuration profiles from CIFS network share, type the following: racadm set –f clone.xml –t xml –l //xx.xx.xx.xx/PATH –u USERNAME –p PASSWORDCMC 2. To import the chassis configuration profiles from NFS network share, type the following: racadm set –f clone.xml –t xml –l xx.xx.xx.
When you query a specific CMC card using its group ID and object ID, RACADM creates the racadm.cfg configuration file from the retrieved information. By exporting the file to one or more CMCs, you can configure your controllers with identical properties in a minimal amount of time. NOTE: Some configuration files contain unique CMC information (such as the static IP address) that must be modified before you export the file to other CMCs. 1.
• All parameters are specified as "object=value" pairs with no white space between the object, =, or value. White spaces that are included after the value are ignored. A white space inside a value string remains unmodified. Any character to the right of the = (for example, a second =, a #, [, ], and so on) is taken as-is. These characters are valid modem chat script characters. [cfgLanNetworking] -{group name} cfgNicIpAddress=143.154.133.121 {object value} • The .cfg parser ignores an index object entry.
This file is updated as follows: # # Object Group "cfgLanNetworking" # [cfgLanNetworking] cfgNicIpAddress=10.35.9.143 # comment, the rest of this line is ignored cfgNicGateway=10.35.9.1 The command racadm config -f .cfg parses the file and identifies any errors by line number. A correct file updates the proper entries. Additionally, you can use the same getconfig command from the previous example to confirm the update.

11 Configuring CMC for Single Sign-On or Smart Card login This section provides information to configure CMC for Smart Card login and Single Sign-On (SSO) login for Active Directory users. SSO uses Kerberos as an authentication method allowing users, who have signed in as an automatic- or single sign-on to subsequent applications such as Exchange.
• For Single Sign-On or smart card login, the client system must be a part of the Active Directory domain and Kerberos Realm. CMC • • Each CMC must have an Active Directory account. CMC must be a part of the Active Directory domain and Kerberos Realm. Prerequisites for Single Sign-On or Smart Card login The pre-requisites to configure SSO or Smart Card logins are: • • • • • • Setup the Kerberos realm and Key Distribution Center (KDC) for Active Directory (ksetup).
Internet Explorer To edit the exception list in Internet Explorer: 1. Start Internet Explorer. 2. Click Tools > Internet Options > Connections. 3. In the Local Area Network (LAN) settings section, click LAN Settings. 4. In the Proxy server section, select the Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections) option, and then click Advanced. 5.
You can test the Active Directory using Kerberos authentication using the RACADM command: testfeature -f adkrb -u @ where is a valid Active Directory user account. A command success indicates that CMC is able to acquire Kerberos credentials and access the user's Active Directory account. If the command is not successful, resolve the error and run the command again.
12 Configuring CMC to use Command Line consoles This section provides information about the CMC command line console (or serial/Telnet/Secure Shell console) features, and explains how to set up the system so that you can perform systems management actions through the console. For information about using the RACADM commands in CMC through the command line console, see Chassis Management Controller for PowerEdge FX2/FX2s RACADM Command Line Reference Guide.
To fix this issue, download hotfix 824810 from support.microsoft.com. For more information, you can also see Microsoft Knowledge Base article 824810. Using SSH with CMC SSH is a command line session that includes the same capabilities as a Telnet session, but with session negotiation and encryption to improve security. CMC supports SSH version 2 with password authentication. SSH is enabled on the CMC by default. NOTE: CMC does not support SSH version 1.
NOTE: There is no GUI support for managing this feature, you can use only the RACADM. When adding new public keys, make sure that the existing keys are not already at the index, where the new key is added. CMC does not perform checks to ensure previous keys are deleted before a new one is added. As soon as a new key is added, it is automatically in effect as long as the SSH interface is enabled.
NOTE: The connect command provides the –b (binary) option. The –b option passes raw binary data, and cfgSerialConsoleQuitKey is not used. Additionally, when connecting to a server using the CMC serial console, transitions in the DTR signal (for example, if the serial cable is removed to connect a debugger) will not result in you exiting the application. NOTE: If the IOM does not support console redirection, the connect command displays an empty console.
5. Save the changes and exit. The managed system restarts. Configuring Windows for serial console redirection There is no configuration necessary for servers running the Microsoft Windows Server versions, starting with Windows Server 2003. Windows receives information from the BIOS, and enable the Special Administration Console (SAC) console one COM1. Configuring Linux for server serial console redirection during boot The following steps are specific to the Linux GRand Unified Bootloader (GRUB).
• • Disable GRUB's graphical interface and use the text-based interface. Else, the GRUB screen is not displayed in console redirection. To disable the graphical interface, comment out the line starting with splashimage. To start multiple GRUB options to start console sessions through the serial connection, add the following line to all options: console=ttyS1,57600 The example shows console=ttyS1,57600 added to only the first option.
1:2345:respawn:/sbin/mingetty 2:2345:respawn:/sbin/mingetty 3:2345:respawn:/sbin/mingetty 4:2345:respawn:/sbin/mingetty 5:2345:respawn:/sbin/mingetty 6:2345:respawn:/sbin/mingetty tty1 tty2 tty3 tty4 tty5 tty6 # Run xdm in runlevel 5 # xdm is now a separate service x:5:respawn:/etc/X11/prefdm -nodaemon Edit the /etc/securettyfile as follows: Add a new line, with the name of the serial tty for COM2: ttyS1 The following example shows a sample file with the new line.
13 Using FlexAddress and FlexAddress Plus cards This section provides information about FlexAddress and how to use FlexAddress Plus card to configure FlexAddress. NOTE: The FlexAddress feature is licensed. This feature license is included in the Enterprise License.
For example: (starting_mac)00:18:8B:FF:DC:FA + (mac_count)0xCF – 1 = (ending_mac)00:18:8B:FF:DD:C8 NOTE: Lock the SD card prior to inserting in the USB Memory Card Reader to prevent accidently modifying any of the contents. You must unlock the SD card before inserting into CMC.
Dell Feature Cards may contain more than one feature. Once any feature included on a Dell Feature Card has been activated on a chassis, any other features that may be included on that Dell Feature Card cannot be activated on a different chassis.
Configuring FlexAddress for chassis-level fabric and slots At the chassis level, you can enable or disable the FlexAddress feature for fabrics and slots. FlexAddress is enabled on a per-fabric–basis and then slots are selected for participation in the feature. Both fabrics and slots must be enabled to successfully configure FlexAddress.

16 Managing and monitoring power The PowerEdge FX2/FX2s chassis is the most power-efficient server enclosure. It is designed to include highly efficient power supplies and fans, has an optimized layout for the air to flow more easily through the system, and contains power-optimized components throughout the enclosure.
Grid Redundancy policy The Grid Redundancy policy is also knows as 1+1 policy, for one active and one spare PSU. The purpose of the Grid Redundancy policy is to enable an enclosure system to operate in a mode in which the enclosure can tolerate AC power failures. These failures may originate in the AC power grid, the cabling and delivery, or a Power Supply Unit (PSU) itself. When you configure a system for Grid Redundancy, connect PSUs 1 and 2 to separate power grids.
Viewing power consumption status CMC provides the actual input power consumption for the entire system. Viewing power consumption status using CMC web interface In the left pane, click Chassis Overview > Power > Power Monitoring. The Power Monitoring page displays the power health, system power status, real-time power statistics, and real-time energy statistics. For more information, see the Online Help. NOTE: You can also view the power redundancy status under Power Supplies.
Power management after PSU failure In the event of a PSU failure or removal, the power supplied to servers may be reduced. In extreme cases servers could be powered off in an attempt to sustain operation. Configuring and maintaining Grid Redundancy avoids any impact to servers for a single PSU failure. Power supply and Redundancy policy changes in system event log Changes in the power supply state and power redundancy policy are recorded as events.
Configuring power budget and Redundancy using CMC web interface NOTE: To perform power management actions, you must have the Chassis Configuration Administrator privilege. To configure power budget: 1. In the left pane, click Chassis Overview > Power > Configuration. 2. On the Budget/Redundancy Configuration page, select any or all of the following properties as appropriate. For information about the field descriptions, see the Online Help.

NOTE: This setting is applicable only to multi-node Sleds present in the chassis. Other Sleds are not affected.
17 Configuring PCIe slots The PowerEdge FX2/FX2s chassis optionally contain eight PCIe slots where each PCIe slot is assigned to a specific sled. By default, all PCIe slots are mapped. You can enable or disable the assignment of PCIe slots to the servers using the CMC web interface or RACADM commands. The following tables list the PCIe mapping for full-width, half-width, and quarter-width compute sleds. Table 29.
For more information about mapping PCIe slots, see the Dell PowerEdge FD332 Owner’s Manual. For more information about managing PCIe slots, see the CMC for Dell PowerEdge FX2/FX2s Online Help. NOTE: The Agent-free monitoring feature is not available for the PCIe PERC and Network cards in the Chassis PCIe slots. Agent-free monitoring is the systems management solution for Dell’s 12th generation of PowerEdge servers. It is out-of-band with no dependence on any operating system agents.
in the lower bay earlier, are mapped to corresponding compute sleds in the upper bay. Following are some examples for PCIe reassignment: • PCIe reassignment in full-width (FW) FC830: • • PCIe slots mapped to FW sled-3 (PCIe slots 1 through 4) are reassigned to sled–1. Sled-1 now maps to PCIe slots 1 though 8. PCIe reassignment in half-width (HW) FC630: • • PCIe slots mapped to HW sled-3 (PCIe slots 5 and 6) are reassigned to sled-1.
