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.

9 Configuring CMC to send alerts You can set alerts and actions for certain events that occur on the chassis. An event occurs when the status of a system component is greater than the pre-defined condition. If an event matches an event filter and you have configured this filter to generate an alert message (email alert or SNMP trap), then an alert is sent to one or more configured destinations such as email address, IP address, or an external server. To configure CMC to send alerts: 1. 2. 3. 4.
NOTE: For more information on configuring SNMP protocol and trap format, see the Dell Chassis Management Controller for PowerEdge FX2/FX2s RACADM Command Line Reference Guide. Configuring SNMP Trap Alert Destinations Using CMC Web Interface To configure IPv4 or IPv6 alert destination settings using CMC Web interface: 1. In the system tree, go to Chassis Overview, and then click Alerts > Trap Settings. The Chassis Event Alert Destinations page is displayed. 2.
NOTE: CMC uses a default SNMP community string as public. To ensure higher security, it is recommended to change the default community string and set a value which is not blank. You can configure up to four destinations to receive traps alerts. To add more destinations, repeat steps 2–5. NOTE: The commands in steps 2–5 overwrites any existing settings configured for the index specified (1–4). To determine whether an index has previously configured values, type: racadm getconfig -g cfgTraps -i .
where is a value between 1–4. CMC uses the index number to distinguish up to four configurable destination email addresses. 4. Specify a destination email address to receive the email alerts: racadm config -g cfgEmailAlert -o cfgEmailAlertAddress -i where is a valid email address, and is the index value you specified in step 4. 5.
10 Configuring user accounts and privileges You can setup user accounts with specific privileges (role-based authority) to manage your system with CMC and maintain system security. By default, CMC is configured with a default root account. As an administrator, you can set up user accounts to allow other users to access the CMC. You can set up a maximum of 16 local users, or use directory services such as Microsoft Active Directory or LDAP to setup additional user accounts.
Table 17. User Types (continued) Privilege Description NOTE: CMC users with the Chassis Configuration Administrator privilege can configure power settings. However, the Chassis Control Administrator privilege is required to perform chassis power operations, including power on, power off, and power cycle. User Configuration Administrator User can: • • • • Add a new user. Change the password of a user. Change the privileges of a user.
Table 17. User Types (continued) Privilege Description • • Graceful shutdown Server Reboot Test Alert User User can send test alert messages. Debug Command Administrator User can execute system diagnostic commands. Fabric A Administrator User can set and configure the Fabric A IOM. The CMC user groups provide a series of user groups that have pre-assigned user privileges.
Table 19.
If you are configuring a new CMC or if you have used the racadm racresetcfg command, the only current user account is default root account. The racresetcfg subcommand resets all configuration parameters to the default values. Any earlier changes are lost. NOTE: Users can be enabled and disabled over time, and disabling a user does not delete the user from the database.
Table 20.
Configuring generic LDAP users CMC provides a generic solution to support Lightweight Directory Access Protocol (LDAP)-based authentication. This feature does not require any schema extension on your directory services. A CMC administrator can now integrate the LDAP server user logins with CMC. This integration requires configuration on both LDAP server and CMC. On the LDAP server, a standard group object is used as a role group. A user who has CMC access becomes a member of the role group.
8. If you have selected Certificate Validation Enabled option, then in the Manage Certificates section, specify the CA certificate to validate the LDAP server certificate during SSL handshake and click Upload. The certificate is uploaded to CMC and the details are displayed. 9. Click Apply. The generic LDAP directory service is configured. Configuring generic LDAP directory service using RACADM To configure the LDAP directory service, use the objects in cfgLdap and cfgLdapRoleGroup RACADM groups.
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. 2. 3. 4. Start Internet Explorer. Click Tools > Internet Options > Connections. In the Local Area Network (LAN) settings section, click LAN Settings. 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.

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 supply and Redundancy policy changes in system event log Changes in the power supply state and power redundancy policy are recorded as events. Events related to the power supply that record entries in the system event log (SEL) are power supply insertion and removal, power supply input insertion and removal, and power supply output assertion and de-assertion. The following table lists the SEL entries that are related to power supply changes: Table 27.

AC Power Recovery If the AC power supply of a system is disrupted, the chassis is restored to the previous power state before the AC power loss. The restoration to the previous power state is the default behavior.
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.
NOTE: PCIe management is supported only for PowerEdge FX2s and not PowerEdge FX2. 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.
reassignment settings. When the compute sleds are powered on after the reassignment changes, the slots assigned to the compute sleds 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.
18 Troubleshooting and recovery This section explains how to perform tasks related to recovering and troubleshooting problems on the remote system using the CMC web interface. • • • • • • • • • • • • • Viewing chassis information. Viewing the event logs. Gathering configuration information, error status, and error logs. Using the diagnostic console. Managing power on a remote system.

Table 33. LED Color and Blinking Patterns (continued) Component Storage sled LED Color, Blinking Pattern Status Amber, blinking Fault Amber, blinking Fault Solid Blue No fault Troubleshooting Non-responsive CMC If you cannot log in to CMC using any of the interfaces (the web interface, Telnet, SSH, remote RACADM, or serial), you can verify the CMC functionality observing the LEDs on CMC. Observing LEDs to Isolate the Problem The CMC has an LED which changes color to indicate: Table 34.
• Problem: Storage Amber LED blinks. Resolution: Ensure that the storage module is inserted properly and check the chassis log for warning messages. This error can be cleared only if the underlying fault is addressed and the associated host is power cycled with the sled removed or through a sled virtual reseat. Problem: Storage module RAID firmware update is not effective.
NOTE: Electrostatic discharge (ESD) events can damage CMC. Under certain conditions, ESD may build up on your body or an object, and then discharge into your CMC. To prevent ESD damage, take precautions to discharge static electricity from your body while handling and accessing CMC outside the Chassis. 2. Remove the jumper plug from the password reset connector, and insert a 2-pin jumper to enable the default administrator account. To locate the password jumper on the CMC board, see the following figure.
