card contains an XML tag mac_start that is the first starting hex MAC address that is used for this unique MAC address range. The mac_count tag is the total number of MAC addresses that the SD card allocates.
Table 26. Status Messages Returned by the featurecard -s Command Status Message Actions No feature card inserted. Check CMC to verify that the SD card was properly inserted. In a redundant CMC configuration, ensure that the CMC with the SD feature card installed is the active CMC and not the standby CMC.
Deactivating FlexAddress The FlexAddress feature can be deactivated and the SD card returned to a preinstallation state by using a RACADM command. There is no deactivation function within the Web interface. Deactivation returns the SD card to its original state where it can be installed and activated in another chassis.
NOTE: FlexAddress does not take effect on a server module until the next reboot. When the FlexAddress feature is deployed for the first time on a given server module, it requires a power- down and power-up sequence for FlexAddress to take effect. FlexAddress on Ethernet devices is programmed by the server module BIOS.
For more information about the setflexaddr command, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide . NOTE: If you purchase the FlexAddress or FlexAddressPlus feature with your Dell PowerEdge VRTX, it is preinstalled and enabled for all slots and fabrics.

13 Managing Fabrics The chassis supports a fabric type, which is Fabric A. Fabric A is used by the single I/O Module, and is always connected to the on-board Ethernet adapters of the servers. The chassis has only one I/O module (IOM), where the IOM is a pass-through or switch module.
NOTE: For Ethernet switches, the in-band (VLAN1) and out-of-band management IP addresses cannot be the same, or cannot be on the same network. This results in the out-of-band IP address in being not set. See the IOM documentation for the default in-band management IP address.
14 Managing and Monitoring Power The PowerEdge VRTX chassis is the most power-efficient modular 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.
Redundancy Policies Redundancy policy is a configurable set of properties that determine how CMC manages power to the chassis. The following redundancy policies are configurable with or without dynami.
PSUs beyond those required for power and redundancy are still available and is added to the pool in the event of a failure. Unlike Grid redundancy, when power supply redundancy is selected, CMC does not require the PSU units to be present in any specific PSU slot positions.
An increase in power demand in the Grid Redundancy configuration cause the engagement of PSUs from the Standby state. This maintains the mirrored configuration needed for dual-grid redundancy.
CMC allocates power to the CMC infrastructure and the servers in the chassis. CMC infrastructure consists of components in the chassis, such as fans, I/O module, and storage adapters, PCIe cards, physical disk, main board. The chassis may have up to four servers that communicate to the chassis through an iDRAC.
Additional servers can be powered up in the modular enclosure only if sufficient power is available. The System Input Power Cap can be increased any time up to a maximum value of 5000 Watt to allow the power up of additional servers.
Assigning Priority Levels To Servers Using CMC Web Interface To assign priority levels: 1. In the left pane, click Server Overview → Power → Priority .
Viewing Power Budget Status Using RACADM Open a serial/Telnet/SSH text console to CMC, log in, and type: racadm getpbinfo For more information about getpbinfo , including output details, see the getpbinfo command section in the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide .
the chassis that is below what would be required for full power allocation to the servers, or if insufficient power is available in case higher power requirements by all servers in the chassis. If enough power cannot be freed by reducing the allocated power of the low-priority servers, the new server is not allowed to turn on.
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 entr.
Power Conservation and Power Budget CMC conserves power when the user-configured maximum power limit is reached. When the demand for power exceeds the user configured System Input Power Cap, CMC reduces power to servers in reverse-priority order to free power for higher priority servers and other modules in the chassis.
those power supplies connected to the other voltage level are turned off and indicated as not functioning. Remote Logging Power consumption can be reported to a remote syslog server.

16 Managing PCIe Slots By default, all slots are unmapped. You can do the following: • View the status of all PCIe Slots in the chassis. • Assign or remove an assigned PCIe slot from the servers. Consider the following before assigning a PCIe slot to a server: • An empty PCIe slot cannot be assigned to a server that is turned on.
• Without a license, the maximum number of PCIe slots that maybe mapped to a half-height server is two. If a full-height server is installed you can map two PCIe slots to the upper server slot and two to the lower (extended) server slot, for a total of four PCIe slots per full-height server .
All these processes require few seconds to complete which causes a delay in initialization of the PCIe cards. The PCIe Ride-through feature in CMC VRTX reduces this process cycle time. The PCIe Ride- through feature enables the following: • The Server nodes are turned on quickly, thus turning on the PCIe cards quickly.
4. Click Apply . Configuring PCIe Ride-through Properties Status Using RACADM You can configure the PCIe power ride-through properties, by running the following commands: • To disable the Ride-throu.

19 Frequently Asked Questions This section lists the frequently asked questions about the following: • RACADM • Managing and Recovering a Remote System • Active Directory • FlexAddress and Fle.
Managing and Recovering a Remote System Why are the remote RACADM and Web-based services unavailable after a property change? It may take a minute for the remote RACADM services and the web interface to become available after the CMC Web server resets.
When accessing the CMC Web interface, a security warning stating that the host name of the SSL certificate does not match the host name of CMC is displayed. CMC includes a default CMC server certificate to ensure network security for the web interface and remote RACADM features.
Are there any restrictions on Domain Controller SSL configuration? Yes. All SSL certificates for Active Directory servers in the forest must be signed by the same root certificate authority-signed certificate, because CMC only allows upload of one trusted certificate authority-signed SSL certificate.
If the chassis service tag is reprogrammed, what happens if there is a feature card bound to that chassis? • If the original feature card is present in the active CMC on that or any other chassis, the Web interface displays the following error message: This feature card was activated with a different chassis.
What happens to FlexAddress if I need to reset my chassis configuration using the RACADM command, racresetcfg? The FlexAddress feature will still be activated and ready to use. All fabrics and slots are selected as default. NOTE: It is highly recommended that you turn off your chassis before running the RACADM command racresetcfg.
