Yes it does. Before installing the SD card into the CMC module, verify the write protection latch is in the unlock position. The
FlexAddress feature cannot be activated if the SD card is write protected. In this situation, the $racadm feature -s command returns
this message:
No features active on the chassis. ERROR: read only file system
What happens if there is no SD card in the active CMC module?
The $racadm featurecard -s command returns this message:
No feature card inserted.
What happens to FlexAddress feature if the server BIOS is updated from version 1.xx to version 2.xx?
The server module needs to be powered down before it can be used with FlexAddress. After the server BIOS update is complete,
the server module does not get chassis-assigned addresses until the server has been power cycled.
What happens if a chassis with a single CMC is downgraded with rmware prior to 1.10?
• The FlexAddress feature and conguration is removed from the chassis.
• The feature card used to activate the feature on this chassis is unchanged, and remains bound to the chassis. When this
chassis’s CMC rmware is subsequently upgraded to 1.10 or later, the FlexAddress feature is reactivated by reinserting the original
feature card (if necessary), resetting CMC (if feature card was inserted after rmware upgrade was completed), and
reconguring the feature.
What happens if a CMC unit is replaced with one that has rmware prior to 1.10 in a chassis with redundant CMCs?
In a chassis with redundant CMCs, if a CMC unit is replaced with one that has rmware prior to 1.10, the following procedure must
be used to ensure the current FlexAddress feature and conguration is NOT removed:
• Ensure the active CMC rmware is always version 1.10 or later.
• Remove the standby CMC and insert the new CMC in its place.
• From the Active CMC, upgrade the standby CMC rmware to 1.10 or later.
NOTE: If the standby CMC rmware is not updated to 1.10 or later and a failover occurs, the FlexAddress feature is not
congured. The feature must be reactivated and recongured again.
How can a SD card be recovered if the SD card was not in the chassis when the deactivation command was executed on the
FlexAddress?
The issue is that the SD card cannot be used to install FlexAddress on another chassis if it was not in CMC when the FlexAddress
was deactivated. To recover use of the card, insert the card back into a CMC in the chassis that it is bound to, reinstall FlexAddress,
and then deactivate FlexAddress, again.
The SD card is properly installed and all the rmware or software updates are installed. The FlexAddress is active, but the
server deployment screen does not display the options to deploy it? What is wrong?
This is a browser caching issue. Shut down the browser and relaunch.
What happens to FlexAddress if I need to reset my chassis conguration 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 o the chassis before issuing the RACADM command racresetcfg.
After disabling only the FlexAddressPlus feature (leaving FlexAddress still activated), why does the racadm setexaddr
command on the (stillactive) CMC fail?
If the CMC subsequently becomes active with the FlexAddressPlus feature card still in the card slot, the FlexAddressPlus feature
gets re-activated, and the slot or fabric exaddress conguration changes can resume.

The message "User has been disabled by CMC control" appears on the monitor connected to the front panel. Why?
The front panel connection has been disabled by CMC. Enable the front panel using either the CMC Web interface or RACADM.
To enable the front panel using the CMC Web interface, go toiKVM → Setup tab, select the Front Panel USB/Video Enabled
option, and click Apply to save the setting.
To enable the front panel using RACADM, open a serial/Telnet/SSH text console to CMC, log in, and type:
