Users Guide

This feature card was activated with a different chassis. It must be removed
before accessing the FlexAddress feature.
Current Chassis Service Tag = XXXXXXXX
Feature Card Chassis Service Tag = YYYYYYYY
The original feature card is no longer eligible for deactivation on that or any other chassis, unless Dell
Service re-programs the original chassis service tag back into a chassis, and CMC that has the original
feature card is made active on that chassis.
• The FlexAddress feature remains active on the originally bound chassis. The binding of that chassis
feature is updated to reflect the new service tag.
Is an error message displayed if two feature cards are installed in the redundant CMC system?
No, there is no error message displayed. The feature card in the active CMC is active and installed in the
chassis. The second card is ignored by CMC.
Does the SD card have a write protection lock on it?
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 firmware prior to 1.10?
• The FlexAddress feature and configuration 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 firmware 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 firmware upgrade was completed), and reconfiguring the feature.
What happens if a CMC unit is replaced with one that has firmware 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 firmware prior to 1.10, the
following procedure must be used to ensure the current FlexAddress feature and configuration is NOT
removed:
• Ensure the active CMC firmware is always version 1.10 or later.
