The availability of the DDM real-time information and the warning and alarm status is based on the transceiver. The transceiver may or may not indicate that DDM is supported. Although some Nokia SFPs support DDM, Nokia SFPs support DDM releases later than Release 2.0. Contact a Nokia technical support representative for more information about DDM support for specific 7210 SAS releases. Non-DDM and DDM-supported SFPs are distinguished by a specific value in their EEPROM.
Although DDM data may be available for SFPs that do not indicate DDM support in their EEPROM, Nokia has not validated or verified the accuracy of this information.
DDM information can be displayed for non-Nokia transceivers, but Nokia is not responsible for the formatting, accuracy, and other informational details.
