Control and monitoring of the enclosure elements can be transferred from one EMM to another in the event of an EMM failure. A failover occurs whenever communication is lost between an EMM and its peer. In the event of a peer EMM failure, the surviving EMM activates the amber status LED of the failed EMM.
book.book Page 17 Monday, December 7, 2009 4:51 PM The alarm sounds every 10 seconds if: • One power supply has failed. • One cooling fan has failed. • One or more temperature sensors are in warning range. • One EMM has failed. NOTE: The alarm is disabled by default. To enable the alarm, you must change the default setting in Server Administrator. For more information, see the Server Administrator documentation at support.dell.com/manuals. Power Indicator Codes Figure 1-7.
