Fan Properties
Use this window to view information about the enclosure’s fans.
The fans are a component of the enclosure’s cooling module. The following
table describes the fan properties.
Ty p e This property indicates whether the EMM is a SCSI SES
Module or a SCSI Terminator.
SCSI SES Module—A SCSI SES Module provides SES
and SAFTE reporting to the host server, control of all
system LED indicators, and monitoring of all
environmental elements, such as temperature sensors,
cooling modules, and power supplies.
SCSI Terminator—The SCSI Terminator card is only used
if the
220S or 221S enclosure is not configured with a
redundant SCSI SES Module type of EMM. In systems
equipped with two SCSI SES Modules, the SCSI
termination is done through the EMMs.
Firmware Version This property indicates the version of the firmware loaded
on the EMM. All EMM modules in the enclosure should
have the same level of firmware.
NOTE: For multiple backplanes, the firmware version
appears as upstream and downstream versions.
SCSI Rate This property displays the maximum SCSI speed that the
EMM in a SCSI enclosure supports.
