UltraSCSI RAID Enclosure 3–1
3
Environmental Monitoring Unit
(EMU)
The primary function of the EMU (Figure 3–1) is to monitor, process,
report, and display power distribution, temperature, blower, configuration,
SCSI addressing, I/O module, communications, and microcode status
information. The EMU and the array controller can exchange and process
some of this information.

___________________ Caution _____________________
Proper operation of an UltraSCSI subsystem requires an
operational EMU and PVA in each enclosure. You must also
establish communications links between the EMUs to ensure
proper subsystem operation and error reporting.
