Enclosure Blowers
8–4 UltraSCSI RAID Enclosure
Error Condition Reporting
The EMU LEDs display both blower and overtemperature error conditions.
See Table 3–6 for the blower error conditions and the recommended
corrective action.
Replacing a Blower
When there is a malfunctioning blower the other blowers operating at high
speed increases air flow through the components enough to permit
continued operation without corrupting or losing data. However, DIGITAL
recommends that you replace a defective blower immediately. If you
remove a blower and do not replace it within 8 minutes, the EMU can
implement the standby power mode, thereby protecting the components.
Complete the procedures in Table 8–1 and Table 8–2 to replace a blower.
____________________ Caution ___________________
Operating an UltraSCSI enclosure with a blower removed
significantly changes the air flow pattern and reduces air flow
through the components, If you remove a blower and do not
replace it within 8 minutes, the EMU will automatically turn off
the dc power distribution.
