A change to this setting on either SM module is automatically updated
on the other SM module.
Figure 167 shows the temperature and voltage thresholds for each
alarm and what to do to resolve the problem.

Alarm threshold What to do when the alarm sounds
EF2800 internal
temperature
• Warning: 0°C to 4°C and
66°C to 70°C
• Shutdown: <0°C and
>70°C
• Check the Disk Array Administrator software to
confirm what the alarm means. See section E.2
on
page 260.
• Check the ambient temperature and lower it, if
needed. Ambient temperature should be less
than 45°C.
•Check that the
EF2800 has good airflow
clearance. The EF2800 requires airflow
clearance on all sides, except the bottom and
top.
• Check that the internal fans are running. The fans
are in the Power Managers.
EF2800 CPU temperature
• Warning: 0°C to 4°C and
91°C to 100°C
• Shutdown: <0°C and
>100°C
• Same as above.
VCC voltage
• Warning: 5 V -10% to -8%
and +8% to +10%
• Shutdown: 5 V <-10% and
>+10%
• Check the Disk Array Administrator software to
confirm what the alarm means. See section
E.2
on page 260.
• If it is a warning alarm, let the
EF2800 continue
to operate.
• If it is a shutdown alarm, see which SM module is
showing the alarm. If only one SM module shows
the alarm, replace that SM module. If it is both,
you must troubleshoot the Power
Supply/Cooling modules.
